Pressure Washing for Dallas Homes — No Guesswork

Professional Pressure Washing Across Dallas-Fort Worth

Dan Keenan Paint Company delivers professional pressure washing throughout Dallas, TX and the wider DFW metroplex. Owner Dan Keenan has led surface preparation work since 1992, and with a 5.0 rating across 81 Google reviews, the company is one of Dallas's most trusted names for both exterior cleaning and paint-prep washing. We clean driveways, concrete, brick and vinyl siding, wood decks, fences, and commercial storefronts — using the correct method and PSI for each surface type.

Why Dallas Exteriors Need Pressure Washing More Often Than Most

Dallas sits in a climate that accelerates exterior surface degradation faster than most American cities. UV index values from May through September regularly hit 10 or above — the same range that causes latex coatings to chalk and oxidize within a single season. Spring pollen storms coat every surface with an acidic film that holds moisture against siding and masonry. Clay soil in neighborhoods like Far North Dallas and Farmers Branch splashes mineral staining onto foundations every time it rains.

Surfaces We Clean with Professional Pressure Washing

Brick and mortar, vinyl and fiber cement siding, painted wood lap siding, concrete driveways and sidewalks, wood decks and patios, fences, retaining walls, and commercial storefronts. Each surface gets the method and pressure setting appropriate for its material — soft washing at 500–800 PSI for siding and painted wood, 1,500–2,000 PSI for brick and stucco, 3,000+ PSI only on concrete hardscape.

Pressure Washing as Paint Prep: The Step That Determines How Long Paint Lasts

Paint adhesion is a surface chemistry problem. Chalk, mildew, oxidation, and clay-soil residue all create a barrier between the paint film and the substrate. Apply primer over any of those contaminants and you're gluing paint to dirt. When Dan Keenan Paint Co. handles both the wash and the exterior paint job, one crew controls the entire prep sequence — clean substrate, confirmed dry time, premium Sherwin-Williams or Benjamin Moore coatings applied on schedule.

Pressure Washing vs. Soft Washing

Pressure washing uses high-PSI water force (1,500–4,000+ PSI) for hard surfaces like concrete, brick, and stone. Soft washing uses low pressure (100–800 PSI) combined with biodegradable detergents and mildewcide to kill biological growth on siding, stucco, and painted wood. The chemistry does the cleaning — not the pressure. We match the method to the material without the homeowner needing to specify.

Our Pressure Washing Process

1. Pre-job inspection of every surface. 2. Site and plant protection — tarps over landscaping, closed windows and vents. 3. EPA-registered biodegradable detergent and mildewcide pre-treatment with appropriate dwell time. 4. Controlled pressure rinse — PSI matched to each surface, top-to-bottom on all vertical surfaces. 5. Final walkthrough and 24–48 hour dry-time confirmation before any scheduled painting work.

Pressure Washing FAQs

How often should I pressure wash my Dallas home?

Most Dallas homes benefit from professional washing once yearly, ideally in late March or April after pollen season. Tree-heavy lots and north-facing walls may need washing twice a year.

Will pressure washing damage my paint or siding?

High-pressure washing at the wrong PSI absolutely can damage paint and vinyl siding. We match pressure settings to each surface — 500–800 PSI soft washing for siding and painted wood, 1,500–2,000 PSI for brick and stucco, 3,000+ PSI only on concrete.

How long should I wait before painting after pressure washing?

Exterior surfaces need 24–48 hours of dry time before paint is applied. Rushing this step is the single most common cause of paint adhesion failure in DFW's humid summers.

Do you treat mold and mildew, or just wash it away?

We treat it. Surface washing without mildewcide only removes visible mold temporarily — spores remain in the substrate and regrow within weeks. Our soft wash solution includes EPA-registered mildewcide that kills biological growth at the root.

Can you pressure wash before painting my home's exterior?

Yes — and we strongly recommend it as part of every exterior paint project. Clients who book the wash and the paint together get a single accountable crew from surface prep through final coat.
