How to start a power washing 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 flatwork holds construction dust, road film, and the stain winter leaves on concrete. Highlands and Capitol Hill are older and tighter. Aurora, Lakewood, and Arvada are driveway volume. This is not a mildew market in the Florida sense. Say that. New arrivals want the concrete washed the month they move in. If you do not cross a particular beltway, write it down, and ask where the water is allowed to run.
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 Driveways, walks, and house washes on a defined Denver map, without a humid-climate script.
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.

Many one-truck washing routes start as a sole proprietorship. An LLC is a reasonable filing once you are taking deposits, hiring, or putting the insurance in a company name. The filing does not decide the license and it does not decide where the water may go. Read the contractor board and the city separately. Ask an accountant if you are paying helpers and still thinking of them as a favor. This page is not legal 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 for a washing classification and any dollar threshold on that page. Confirm a city business license either way. If the work is a lead renovation, EPA's RRP page requires containment so wastewater stays in the work area, and it tells you to ask the local water authority about disposal. On a construction site covered by EPA's 2022 Construction General Permit, building washdown and pavement wash water have to meet that permit, including no soaps, solvents, or detergents for those discharges. A residential route that is not one of those jobs is still a city storm-drain question. Ask before you send water to the street.
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 power washer 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 wand points at someone else's house. Tell the insurer you pressure-wash, and name the surfaces, so a claim is not denied for work you did not disclose. Water forced behind siding or into an open window is the ordinary loss. Ask whether the policy speaks to that. Commercial auto for the truck and trailer. Workers' compensation before a second person is handling the gun or driving the rig. A property manager will ask for the certificate before the first driveway.
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.
Fuel, tips, and the replacement hose should come out of a business account, not a personal card you sort out in April. Deposits on a house wash and the small driveway tickets both go in the same account, with the address written down. Set tax money aside the day a larger job pays.
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
Write three prices before you need them: a driveway or flatwork visit, a house wash, and the surface you will not do. Wood, soft stone, and roofs are where a single 'per square foot' number goes wrong. Include the time to control the water. A quote that assumes the runoff can run to the street is incomplete until the city has said so.
Mildew, dust, and salt stain are different films and different times. A price copied from another climate will be wrong. Adjust the three numbers after ten real jobs, and do not promise the film will never come back.
intense sun, hail, big daily temperature swings, and a dry cold that freezes pipes left in exterior walls brick bungalows, newer suburban tracts, and attics and roofs that take a beating from hail and UV That is why a price copied from another metro will miss. Driveways, walks, and house washes on a defined Denver map, without a humid-climate script.
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.
08Open the profile, the reviews, and the site
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.
Ask for a review after a clean job, and ask them to mention the neighborhood and the task. A review that says the work and Lakewood helps the next search. A review that says 'great service' does not.
Google Business Profile with photos of driveways and siding you have actually washed in this climate, and a service area made of towns you drive. Reviews should name the neighborhood and the surface. The website splits flatwork from house washes, says which surfaces you refuse, and says you ask the city about wash water. The form asks for the surface and the size. ServiceBase publishes that page and keeps the requests. It does not make the discharge legal.
When the name and the phone are real, create the free power washing site with Denver already filled in. Quote requests land in your list. The site does not replace City and County of Denver permits.

Can I publish a power washing 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 power washer and Denver filled in so you are not retyping them.
