TL;DR
A Delaware storefront window route needs a state business license from the Division of Revenue. There is no statewide washer board. An LLC costs $90 to file and $300 a year if you want the entity. Cities may add a local license. Confirm every fee with the board that bills it. Most first-year money goes to gear, a car, and liability insurance, not a thick permit stack.
How much does storefront windows cost in Delaware?
Starting a storefront window cleaning route in Delaware costs a few hundred dollars of state paper if you form an LLC, a city license if you work inside city limits, insurance that dwarfs those filings, and gear you can keep under a couple thousand dollars if you stay on the sidewalk. If you mean paying a washer for one shopfront, there is no public Delaware price index. Operators set that block by block.
The paper you can actually look up is small. The Division of Corporations publishes a $90 fee to file a Certificate of Formation for a Delaware LLC [3]. Delaware law sets the LLC annual tax at $300 [4]. An EIN from the IRS costs $0 [5]. The state business license fee sits in Title 30 and changes with the activity code you claim, so treat any blog number as stale until the Division of Revenue matches your description [1].
Insurance is the first real bill. I will not invent a Delaware premium. Carriers price height, chemicals, prior claims, and whether you ever leave the sidewalk. Get two quotes before you buy a second pole. A used car you already own beats a wrapped van in year one.
Gear is the second real bill. A water-fed pole, a small deionizing tank or resin vessel, a brush, and a hose run from a few hundred dollars to a couple thousand depending on how much you buy used. A trailer RO rig and a lift belong on a later tax return, not this one.
SBA tells new owners to write the startup number from actual vendor quotes, not a national template [11]. That advice fits this trade. Nobody publishes a clean Delaware survey of first-year window route cash. Here is the closest honest range. Solo, sidewalk only, car already paid for: roughly $1,500 to $8,000 before you pay yourself, with insurance as the swing factor. Buy a van, a lift, or a big RO skid and you leave that band fast.
Skip the “Delaware window license” line. That board does not exist. Budget the business license, the city license if the route sits in Wilmington, Dover, Newark, or another incorporated place, and the entity tax if you form the LLC.
Do not confuse this with replacing storefront glass. Glazing is a different trade, a different insurance class, and often a different municipal permit. This article is the cleaning route.
Do you need a license for storefront windows in Delaware?
Yes, you need a Delaware business license from the Division of Revenue if you conduct the business here. No, you do not need a statewide occupational license that says “window washer” on it. The Division of Revenue says most businesses operating in the state must obtain a business license and pay the license fee and gross receipts tax [1]. Title 30, Chapter 23 is the statute behind that [2].
No Delaware board tests squeegee work, water-fed poles, or pure-water systems. I checked the professional-regulation list the way I would for a client file. Cleaning storefront glass is not electrician work and it is not a statewide contractor class. Start installing glass and that becomes another conversation.
A city can still make you buy its license. Wilmington, Dover, Newark, and other municipalities run their own business-license desks. Unincorporated New Castle County, Kent, and Sussex leave you with just the state license. Confirm the city before you print door hangers.
Form an LLC and you also file with the Division of Corporations and keep a registered agent. That is entity paper, not a trade license. Stay a sole proprietor under your own name and you still need the Revenue license. Skipping the entity does not skip the state.
File the Revenue license under the closest service description they offer, then ask them to confirm the gross receipts category. Do not guess the code from a Facebook thread. A wrong code means the wrong tax rate later.
Federal work is thinner. The IRS EIN is free and you need it for the LLC, for a bank account in the company name, and if you hire [5]. OSHA is not a license. It is a duty once you have employees on a walking-working surface [8].
Here is the short version. State business license: yes. Statewide washer ticket: no. City license: maybe. Confirm with the Division of Revenue and the city clerk for the blocks you actually wash.
How long does storefront windows take in Delaware?
This question mixes three clocks. Forming the company can be fast. Getting the Revenue license runs on a timeline you confirm, not a promise I will invent. Building a paying route takes longer than either filing.
A Certificate of Formation is a short document. People file it online through the Division of Corporations. I will not quote a processing time. Those queues move. Check the Corporations site the week you file [3]. The IRS can issue an EIN during the online session when the application goes through [5].
The business license sits with the Division of Revenue. I will not invent a day count. Use their current application and status tools, and plan your first invoice after they tell you the license is active [1]. A city license adds another desk. Stack those. Do not assume they run in parallel unless the clerk says so.
The clean itself is short. A single-story shopfront with a door and a couple of sidelights is often a 15 to 45 minute stop once you know the glass. A strip center with 8 tenants is a morning. High glass from a lift is a different day and a different insurance conversation.
The route is the slow part. Cold walking a Pike Creek or Route 13 block fills a notebook before it fills a calendar. Give the paper two focused days and give the first 20 accounts several weeks of knocking. Anyone selling you a guaranteed book of Delaware stores is selling something else.
Winter is real here. Ice, road salt film, and early dark stretch a January day. Summer tourist glass in Dewey and Rehoboth packs the calendar if you already hold the accounts. None of that is a state processing time. It is weather and sales.
What filings make up the real Delaware paper path?
The real path is short. People overbuild it because they copy states that license contractors statewide. Delaware does not work that way for a sidewalk storefront route.
Start with the entity choice. Sole proprietor under your legal name, or a Delaware LLC. DBA paperwork only matters if you want a trade name. Then get the EIN if you formed the LLC, if you want a business bank account, or if you will have employees [5]. Then the Division of Revenue business license [1]. Then the city license if the work sits inside a city that bills one. Then insurance binders. Then you wash glass.
Here is the lookup table I actually use.
| Filing | Who bills it | Published cash | What you confirm |
|---|---|---|---|
| LLC Certificate of Formation | Division of Corporations | $90 [3] | Current fee schedule the week you file |
| LLC annual tax | Division of Corporations | $300 by statute [4] | Due date and how they want it paid |
| EIN | IRS | $0 [5] | That the responsible party is a real person |
| State business license | Division of Revenue | Set by Title 30 activity [1] [2] | Activity code and license fee |
| Gross receipts tax | Division of Revenue | Rate and exclusion by category [6] [7] | Current rate table, not a blog |
| City or town license | City finance desk | Local | Whether your stops sit in that city |
| Unemployment account | Department of Labor | Only if you have employees [14] | Employee count, not “helpers” you pretend are vendors |
Delaware’s own startup checklist lives on the state’s business steps page. Use it as a map, then open the agency that collects the money [13]. A checklist is not a license.
Keep a folder with the Revenue license, the Corporations filing stamp, the EIN letter, the insurance declarations page, and any city receipt. That folder is what a property manager asks for. Not a motivational invoice.
How much is a Delaware LLC versus staying a sole proprietor?
A Delaware LLC costs $90 to file if the published Corporations fee still reads that number the week you submit [3]. The annual tax is $300 under 6 Del. C. § 18-1107 [4]. You also pay a registered agent every year. That is a private fee. Shop it. I would not pay a premium brand just to say the agent sits on Rodney Square.
A sole proprietorship skips the $90 and the $300. You still get the Revenue license. You still pay gross receipts tax on the taxable receipts. You still buy insurance. You put your own name on the contract and on the claim.
I would form the LLC if a van, poles, and a route were going in the company and I wanted the bank account clean. I would stay a sole prop for a 90 day test if I was washing a handful of shops after another job and had almost no gear. That is a judgment call, not legal advice. StorefrontWash is an independent publisher, not a law firm.
People form Delaware LLCs for out-of-state holding companies all day. That is a different product. If you live in Newark or Smyrna and you wash local glass, you are a domestic operator who happens to use a famous filing office. You still owe the Revenue license because you are doing business in the state [1].
Franchise tax tables for corporations are a rabbit hole you do not need. Those are C corp and authorized-share math. An LLC paying the flat $300 is the usual small-route fact [4].
Does Delaware charge sales tax on storefront window work?
Delaware has no general state sales tax. You will not add 6 or 8 percent on a window-cleaning invoice the way a Pennsylvania or Maryland stop might. What you deal with instead is the gross receipts tax administered with the business license [1] [6].
Gross receipts tax is a tax on the receipts of the business, with rates and monthly exclusions that depend on the business category in Title 30, Chapter 29 [7]. I am not going to paste a rate. Those tables get amended. Pull the current category and exclusion from the Division of Revenue the month you open [6].
This trips people who move from a sales-tax state. They either forget to price GRT into the stop, or they illegally add a fake “sales tax” line. Do not invent a sales-tax line. If you want the tax covered, raise the clean price.
Local lodging or amusement taxes you see at the beach are not your problem on a storefront contract. Your problem is the license, GRT, and any city business tax the clerk names.
If a national account sends you a resale certificate, read it. Window cleaning is usually the taxable service on your side, not a resale of goods. When in doubt, ask Revenue, not the account’s AP clerk.
Which cities add their own license on top of the state?
Incorporated cities in Delaware often want their own business license when you operate inside the city. Wilmington is the one operators ask about first because so much storefront glass sits there. Dover and Newark are the next two. Beach towns get picky in season.
I will not invent a Wilmington fee or a Dover processing time. Those desks change forms. Call the city’s finance or licenses office and ask a blunt question. “I wash storefront glass on the sidewalk. Do I need a city business license if my LLC is already licensed by the state?” Write down the name of the person who answers.
If every stop is in unincorporated New Castle County, you may only hold the state license. Do not guess the city line from a Google pin. A shopping center can sit just inside a boundary.
A city license does not replace the Division of Revenue license [1]. It stacks. Same for a town contractor registration if you ever leave cleaning and start installing frames. Stay on the cleaning side and you stay out of most contractor queues.
License the city where the dense part of the route lives, then add a second city only after you have paying glass there. Paying three town halls for a route you have not sold yet is how people waste March.
What insurance and fall rules actually apply on a storefront route?
Liability insurance is not optional if you want property managers to let you on the glass. Auto insurance is not optional if you drive to the stop. Delaware motorists must carry the financial-responsibility coverage in Title 21 [15]. Workers’ compensation becomes a Title 19 problem the moment you have employees [10].
Buy a general liability policy that states window cleaning, not a generic handyman form that excludes height and chemicals. Ask the broker to write sidewalk, water-fed pole, and interior retail glass in the notes. If you later add a lift, call them before the lift hits the sidewalk.
OSHA is the rule people skip until someone climbs a ladder. The walking-working surfaces standard puts the fall line at 4 feet. The text is blunt: “the employer must ensure that each employee on a walking-working surface with an unprotected side or edge that is 4 feet (1.2 m) or more above a lower level is protected from falling by one or more of the following” [8]. That is 29 CFR 1910.28.
If you are truly solo with no employees, OSHA’s employer duties are a different analysis. Do not use that as a reason to stand on a two-story ledge. The glass will still put you in a hospital. Stay on the sidewalk with a pole for year one. Interior work on a step stool is enough excitement.
Personal fall protection systems, when you need them, live in 29 CFR 1910.140 [9]. That is harness and anchor territory. It is not a first-year strip-center kit.
Delaware workers’ compensation sits in Title 19, Chapter 23 [10]. Hire one helper and stop calling them a contractor out of habit. The IRS test for employee versus independent contractor is about control and independence, not what you print on the check memo [12]. Unemployment insurance registration follows real employees [14].
What should first-year equipment cost if you stay on the sidewalk?
Stay on the sidewalk and the kit is boring. That is a compliment. A water-fed pole, a brush head, a hose, a small DI or mixed-bed resin vessel, a refill plan for resin, a squeegee kit for interiors and doors, towels, a five-gallon bucket, and shoes you can actually walk in.
Used poles show up cheap. New carbon fiber gets spendy without making the glass any cleaner. Buy mid-grade and replace the brush before you replace the pole. Resin is a consumable. Budget it like soap, not like a capital asset.
StorefrontWash publishes a $149 one-time Pure-Water Pole Route Kit for people assembling that sidewalk setup. You can also piece the same class of gear from pool and farm suppliers. Either path beats a $12,000 trailer you store in a cousin’s yard.
A ladder is how people get hurt and how insurance gets interesting. If a second-story pane cannot be reached from the sidewalk, skip that account in year one or subcontract it to someone who already carries the height class. I mean that.
Vehicle cost is the sleeper. If the car is paid for, your startup number stays honest. If you “need” a new van for a route with 12 shops, you are buying a lifestyle. Put a liner in the hatch and go.
SBA’s startup-cost worksheet is useful here because it forces you to list the boring lines: deposits, phone, bookkeeping, and the first insurance installment [11]. Operators forget those and then say “equipment cost me nothing” while carrying a $900 binder on a card.
What do Delaware shop owners pay for a storefront clean?
Nobody has a good public data set on Delaware storefront window prices. Trade groups do not publish a county-by-county pane schedule. The honest statement is that owners pay by visit, by pane count, or by a monthly route rate, and the number moves with glass area, interior work, and how filthy the last contractor left the sills.
I would quote a small single-story shop as a flat stop, then write a monthly rate if they want weekly glass. I would not publish a fake “Wilmington average” and I would not copy a national franchise menu. Walk the glass. Count the doors. Look at the awning drips.
Interior glass (the vestibule, the display cubes) is where routes make money and where they get slow. Price it. Exterior-only water-fed work is faster and easier to stack on a block.
Beach-town independents will pay for reliability in July and forget you in February. State-office corridors and medical offices want a certificate of insurance more than they want a cheap first clean. Price the paperwork time into those accounts.
If you also price work in other states, read the local paper path first. storefront windows cost in Connecticut is the nearest comparison that still feels like the Mid-Atlantic. storefront windows cost in California is a heavier license climate and a bad template for Dover.
Do you need payroll accounts if you stay solo?
If you have no employees, you do not open a Delaware unemployment account and you do not run payroll withholding for staff you do not have [14]. You still pay your own income tax. You still file the business license and GRT on the schedule Revenue assigns [1] [6].
The minute a second person regularly washes glass under your direction, on your schedule, with your pole, you are in employee territory unless the facts truly show an independent business [12]. The IRS page on employee versus independent contractor is the federal test. Delaware unemployment follows real employment [14]. Workers’ compensation follows Title 19 when those people are employees [10].
I would not hire in month one. Subcontracting a high job to an already insured crew is cleaner than inventing a “1099 helper.” If you do hire, get the UI account, the withholding accounts, and the workers’ comp binder before the first shift.
An EIN is worth having once you form an LLC even if you never hire. Banks and 1099 clients ask for it. The IRS repeats that applying is a free service [5]. The same page is blunt: “Applying for an EIN is a free service offered by the Internal Revenue Service.” Do not pay a reseller for that number.
What would I skip, and what would I not cheap out on?
I would skip the lift, the new van, the embroidered shirts, the downtown virtual office, and any “done for you Delaware license” service that charges hundreds to stand in a line you can stand in yourself. I would skip bonding unless a specific property manager writes a bond amount into the vendor packet. Most shop owners never ask.
I would not skip the Revenue license [1]. I would not skip liability insurance. I would not skip a written scope that says exterior glass only, sidewalk only, no interior furniture moving. I would not skip photos of cracked panes before you touch them.
Registered agent: pay a cheap competent one, not a souvenir. Bookkeeping: a simple ledger beats a $200 month app you will not open. Resin: do not cheap out. Bad water leaves spots and you lose the account.
If you want a comparison for a cheaper, hotter market, storefront windows cost in Florida and storefront windows cost in Georgia show different climate and different municipal habits. storefront windows cost in Illinois has a heavier city-license culture than most of Kent County.
Confirm every variable fee the week you file. I am not the board. This site is not the board.
How does the Delaware paper path compare with other states?
Delaware is light on occupational theater and heavy on the business license plus gross receipts tax. That is the opposite of states that make you sit a contractor exam to wash a door. It is also why copied checklists from big states waste your week.
If you are pricing a move, read a real state page, not a roundup. storefront windows cost in Colorado and storefront windows cost in Arizona are dry-climate routes with different municipal stacks. storefront windows cost in Alabama is another light-occupational example people confuse with a full contractor state.
Use the Delaware steps page as your map, then open Corporations, Revenue, and the city [13]. If you want the paper checklist in one place, the kit at /start is optional. The state URLs above are the source of truth.
No approval timeline in this article is a promise. Boards move. Fees get amended. Pull the live schedule.
Frequently asked questions
Do you need a license for storefront windows in Delaware?
You need a Delaware business license from the Division of Revenue to operate the business. You do not need a statewide occupational window-washer license. Some cities add their own business license. Confirm the activity code with Revenue and ask the city clerk if your stops sit inside city limits.
How much does storefront windows cost in Delaware?
State paper is small if you form an LLC: $90 to file and $300 a year, plus a Revenue license fee that you confirm by activity code. An EIN is $0. Real first-year cash is insurance, a car you already have, and sidewalk gear. Solo sidewalk routes often land somewhere around $1,500 to $8,000 before pay. Nobody publishes a solid Delaware survey.
How long does storefront windows take in Delaware?
Entity filings can be quick. I will not invent Division of Revenue or city processing times. Confirm those with the desk that issues the license. A small shopfront clean often takes 15 to 45 minutes. Building a paying route takes weeks of walking blocks, not a weekend of forms.
Is window cleaning a licensed trade with a Delaware board?
No statewide washer or glazier-cleaner board sits over sidewalk storefront work. Title 30 still expects a business license for the occupation you actually run. If you switch from cleaning to installing glass, ask the city about contractor registration before you cut a frame.
Does Delaware charge sales tax on window cleaning?
Delaware has no general sales tax to add on the invoice. You still deal with gross receipts tax through the Division of Revenue, with a rate and exclusion that depend on your category. Do not invent a sales-tax line. Price the GRT into the stop and pull the current table from Revenue.
How much is a Delaware LLC for this kind of route?
The Division of Corporations publishes a $90 Certificate of Formation fee. Statute sets the LLC annual tax at $300. You also pay a registered agent on the private market. A sole proprietor skips those two Corporations bills and still needs the Revenue license.
Do I need workers compensation as a solo operator?
Title 19, Chapter 23 is the workers’ compensation statute. It matters once you have employees. If you are truly solo, confirm your own status with a Delaware-knowledgeable carrier before you assume you are out. The moment you direct a helper on your schedule with your tools, revisit that answer.
Do I need a contractor license to wash storefront glass?
Not at the state level for ordinary sidewalk cleaning. Delaware does not run a statewide general-contractor exam for this work. A city can still require a local business license. Installation, frames, and glass replacement are a different job. Keep the written scope on cleaning.
Can I use a water-fed pole from the sidewalk without a lift permit?
Sidewalk pole work on first-story glass is the normal first-year method. A lift or blocked sidewalk can trigger city right-of-way rules. Ask the city before you park equipment on a public walk. OSHA’s 4 foot fall rule applies to employees on unprotected edges. Stay on the ground in year one.
Do I need an EIN if I have no employees?
The IRS issues an EIN for free. You need one for an LLC bank account in the company name, and you need one when you hire. A sole proprietor with no employees can often use a Social Security number, but many commercial clients still ask for an EIN. Do not pay a third party for the number.
When is the Delaware LLC tax due?
Statute sets the amount at $300. The due date and payment portal live with the Division of Corporations and can be amended. Confirm the current due date on the Corporations pay-taxes page the year you are in, and calendar a reminder a month early so you are not guessing in June.
Does Wilmington require its own license on top of the state?
Wilmington and other incorporated cities often require a local business license when you operate there. I will not quote their fee. Call the city’s license desk, describe sidewalk storefront cleaning, and ask if the state Revenue license is enough. Keep a note of the answer and the date.
