If you live in Manassas, you have probably watched green film creep across the north side of the house or noticed the driveway turning gray. The next question is always the same: what is this going to cost?
The typical power washing cost in Manassas for a full house wash is $400 to $800. We price house washing by the size of the home and how much buildup there is, so a smaller townhome lands near the low end and a large colonial with heavy algae lands near the top.
Below is how we price every service, what moves a quote up or down, and how to get an exact number. If you’d rather skip the math, our house washing service starts with a free, no-pressure quote.
Typical Prices in Manassas
Here is how we price each service in 2026. Every home is measured, so the only exact number is your free quote.
| Service | How we price it | Typical range |
|---|---|---|
| House washing (soft wash) | By the size of the home and the buildup | $400 to $800 for most homes |
| Roof cleaning (soft wash) | By roof size, pitch and buildup | Quoted per job |
| Gutter cleaning | By the length of the gutter run | Quoted per job |
| Window cleaning | By window count, with a discount when added to a house wash | Quoted per job |
| Pressure washing (driveways, patios, decks, walkways) | By surface size and condition | Quoted per job |
Time on site is usually 2 to 4 hours for a house wash or roof, up to 2 hours for gutters, and 1 to 3 hours for concrete.
Our minimum for a visit is about $250, which is why most homeowners bundle two or three services. Once the siding is bright again, a dull driveway or cloudy windows stand out, so pairing them in one visit usually makes sense.
What Changes the Price
Three things move a quote more than anything else.
- Size. More siding, roof or gutter means more time and more cleaning solution.
- Buildup. A home that has gone three or four years without a wash needs more dwell time and a second pass in shaded areas.
- Access. Steep roofs, three-story walls and tight lot lines take extra setup and safety work.
In Manassas we also see a lot of red clay splash along foundations and driveways. It comes off, but it takes more time than ordinary dirt, so heavily stained areas are noted on the quote.
Power Washing Cost in Manassas by Home Type
Manassas has every kind of home, from townhomes in Georgetown South to larger colonials around Yorkshire and Lake Jackson, plus the older houses near Historic Old Town. Here is roughly where each lands for a house wash.
| Home type | What usually drives the price |
|---|---|
| Townhome or end unit | Less siding, so most land near the bottom of the $400 to $800 range |
| Two-story single-family | The most common job; usually mid-range |
| Large colonial or three-story | More wall area and height; often near the top of the range |
| Older home with wood trim | Extra care around painted trim and older windows |
Measuring every home keeps it fair. Two homes on the same street can land at different prices because one has more siding or a lot more algae on the north side.
Why the Cheapest Quote Can Cost More
A low price sometimes means a crew is skipping steps. The most common shortcuts are no plant protection, high pressure on siding instead of a soft wash, and no insurance. Any of those can turn a $300 savings into a repair bill for dented siding, stripped paint or burned shrubs.
When you compare quotes, compare what is included: plant pre-soak and post-soak, gutters and trim washed with the siding, insurance, and a guarantee. Our checklist on how to choose a pressure washing company lists the questions to ask.
What Every Quote Includes
- Pre-soaking and post-soaking your plants and grass so the cleaning solution never sits on them.
- Soft washing for siding and roofs, with low pressure that protects vinyl, brick, stucco and shingles.
- Cleaning the gutters’ outer faces, trim and doors as part of a house wash, not just the flat siding.
- A final walk-around with you before we leave. That is our 100% satisfaction guarantee.
There are no surprise fees on the day. If something about the job changes, we tell you before we start.
Is DIY Cheaper?
Renting a pressure washer for a weekend costs less up front, but it is the most common way siding gets damaged. High pressure can force water behind vinyl panels, strip paint and leave stripes that look worse than the dirt. It also does not kill the algae, so the green comes back within months.
If you are weighing the two, our guide to pressure washing vs soft washing explains which surfaces can take pressure and which cannot.

Frequently Asked Questions
How much does it cost to power wash a house in Manassas?
Most Manassas homes cost $400 to $800 for a full soft wash house washing. The size of the home and the amount of algae or mildew decide where your home falls in that range.
How much does roof cleaning cost?
Roof soft washing is quoted per job. Roof size, pitch, height and how much moss or black streaking is present all set the price, which is why every roof gets measured before we quote it.
Is it cheaper to bundle services?
Yes. Adding window cleaning to a house wash cuts the window price in half, and one visit means one setup instead of several. Most homeowners pair house washing with gutters or windows.
How long does a house wash take?
Most house washes take 2 to 4 hours, depending on the size of the home and how much buildup there is. Larger homes or jobs with roof cleaning added can take most of a day.
Is power washing worth the cost?
For most homes, yes. Removing algae and mildew protects siding and trim, and a clean exterior is one of the cheapest ways to improve curb appeal before guests, an HOA inspection or a sale.
Do I need to be home for the quote or the cleaning?
No. Most quotes can be done from your address and a few details, and you do not need to be home for the cleaning. We just need access to an outdoor spigot.
