Executive Summary: Pressure Washing Houston TX
Pressure washing Houston TX covers soft washing, power washing, and surface cleaning for house exteriors, driveways, patios, roofs, decks, fences, storefronts, and concrete across Greater Houston. It is also the required first step before any exterior painting or deck staining project.
Method is matched to surface: soft wash (low pressure + chemical dwell) for roofs, stucco, and painted wood; high-pressure surface cleaner for concrete driveways and parking lots; turbo nozzle for heavy staining on masonry. Crew of 1–3 technicians. Most residential jobs complete in 2–6 hours.
Houston-specific prep requirements: surfaces near Gulf Coast humidity accumulate mildew and algae faster than most U.S. markets. Plants and electrical items are protected before chemical application. A minimum 24-hour dry time is required before any exterior paint or stain can be applied to a washed surface.

Stop Letting Houston Grime Damage Your Property
Mildew and algae on siding and roofs
Gulf Coast humidity means mildew shows up on north-facing walls and shaded surfaces within a single season. Standard garden hose rinsing spreads spores without killing them. We use a biodegradable mildewcide pre-soak that breaks down organic growth at the root before rinsing.
Concrete staining and surface discoloration
Driveways, patios, and pool decks accumulate oil, rust, algae, and storm debris that a basic rinse won’t shift. A surface cleaner with degreaser pre-treatment lifts deep staining without leaving uneven wand streaks across the concrete.
Dirty surfaces that won’t hold paint or stain
Exterior paint applied over contaminated surfaces fails within months — peeling from the substrate rather than wearing evenly. Every exterior painting and deck and fence staining project we do starts with a thorough surface wash and confirmed dry time.

Our Process: Done Right the First Time
-
1
Surface Assessment & Written EstimateWe identify the surface type, staining level, and correct cleaning method. Plants, outdoor furniture, and any electrical items near the work area are noted for protection. You receive a written estimate before any equipment is set up.
-
2
Pre-Soak, Dwell & CleanDetergent or mildewcide is applied and given dwell time to break down organic growth. PSI is set by surface — soft wash for painted wood and roofs, higher pressure for concrete and masonry. A surface cleaner attachment is used on flat concrete to avoid streaking.
-
3
Rinse, Inspect & Site Clean-UpSurfaces are rinsed thoroughly to remove all chemical and debris. We inspect every area before packing up. No detergent residue left on plants, no muddy runoff pooled at the base of the foundation.
What to Expect: Your Project Timeline
| Stage | When | What Happens |
|---|---|---|
| Estimate & booking | Within 24–48 hours | On-site surface assessment, written quote, method and detergent selection |
| Pre-soak application | Job start | Biodegradable detergent or mildewcide applied; dwell time 5–20 minutes by surface |
| Pressure wash or soft wash | During job | PSI-matched cleaning pass; surface cleaner on flat concrete; soft wash on roof and painted wood |
| Rinse & inspection | End of job | Full rinse-down, walkthrough of all cleaned surfaces, plant and furniture protection removed |
| Dry time (if painting follows) | 24–48 hours after | Surfaces must fully dry before exterior paint or stain is applied |
These are estimates. Heavy staining, large square footage, or multi-surface jobs can extend the schedule. Dry time before painting is non-negotiable.
The Right Time to Schedule Pressure Washing Houston TX
Before any exterior painting or staining project.
Paint and stain applied over dirty, mildewed, or oily surfaces fails fast. Our exterior painting projects always begin with a pressure wash and confirmed dry time — it is part of our standard prep, not an add-on.
Before listing your home.
A clean driveway, fresh exterior, and mildew-free roof read as maintained in listing photos and during open houses. A pressure wash is the lowest-cost improvement per listing dollar spent.
After a Houston storm.
Heavy rain and flooding leave silt, debris, and organic residue on every surface. Storm-season scheduling books quickly — plan your post-storm wash before the season starts rather than after.
Best Months to Book
February through May and September through November are the best windows — mild temperatures, lower humidity, and stable weather. We schedule year-round with adjustments for rain and humidity spikes.
The Henry Contractor Difference
PSI matched to surface
Soft wash for roofs and painted wood. High pressure for concrete and masonry. Wrong PSI strips paint, damages grout, and gouges wood. We select equipment by surface, not convenience.
No hidden fees
Your written estimate covers the full surface scope. Chemical pre-treatment and stain removal are quoted upfront — not added as line items after the crew is already on-site.
Biodegradable detergents
We protect landscaping, seal electrical outlets near work areas, and use plant-safe detergents. Runoff is managed so you are not left with dead hedges or chemical residue near pool equipment.
Transparent Pricing for Pressure Washing Houston TX
| What Drives the Cost | Basic vs. Deep Clean | Hidden Costs to Watch For |
|---|---|---|
| Surface type; concrete holds staining differently than stucco, wood, or tile | Basic: rinse + light detergent. Deep clean: mildewcide or degreaser pre-soak with extended dwell time | Heavy oil or rust staining on concrete may require a second pass — quoted upfront after surface inspection |
| Square footage and access; two-story and roof cleaning adds equipment and safety considerations | Basic: removes loose dirt and pollen. Deep clean: removes embedded algae, black streaks, and organic growth | Soft wash chemical cost varies by mildew severity — heavy infestations use more product per sq ft |
| Surface contamination severity; post-storm residue or years of buildup takes more chemical and time | Basic: one surface pass. Premium: targeted stain treatment on problem areas (rust, oil, graffiti prep) | Vendors who quote per sq ft over the phone without seeing the surface cannot accurately scope chemical or equipment needs |
Residential house washes: estimated $200–$600. Driveways: $100–$300. Commercial surfaces and multi-area jobs: custom bid. Your written quote locks the number before work starts.

Frequently Asked Questions
The short answer is an estimated $200 to $600 for a whole-house exterior wash, $100 to $300 for a driveway, and $150 to $400 for a deck or fence, depending on square footage and staining severity. Commercial surfaces and multi-area jobs are custom bids. All pricing is confirmed after an on-site surface assessment.
The short answer is yes, when the correct method is used. Roofs and painted wood require a soft wash — low-pressure application with a chemical dwell — not a high-pressure wand. High-pressure washing on shingles or painted siding strips surface granules and paint. We select the method by surface, not by convenience.
The short answer is 2 to 6 hours for most residential jobs with a crew of 1 to 3 technicians. A whole-house wash runs 3 to 5 hours. A driveway or patio typically runs 1 to 2 hours. Commercial and multi-surface jobs are scoped individually.
Yes, pressure washing is required before any exterior painting project. Paint applied over dirty, oily, or mildewed surfaces loses adhesion and peels early. Washed surfaces also need a minimum of 24 to 48 hours of dry time before primer or paint can be applied. We include the wash and dry confirmation in every exterior painting scope.
The short answer is a biodegradable mildewcide solution applied as a pre-soak with a dwell time of 5 to 20 minutes before rinsing. Products like Wet and Forget, sodium hypochlorite solutions, and Simple Green Pro HD are selected by surface type. The dwell time is what kills organic growth at the root — rinsing alone does not.
