| Quick answer: Most Knoxville homeowners spend between $150 and $900 on a typical pressure washing job, depending on the surface and how big it is. A standard house wash runs about $450 to $900, with the average landing near $550, while driveways and concrete usually fall between $150 and $750. The only way to get your exact number is a free estimate, and we can usually get one to you the same day. |
Pressure washing prices in Knoxville aren’t one flat number, and any company that gives you a firm price over the phone without knowing your home is guessing. What you pay depends on the surface, its size, and how much buildup it’s carrying.
Knoxville makes that buildup worse than most places. Our humidity, red clay soil, and heavy tree cover let algae, mildew, and clay stains take hold fast, especially on shaded north and east walls. We’ve been cleaning homes around Knoxville and Farragut for more than 18 years, so the ranges below come from real jobs we quote every week, not a national calculator.
Pressure Washing Prices in Knoxville by Surface
We price most work by the square foot for houses, roofs, and concrete, by the linear foot for gutters, and per window for glass. That’s a fairer way to quote than a flat hourly rate, because it reflects the actual surface instead of how fast a crew happens to move.
Here’s what our common services typically run for Knoxville homes:
| Service | Typical Price Range | Average Job | How We Price It | Time on Site |
|---|---|---|---|---|
| House washing (soft wash) | $450 – $900 | ~$550 | Per square foot; vinyl costs less than stucco | 1 – 3 hours |
| Roof cleaning (soft wash) | $500 – $1,500 | ~$750 | Per square foot; $500 minimum | 2 – 4 hours |
| Driveway / concrete / patio | $150 – $750 | Varies by size | Per square foot; pavers cost more than concrete | ~1 hour |
| Gutter cleaning | $150 – $600 | ~$250 | Per linear foot; access and height matter | ~1 hour |
| Window cleaning | $150 – $650 | ~$200 | Per window; French panes cost more | 1 – 4 hours |
| Composite deck cleaning | $100 – $200 | Varies by size | Per square foot | 30 min – 1 hour |
A few oversized jobs run past these ranges. We once cleaned a driveway that came in at $1,200 because of its size. Most homes, though, land right inside the numbers above.
Two of these services have enough going on to deserve their own deep dives. If you want the full picture on house washing or roof cleaning, those pages walk through exactly what we do. Roof pricing in particular has more moving parts than we can fit here, so we put together a separate full roof cleaning cost breakdown for that.
What Affects Your Pressure Washing Cost
Size is the biggest factor on every surface. A larger home, longer driveway, or taller roof simply takes more solution, more time, and more setup. Nationally, house washing runs roughly $0.10 to $0.50 per square foot, and our Knoxville pricing sits comfortably inside that range.
After size, a handful of things move the number up or down:
- Surface and material. Vinyl siding cleans faster and costs less than stucco. Concrete costs less than pavers. French-pane windows take longer than plain glass because each small pane gets cleaned on its own.
- Height and access. Two-story homes and hillside lots need ladders and extra safety setup. A lot of West Knoxville and Farragut homes are two stories on sloped ground, which adds time to the job.
- Condition. Heavy red clay staining, oil spots, or years of algae need pre-treatment and dwell time before anything rinses clean. Red clay is a Knoxville specialty, and it clings to driveways and lower siding in a way a garden hose will never touch.
- The job minimum. Small jobs still carry a floor. Loading equipment, driving out, and using water and solution costs the same whether the surface is big or small, so a minimum keeps us able to show up for smaller projects.
Pressure Washing vs Soft Washing (and Why It Changes the Price)
Not every surface gets the same pressure, and that choice affects both the result and the price. Roofs and siding get a soft wash, which uses low pressure and a cleaning solution that does the real work. Concrete gets moderate pressure because it can take it.
Our house soft wash follows a set process. We pre-wet the plants, apply a solution of bleach, soap, and water at low pressure, let it dwell for several minutes, rinse the surface, then rinse the plants again. The solution kills the algae and mildew at the source, so it stays gone longer than a quick blast of high pressure would manage.
Roofs never get blasted. High pressure strips the protective granules off asphalt shingles, and the Asphalt Roofing Manufacturers Association is clear that you should never use a pressure washer on a shingle roof. We follow their low-pressure method, working from a ladder to protect both the shingles and your roof warranty. If you want the full comparison, we break it down in our guide on soft wash vs pressure wash for roofs.
Soft washing also uses very little water, and our solutions are biodegradable and safe for pets and plants once handled correctly. During a roof cleaning, one technician runs the roof while another stays on the ground protecting your landscaping the whole time.
How to Lower Your Pressure Washing Cost in Knoxville
Bundling is the easiest way to save. When you combine a house wash with a driveway, gutters, or windows in one visit, we only load up and drive out once, and we pass part of that savings on through a multi-service discount. The exact amount depends on which services you combine, so there’s no fixed percentage, but it’s a real cut compared to booking each job separately. If you’re already scheduling a house wash, adding window cleaning to the same trip is an easy win.
Staying on a schedule also keeps costs down. In Knoxville’s climate, an annual cleaning stops buildup before it turns into the kind of heavy staining that takes extra treatment to remove. Homes under heavy tree cover or on shaded sides may want a cleaning every six months, especially after the spring pollen wave coats everything in yellow.
Repeat customers get a discount too. The longer we work with a home, the easier it is to keep it looking right without a heavy clean each time.

Frequently Asked Questions
Is pressure washing priced by the hour or by the square foot in Knoxville?
We price by the square foot for houses, roofs, and concrete, by the linear foot for gutters, and per window for glass. Square-foot pricing gives you a fairer quote than an hourly rate because it’s tied to the actual surface, not to how quickly a crew works.
Why is there a minimum charge?
Even a small job means loading equipment, driving to your property, and using water and cleaning solution. A job minimum covers that setup so we can take on smaller projects without losing money on the trip.
Does a two-story house cost more to wash?
Usually, yes. Second-story siding and steep or hillside lots need ladders and extra safety setup, which adds time to the job and a little to the price. Plenty of Knoxville homes fall into this category, so it’s a common part of our quotes.
How often should I pressure wash my house in Knoxville?
About once a year for most homes. If yours sits under heavy tree cover or on a shaded north or east side, every six months keeps algae and pollen from settling in. Roofs run on a slightly different schedule, which we cover in our guide on how often to clean your roof.
Does pressure washing damage siding or roofing?
Not when the method matches the surface. We soft wash roofs and siding at low pressure so the cleaning solution does the work, which protects shingles, paint, and window seals. Damage usually happens when someone uses high pressure on a surface that can’t handle it.
