The four measurements that set your Mountain House price
Wall square footage, story count, flatwork area and stain type are the only four inputs that move an exterior cleaning price in 95391.
Wall area is taken as measured surface, not house square footage — a 2,200-square-foot floor plan in Questa may carry only 1,800 square feet of washable wall once garage doors, windows and covered entries come out.
Story count is a labor multiplier, not a material one. Two-story elevations carry a 15 percent adjustment on the wash rate and an extra $3 per window on glass, because reaching the second course safely on a Mountain House lot means ladders and longer wands.
Flatwork is straightforward area, and stain type is the wildcard. Ordinary tire film is included in the $0.30 per square foot concrete rate. Oil that has soaked into the paste carries a $25 to $75 pre-treatment depending on how deep it has gone.

Worked examples on real Mountain House floor plans
A typical Mountain House two-story with 2,000 square feet of stucco and a 600-square-foot driveway comes to roughly $1,008 for both services quoted separately.
That breaks down as $828 for the walls — 2,000 square feet at $0.36 plus the 15 percent two-story adjustment — and $180 for 600 square feet of driveway at $0.30. Bought as the Curb Appeal bundle instead, the pairing is $447 when the measured footage lands at the smaller end, which is why the bundle exists.
A single-story Wicklund home with 1,200 square feet of Hardie board is a cheaper job: $264 at the $0.22 fiber cement rate, which sits under the $297 standalone minimum and so is sold with flatwork or windows alongside it.
Add a 1,400-square-foot concrete tile roof at $0.55 and the roof alone is $770. Paired with a 160-foot gutter clean at $1.60 per foot, the Gutter Combo bundle covers both for $840 rather than $1,026 bought apart.

Why the Mountain House minimum is $297
The $297 standalone minimum covers the run out I-205 to 95391 plus setup, insurance and documentation, none of which get cheaper on a small job.
A 400-square-foot driveway prices at $120 on the rate sheet. That figure is real, but it is an add-on rate — it describes what the driveway adds to a visit, not what a truck rolling to Mountain House for that one item costs.
This is worth knowing before you compare quotes. A company advertising $99 driveways in 95391 is either pricing a much smaller area, using a wand instead of a surface cleaner, or planning to find the rest of the money once they are on your property.
The honest version is the bundle. Every sub-minimum rate on this page is achievable — just as part of a visit that also does something else. Two services on one trip is almost always cheaper than the same two services on two trips.

What Mountain House quotes should include in writing
A complete 95391 quote names the measured area, the rate applied, the pressure method per surface, and what happens if a stain does not fully lift.
Method matters as much as price. A quote that says 'pressure wash house' without specifying low-pressure soft washing on stucco is quoting a job that can damage the wall, and the cheaper number often reflects exactly that shortcut.
Ask what the pre-treatment allowance is. On Mountain House driveways the oil pre-treatment range of $25 to $75 should be named up front rather than appearing as a surprise line once the surface cleaner reveals the extent of a stain.
Finally, ask what documentation you get. Exterior Prime photographs each surface before and after at every 95391 address, which is what lets you settle a question about the finished condition weeks later.
