Quick answer: In Knoxville, driveway and walkway cleaning typically runs $100 to $300, full house siding washes range from $200 to $600, deck cleaning falls between $150 and $400, and roof soft-washing usually costs $300 to $700 depending on size and pitch. Actual pricing depends on square footage, surface condition, and whether soft-washing is required.
Rather than a single flat rate, most pressure washing companies price by the specific surface being cleaned, since each one involves different equipment, cleaning solutions, and time. Below is a breakdown of what Knoxville homeowners can typically expect for the most commonly requested services.
Driveway and Walkway Cleaning
Concrete driveways and walkways are among the most frequently requested pressure washing services, largely because they show dirt, oil stains, and pollen buildup clearly and sit at the front of the property. A standard single-car driveway typically falls between $100 and $175, while larger double driveways or those with a connected walkway can range from $200 to $300.
Pricing rises when a driveway has heavy oil or rust staining, since these often require a degreasing pretreatment before the surface is cleaned. Cracked or pitted concrete can also take longer to clean thoroughly, as dirt tends to settle into the uneven surface.
Siding Cleaning
Because most Knoxville homes use vinyl, fiber cement, or painted wood siding, this service is typically performed using soft-washing rather than high-pressure cleaning to avoid forcing water behind panels or damaging paint. A full exterior wash for a single-story home generally runs $200 to $350, while two-story homes range from $350 to $600 due to the additional height, surface area, and equipment needed to reach upper sections safely.
Homes with significant algae streaking — common on north-facing walls or heavily shaded lots — may fall toward the higher end of that range, since the soft-wash solution needs time to break down organic growth before rinsing.
Deck and Fence Cleaning
Wood decks and fences require careful pressure calibration to avoid splintering or gouging the surface, which makes this one of the more technique-sensitive services. A standard deck cleaning typically costs $150 to $300, depending on square footage and whether the wood shows heavy mildew or gray weathering from sun exposure. Fence cleaning is often priced similarly, with larger privacy fences on the higher end of the range.
Some homeowners choose to pair deck cleaning with a wood brightening treatment or sealant application afterward, which is typically quoted as a separate add-on rather than included in the base cleaning price.
Roof Soft-Washing
Roof cleaning is one of the more specialized services, both because of the safety considerations involved and because asphalt shingles require a gentler approach than concrete or siding. Soft-washing — using a low-pressure application of cleaning solution rather than direct high-pressure spraying — is the standard method for removing the dark streaking commonly caused by algae growth, particularly on shaded or north-facing roof sections.
Pricing typically ranges from $300 to $700 depending on roof size, pitch, and accessibility. Steeper roofs or those with multiple levels may cost more due to the additional safety equipment and time required.
Patios, Pool Decks, and Outdoor Living Areas
Stone, brick, and paver patios are usually priced similarly to driveways on a per-square-foot basis, though pavers with sand-filled joints sometimes take longer to clean thoroughly without disturbing the joint material. Pool deck cleaning follows a similar pricing structure, typically $150 to $350 depending on size, with attention paid to non-slip coatings that some pool decks have applied.
Commercial and Multi-Surface Properties
Commercial properties, such as storefronts, parking lots, or multi-unit buildings, are generally priced differently than residential jobs due to larger square footage and different scheduling needs, often outside business hours. These quotes are typically calculated individually after a site assessment rather than using standard residential pricing ranges. For a look at what specifically influences pricing across job types.
Bundling Services for a Lower Combined Rate
Homeowners who need more than one surface cleaned — for example, a driveway, walkway, and siding wash all in the same visit — often see a lower combined rate than if each service were scheduled separately. This is largely due to reduced setup and travel time for the crew. If you’re planning a full exterior refresh, it’s worth asking for a bundled quote rather than pricing each surface individually.

Frequently Asked Questions
Why does roof cleaning cost more than driveway cleaning? Roof cleaning requires soft-washing equipment, safety precautions for working at height, and often a longer application time for the cleaning solution to break down algae, all of which add to labor time compared with a ground-level driveway cleaning.
Is siding cleaning priced the same for one-story and two-story homes? No. Two-story homes typically cost more because they have more total surface area and require additional equipment and time to safely reach and clean the upper sections.
Can I get a lower price by booking multiple services together? Often, yes. Scheduling a driveway, siding, and deck cleaning in a single visit usually costs less combined than booking each one separately, since it reduces the crew’s setup and travel time between jobs.
