Pressure Washing in Denver, CO

Pressure Washing in Denver means working in a city where rinse water has a short trip to a river. Denver's storm system collects runoff through almost 24,000 inlets and about 800 miles of storm main pipe, then releases it through more than 600 outfalls into Cherry Creek and the South Platte. The city points out that this runoff gets no treatment at a wastewater plant along the way. So before any water touches a driveway or storefront, we look at where it would run and plan around the nearest inlet.

Denver Water's drought rules come first

Denver Water declared a Stage 1 drought on March 25, 2026, and its Board added tighter measures in Resolution #002a-2026, effective October 1, 2026, until the Board acts again. As the resolution reads, individuals may not power wash except for immediate health or safety reasons. Commercial enterprises for which cleaning with water is an essential part of the business may power wash only as necessary, and they must clean without water first, use only high-efficiency equipment and make sure water is not wasted. Denver Water's drought FAQ also states that routine or cosmetic power washing is not permitted after September 30. For a Denver Water customer, that means a purely cosmetic house or driveway wash may not be allowed right now. How the rules apply to a specific property is Denver Water's call, so confirm with them if you are unsure.

What we can still help with

While the restrictions are in place, a Denver job is planned around the rules rather than around appearance alone:

• Gutter clean-outs and debris removal, done by hand without washing
• Dry sweeping, scraping and blowing off walks, patios and storefront entries before any water is considered
• Cleaning where there is an immediate health or safety reason, with the reason written into the quote so you can confirm it fits the rules
• Planning and quoting full exterior washes now so they can be scheduled once Denver Water lifts or eases the restrictions

Hail, sun and a dry climate

Denver sits at an official elevation of 5,280 feet and soaks up roughly 3,100 hours of sunshine a year, with most of its precipitation arriving between April and August. That mix is hard on exteriors. Strong UV chalks paint and fades vinyl, summer thunderstorms leave grit and torn leaves plastered to walls, and hail can leave siding, gutters and fences scuffed and grimy even when nothing is broken. When washing is permitted again, a gentle soft wash shows you what shape the surfaces are really in.

Rentals, duplexes and shared walls

Census numbers put Denver's owner-occupied rate at 48.8%, so a large share of homes here are rented. If you own or manage a rental, a duplex or a small apartment building, we can work around tenant schedules, list notice dates in the written quote and handle shared walkways and entries in sections so access stays open.

How we handle the water

When water use is allowed, we keep pressure low on siding and roofs, cover plants, protect windows and keep wash water away from street inlets. Depending on the site, that can mean temporary inlet covers or berms, vacuuming up rinse water, or steering it onto turf or gravel to soak in. Stormwater requirements differ by property type and can change; the City and County of Denver is the authority to ask about a specific address.

Timing and quotes

Denver's average window for measurable snow runs from about October 17 to April 27, and washing needs surfaces and air above freezing. Early fall, after the summer hail and thunderstorm season, and mild stretches in spring are the easiest times for exterior cleaning, subject to whatever water-use rules are in effect then. Text us a few photos or call (720) 419-1995. We look at the surfaces, ask about access and your water provider, and put the scope and price in writing before any work starts.
