Pressure Washing FAQ

House washing: $250–$600 depending on home size. Driveway cleaning: $150–$350. Roof soft wash: $350–$700. Deck/fence cleaning: $200–$500. Gutter cleaning: $150–$300. Most Magnolia homes complete a full exterior cleaning package for $600–$1,200. Free estimates provided.

Soft washing uses low pressure (similar to a garden hose) with biodegradable cleaning chemistry to kill biological growth — algae, mold, mildew — at the root. Pressure washing uses high pressure to physically remove dirt and staining. Soft washing is the appropriate method for siding, roofs, and painted surfaces where high pressure could cause damage. Pressure washing is appropriate for concrete, brick hardscaping, and surfaces that can withstand high pressure.

Magnolia driveways under tree canopy develop green algae because shade keeps concrete damp, organic debris from pine needles and leaves provides nutrients, and Montgomery County's humidity supports continuous biological growth. Chemical pre-treatment before pressure washing is necessary — pressure alone without chemistry pushes algae into concrete pores rather than removing it, causing faster regrowth.

High-pressure washing is NOT safe for asphalt shingles — it removes the ceramic granule coating, accelerates shingle deterioration, and voids most manufacturer warranties. The ARMA (Asphalt Roofing Manufacturers Association) recommends soft washing — low-pressure sodium hypochlorite application — as the correct method for asphalt shingle roof cleaning. We exclusively use soft wash for all asphalt shingle roofs.

On heavily shaded Magnolia homes, algae may begin re-establishing within 12–18 months on north-facing walls. South-facing and more exposed surfaces typically stay clean for 2–3 years. Most Magnolia homeowners schedule annual house washing, with some scheduling twice yearly for heavily wooded lots.

Yes. Composite decks require different chemistry and lower pressure than wood decks. Most composite manufacturers (Trex, TimberTech, Fiberon) specifically warn against high-pressure washing and certain chemical types. We use composite-manufacturer-approved cleaning methods and chemistry for all composite deck cleaning.

Yes. We use hot water with commercial degreaser for oil and grease stains. Results depend on stain age and depth — fresh stains respond significantly better than old embedded stains. We set realistic expectations during the estimate for old or large oil deposits that may not fully remove without surface treatment beyond cleaning.

Twice per year minimum for most Magnolia homes — once in late spring after oak pollen and sweetgum ball drop, and once in late fall after pine needle accumulation peaks. Homes under heavy pine canopy may benefit from 3–4 cleanings per year. Clogged gutters in Magnolia's high-rainfall environment cause roof edge rot, siding water staining, and foundation erosion.

Black streaks on asphalt shingles are caused by Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in asphalt shingles. It spreads from spores and thrives in Magnolia's humid, pine-needle environment. It's not just aesthetic — untreated algae consumes the shingle material and shortens roof life. Soft wash treatment kills and removes it.

Yes. We provide commercial pressure washing for building facades, concrete flatwork, parking lots, storefront areas, and commercial properties along SH-249 and in both Magnolia and Tomball commercial areas. Commercial quotes provided based on scope.

In Magnolia's humidity, wood should dry for at least 48–72 hours after cleaning before stain or sealer application. Check moisture content with a moisture meter — wood should be below 15% for optimal stain penetration. We advise on timing based on current weather conditions during the service visit.

We pre-rinse all plants and landscaping near the work area before chemical application and post-rinse after. Our cleaning chemistry is biodegradable and applied at concentrations appropriate for exterior surfaces — not ground application. We protect plants, shrubs, and garden areas as part of our standard process.

Yes. The Woodlands is part of our service territory. The Woodlands' forest-preserve master plan creates the same organic growth challenges as Magnolia — heavy canopy, algae-prone driveways, and pine needle-loaded roofs. We serve all Woodlands villages.

We use biodegradable surfactants and sodium hypochlorite (bleach) at appropriate concentrations for each application. Sodium hypochlorite is the ARMA-recommended active ingredient for roof soft washing and is effective against all common biological growth types. All chemistry is applied at concentrations safe for the specific surface being cleaned and is thoroughly rinsed after treatment.

No. Most gutter guard types don't effectively block Magnolia's thin pine needles, which penetrate many guard systems. Moss also grows on top of metal gutter guards. Guards reduce cleaning frequency for some debris types but don't eliminate the need for periodic cleaning in Magnolia's high-debris environment.

Yes. We have the equipment to safely wash two-story and taller homes in Magnolia. High-reach soft wash wands and appropriate ladder equipment allow us to access all exterior surfaces safely.

Close all windows and doors before we arrive. Remove loose items from decks, patios, and areas adjacent to the work zone. Ensure water access is available. For house washing, park vehicles away from the work area or in the garage. For gutter cleaning, clear access around the home's perimeter.

Not necessarily. Many customers provide gate access codes and let us complete the work while they're away. We document all service with before/after photos and notify you when the job is complete. For first-time service, we prefer a brief walkthrough conversation in person or by phone to discuss any specific concerns.

Yes. We carry general liability insurance for all residential and commercial pressure washing work in Montgomery County and Harris County. Our team is trained in proper pressure and chemical application to prevent surface damage. Certificate of insurance available upon request.

We primarily serve Magnolia (77354, 77355), Tomball (77375, 77377), and The Woodlands (77380, 77381, 77382). We also serve other Montgomery County and north Harris County communities adjacent to our core territory. Contact us to confirm coverage for your address.
