How Much Does Pressure Washing Cost in Colorado? (2026 Price Guide) Rates by Surface and Season

Pressure washing cost in Colorado for 2026: prices by surface, magnesium chloride removal, stucco soft washing, season timing, sealing, and how to hire safely.

How Much Does Pressure Washing Cost in Colorado? (2026 Price Guide) Rates by Surface and Season

Pressure washing cost in Colorado runs $0.15 to $0.40 per square foot in 2026, which puts a typical house wash at $275 to $650 and a two car driveway at $150 to $375. Most companies set a minimum of $200 to $275, so bundling several surfaces into one visit is how you get value out of the trip.

Colorado adds two variables that most states do not. The season is short, roughly April through October along the Front Range and shorter in the mountains, and magnesium chloride de-icer sprayed on highways all winter leaves a residue on driveways, garage doors, and lower siding that plain water does not remove.

Prices by Surface

House exteriors are usually soft washed rather than pressure washed, meaning low pressure plus a cleaning solution. A single story ranch runs $250 to $450, a two story house runs $350 to $700, and larger homes in Cherry Hills, Castle Pines, or west Boulder run $600 to $1,200.

Concrete driveways run $0.15 to $0.35 per square foot. A standard 600 square foot driveway lands at $110 to $210, and adding the sidewalk and front walkway usually costs another $60 to $150.

Wood decks are priced higher because they take more care. Cleaning alone runs $200 to $500, and cleaning plus a stain or sealer application runs $2.50 to $5 per square foot, so a 400 square foot deck lands between $1,000 and $2,000 for the full treatment.

Composite decking cleans faster and cheaper at $150 to $350 for a typical deck. It also requires low pressure, since high pressure permanently scars the surface.

Patios, walkways, and pool decks fall in the same range as driveways. Stamped and colored concrete needs a lower pressure approach plus resealing afterward at $0.80 to $1.75 per square foot.

Fences run $1.50 to $3.50 per linear foot for cleaning, and cedar fences that are being cleaned before staining should be scheduled with the staining work in mind.

Stucco Needs a Different Approach

A large share of Colorado homes have stucco or synthetic stucco exteriors, especially in Denver, Colorado Springs, and the newer suburbs. Stucco cannot take high pressure without cracking the finish coat or driving water behind the wall.

The correct method is a soft wash with a mild detergent and a thorough rinse. Pricing is similar to siding at $300 to $700 for most homes, and any contractor who wants to bring 3,000 psi to a stucco wall should be sent away.

Existing cracks are the risk. A good contractor walks the exterior first and points out cracks and failed caulking at windows, because water forced into those openings is how a cleaning job becomes a repair job.

How Contractors Build the Number

Square footage is the starting point, then three multipliers get applied. Height is the first, because a two or three story home in Highlands Ranch or Erie means extension equipment, ladders, or a lift.

Condition is the second. A driveway washed last year cleans in one pass, and one that has not been touched in six years takes two passes plus pre-treatment, which can double the labor.

Water access is the third and the one homeowners forget. Contractors need a working spigot with decent flow, and properties on wells or with frozen outdoor spigots require the crew to bring a tank, which adds $50 to $150.

Distance rounds it out. Mountain and rural addresses often carry a travel charge of $50 to $150, and some Front Range companies simply will not go above a certain elevation.

What Colorado Weather Leaves Behind

Magnesium chloride is the state's signature cleaning problem. CDOT and local agencies apply it as a liquid de-icer, and vehicles carry it into driveways where it leaves a white haze and works into the concrete surface.

Removing it requires a dedicated de-icer neutralizer and a proper dwell time. A basic water blast makes it look better for a week and then the haze returns, which is why the cheapest quote often disappoints.

Sun and altitude are the second factor. UV exposure at 5,280 feet and higher breaks down paint, sealers, and wood finishes faster than at sea level, so surfaces need cleaning and resealing on a shorter cycle than the manufacturer's label suggests.

Hail leaves gutters and roofs full of granules and grit after every summer season. Gutter cleaning is often bundled with a house wash at $125 to $300 for a typical home, and gutter face brightening to remove tiger striping is an extra $75 to $200.

Wildfire smoke and ash coat exteriors during bad fire seasons. Washing that off before it sits through a winter protects paint and is a common late-season booking in the foothills communities.

Timing Your Job in a Short Season

The Front Range washing season opens in April and closes in late October. Freezing temperatures make the work unsafe and can damage equipment, and water left on concrete overnight in a freeze cycle causes spalling.

Mountain communities including Summit, Eagle, and Grand counties run a shorter window from late May into September. Contractors there book out further, and a homeowner who calls in July may wait a month.

Spring is the busiest booking period statewide, so calling in March for an April or May appointment gets you a better price and a better crew. September is the quiet month and often the best value.

Watering restrictions rarely stop this work. Most Front Range utilities exempt or allow pressure washing, though a few communities restrict it during severe drought stages, so check with your water provider if a stage restriction is in effect.

Hiring a Contractor Who Will Not Damage Your House

Colorado does not issue a statewide license for pressure washing. Some municipalities require a general contractor or business license, and that varies by city, so ask what applies where you live.

Insurance is the check that matters. Ask for a certificate showing general liability of at least $1 million and confirm it covers water damage, because the common claim in this trade is water driven into a wall, a window, or a soffit.

Ask what pressure and what chemistry they will use on each surface. A contractor with a real answer, different for stucco, wood, concrete, and painted siding, knows the work; one who says they just turn it up until it is clean does not.

Ask about water source and reclamation. Some Colorado municipalities require wash water containment on driveways and commercial surfaces to keep runoff out of storm drains, and a professional will know the local rule.

Get the scope in writing including which surfaces, what square footage, and whether sealing is included. Comparing several pressure washing companies in your area on written scope keeps the bids honest.

Sealing, Frequency, and Getting Your Money's Worth

Concrete sealing after a wash runs $0.50 to $1.25 per square foot and is worth it in this climate. Sealed concrete resists de-icer, freeze-thaw damage, and staining, and it should be redone every two to four years at Colorado elevations.

Wood decks need cleaning annually and sealing every two to three years. A deck that goes five years without attention usually needs sanding before it can be sealed, which doubles the project cost.

House washing every 12 to 24 months is the norm along the Front Range. North-facing walls and shaded areas grow algae faster and may need a shorter interval.

Bundling is where the savings sit. A house wash, driveway, walkways, and gutters booked together typically runs 15 to 25 percent less than the same services booked separately across a season. More Colorado home service pricing guides are on our home services blog.

Common Questions About Colorado Pressure Washing Prices

How much does it cost to pressure wash a 2,000 square foot house?

Expect $325 to $650 for a soft wash of the exterior, depending on stories, siding type, and access. Adding gutters and a driveway to the same visit typically brings the total to $500 to $900.

Will pressure washing remove magnesium chloride stains?

With the right neutralizing product and dwell time, most of it comes off. Concrete that has absorbed de-icer over many winters may keep a faint haze, and sealing afterward prevents it from returning.

Can pressure washing damage my siding?

Yes, if the wrong pressure is used. Vinyl, stucco, wood, and fiber cement each need different settings, and forcing water upward under lap siding is the most common way a job causes hidden damage.

When should I schedule pressure washing in Colorado?

April through June for spring cleanup, or September for the best availability and pricing. Avoid booking within a week of a hard freeze forecast, since wet concrete and freezing nights do not mix.

Is soft washing better than pressure washing?

For siding, stucco, roofs, and painted surfaces, yes. High pressure belongs on concrete, brick, and hard masonry, and even there a skilled operator uses a surface cleaner rather than a narrow wand to avoid striping.
