Pressure Washing in San Marcos, TX 78666
Pressure washing in San Marcos cleans driveways, patios and walkways, and we soft wash siding and roofs. San Marcos averages about 32 inches of rain a year with 18 days at 100 degrees, going by San Antonio International, so mildew grows on damp walls while summer heat bakes dust onto concrete and roofs.

What we clean on San Marcos homes, and how
Most San Marcos properties mix several materials. Each one gets its own method. The median home in San Marcos was built in 2001, and about 35% of homes are single-family detached houses, per the 2019 to 2023 American Community Survey (via Point2Homes).
Painted block and stucco
San Antonio International, the nearest long-term station, averages 32.38 inches of rain on 81.3 days a year, enough damp days for algae and mildew to settle on shaded painted siding and brick in San Marcos.
Soft wash with a low-pressure rinse. No blasting, so the paint stays on and water stays out of hairline cracks.
Concrete driveways and walks
San Antonio International logs 17.7 days a year at 100 degrees or more, and that heat bakes dust and pollen onto San Marcos concrete driveways and walks until they look gray and stained.
Rotary surface cleaner for an even finish, with no wand stripes.
Pavers
May averages 4.40 inches of rain at San Antonio International and June 3.28, so spring storms in San Marcos wash sand from paver and flagstone joints and leave soil on patios.
Lower pressure, then a check on the joint sand before we leave.
Pool decks and porches
July highs average 94.9 degrees at San Antonio International and 122.4 days a year reach 90 or more, so San Marcos wood decks and fences dry out and gray, with dust settling in the grain.
Surface cleaner on the deck and a gentle wash on screens and trim.
Tile and shingle roofs
San Marcos's median home was built in 2001, so many shingle roofs are about 25 years old, and summer highs near 94 degrees bake dust onto them until shaded slopes streak dark.
Low-pressure cleaning solution and a gentle rinse. No pressure on the roof surface.
Rust and sprinkler stains
San Marcos's drought stages follow the Edwards Aquifer, and when the city entered Stage 3 on Oct. 27, 2024, hose-end sprinklers dropped to one day every other week, so uneven watering and overspray can leave spots.
We test the stain first, because rust needs a different treatment than algae.

These are typical price ranges for this work, so you have a number in mind before you call. We confirm your exact price by phone, for free, before we start.
Size and stories
More square footage and more height mean more time.

Light algae is quick. Years of mildew or a streaked roof take longer.
Material
Pavers and delicate finishes take more care than plain concrete.
Access
Tight side yards, screened porches and gates change the setup.
Ranges are typical for homes, not a quote, and can run higher or lower. Describe your property and we will give you a firm number.
Call for your exact priceWhen to wash a house in San Marcos
There is no wrong month, but the season changes what we see and how long a clean lasts.
Hurricane season
Tropical storms can bring heavy rain and debris onto roofs, walls and driveways, mostly near the coast (highest risk August to September). After a storm, call us to see what needs washing.
Spring and fall rains
Rain peaks in spring and fall near the Gulf Coast and humidity is higher in the east, so algae and mildew can build on shaded roofs and walls.
Cedar pollen season
Juniper (cedar) pollen peaks around mid-January in the Hill Country and east Texas and can leave a film on cars, siding and patios.

Pressure washing FAQ for San Marcos
A question that is not here? Call us and ask.
Scheduling and coverage
Do you serve San Marcos, TX 78666 and nearby areas?
Yes. We work across San Marcos, including Downtown San Marcos, Dunbar, Sessom Creek, Hughson Heights, Victory Gardens and Spring Lake Hills. Call with your address and we will confirm coverage.
How soon can you come out?
It depends on the schedule and the weather. Give us the address and the surface, and we will tell you the soonest opening instead of guessing.
What happens if it rains or a storm is coming?
We reschedule. Wet weather does not hurt a roof or wall wash, but a storm warning is a reason to move the date, and we will call you.
Methods and safety
Will pressure washing damage my stucco or roof?
Not when the method fits the surface. Stucco, painted block and roofs get a low-pressure soft wash. We keep pressure for concrete and similar hard surfaces and test a small spot first.
Can you clean pavers without losing the sand?
Yes. We use lower pressure on pavers and check the joint sand before we leave. If a joint needs more sand, we point it out.
How long does a clean last in San Marcos?
It depends on shade, sprinklers and how wet the season is. Shaded spots and areas near sprinklers green up first. After the job we tell you what to expect for your surfaces.
Pricing, insurance and water rules
How much does pressure washing cost in San Marcos?
Typical ranges are on this page: roughly $100 – $500 for a driveway, $250 – $400 for a patio or pool deck, and $150 – $1,400 for a house exterior depending on height. Your exact price comes from a free phone quote.
Why does the same job cost more at one house?
Size, height, how much growth is on the surface and how hard it is to reach all change the time and solution needed. We explain what drives your number.
Are you insured?
Yes. Ask for proof of insurance when we quote the job.
Are there water restrictions in San Marcos?
I could not open San Marcos's drought page. A May 19, 2026 summary named no stage, only Edwards Aquifer J-17 readings. In 2023, Stages 3 and 4 banned washing impervious surfaces. Confirm today's stage with the City of San Marcos. Rules can change, so we check the current rules before we book.
