How to start a window cleaning business in Denver, CO
This is not legal, tax, or insurance advice. Read the official pages linked here. Partner offers are optional and labeled.
Denver glass takes construction dust, a dry fine dirt, and hard-water spots. Highlands and Capitol Hill are older and more walkable. Aurora, Lakewood, and Arvada are route volume. Sun at altitude shows every streak. New arrivals book a window cleaner the same month they get keys. If your route stops at a beltway, name it. Hail damage is a glass company, not a wash.
brick bungalows, newer suburban tracts, and attics and roofs that take a beating from hail and UV intense sun, hail, big daily temperature swings, and a dry cold that freezes pipes left in exterior walls Exterior routes, interior add-ons, and a Denver map that does not pretend to be the whole Front Range.
Start the route in Highlands, Capitol Hill, and Aurora. Add Lakewood and Arvada when you can reach them the same day. After a hailstorm the inbox fills with out-of-town crews. A local page wins by showing a real address in the metro and photos of local roofs.
The Colorado guide has the filing office. This page is the local version: what the first jobs are, which permit counter to call, and how to price a day here.
Some boxes are labeled Partner. ServiceBase has not joined those programs. The links go to each company's own homepage, not a tracking link. If a program later approves us, the address will change and we may earn a commission. You can file, insure, and bank anywhere. Official government links are not partner links. Nothing on this page is a discount code.

Keep the checklist on your account
The guide stays public. An account saves your state, city, and trade, and lets you mark each filing as you go. The advertising credit is reserved when you register. It can be spent after the free website is live.
A lot of window routes start as a sole proprietorship because the owner is the person on the pole. That can be you, under your own name, with no formation filing. An LLC is a state filing and a separate company on paper. It does not license you, and it does not replace insurance. Form the LLC when you hire, when a storefront wants the company on a certificate, or when you want the bank account in the business name. If you are unsure, ask an accountant before you pay a filing fee. This page is not that advice.
We do not have a filing fee for Colorado that we are willing to print. Use the SBA lookup, choose Colorado, and read the fee on the state office's own page. Sole proprietors who operate under their own name often skip this filing. Confirm that on the same site.
If your customers are in Denver, the registered-agent address still has to satisfy Colorado. Read the filing office's rule. A neighbor's kitchen table is not always an acceptable address.
An employer identification number is the business tax ID. The IRS issues it online at no charge and says you never have to pay a company to get one. If you form an LLC, file with the state first. The IRS says an EIN application can stall when the state filing is not done. A sole proprietor can often start with a Social Security number and get an EIN when a bank or a hire requires it.
Apply on the IRS page if you want the number yourself. LegalZoom, the partner beside this step, can request it while they form the company. That service is optional. The IRS fee is still zero either way.
Read the contractor board far enough to see whether window cleaning is on it, including any project-cost threshold printed there. Then get the city business license and the tax permit the revenue department describes. Adding pressure washing or building repairs is a second read, not a free extra.
State page: Colorado Division of Professions and Occupations. This office licenses specific professions, including electrical and plumbing. It is not one license for every home-service business. Check the city as well.
City and County of Denver permits is the local counter for work in Denver. We are naming that office, not linking a fee schedule we have not read. Call them or open the city's own site and ask what a new window cleaner has to register before the first job in Capitol Hill.
The Colorado guide repeats the board link and tells you what we could not verify. Read it before you pay a filing service.
General liability before the pole goes onto someone else's glass. Tell the insurer you do ladders and, if it is true, that you step inside for interior panes. A broken pane and a soaked sill are the claims. Commercial auto if the car or van is how you move between stops, because a personal policy often excludes business use. If anyone else is on a ladder or carrying water, ask about workers' compensation before they start. Do not copy a headcount from another state. Keep a certificate you can send the same day a property manager asks.
Workers' compensation is a state program. Before anyone works with you, including a friend, ask an insurer and the state labor office whether you must carry it. This guide does not quote a headcount, because those rules differ and the state page is the source. The SBA page describes the common policies. It does not sell them. Buy the policy before you work in a house in Denver.
Deposit route money into a business checking account the same week. Window stops pay small amounts, and those amounts vanish in a personal account. Note which address paid. Set tax money aside every Friday, before a good week feels like spending money.
The bank will usually ask for your ID, the EIN or your Social Security number, and the formation papers if you filed an LLC. A checking account and a habit of setting tax money aside are enough at the start.
07Price a day in Denver
Price the visit from stories, panes or a simple house size, interior versus exterior, and screens. Hard-water removal is its own line if you offer it. A ground-floor exterior and a second-story interior are different jobs. Write both numbers down before you need them in a driveway.
Pollen, salt, construction dust, and stairs change the time. A price copied from an empty suburban photo will lose money in a walk-up. Adjust the numbers after you have timed ten real stops, and tell recurring customers when the price changes.

Write the price you want for the common job in Highlands and the price you want for a far stop in Arvada. If the second number is not worth the drive, leave Arvada off the service area.

Claim the Google Business Profile for Denver, CO. Set hours you answer. The service area should list Highlands, Capitol Hill, and Aurora if those are real stops, and it should leave off towns you will not drive.

Claim the Google Business Profile in the business name, with hours you actually answer and a service area made of towns you drive. Ask for a review after a clean visit, and ask the customer to name the neighborhood and whether it was exterior, interior, or a storefront.

Can I publish a window cleaning site before the LLC is approved?
You can draft it. Put it in public under the name you will actually use, with the phone you answer. If the state requires the license before you advertise the work, wait. The free ServiceBase site does not file the company. Signup can open with window cleaner and Denver filled in so you are not retyping them.
