If you live in San Antonio, you already know that the Texas heat, humidity, and seasonal storms are not kind to the exterior of your home. Dirt, mold, mildew, algae, and pollen build up fast — and if left untreated, they can cause lasting damage to your siding, driveway, roof, and fencing. So how often should you pressure wash your home? The answer depends on a few key factors, but here’s what Texas Pure Clean recommends for San Antonio homeowners.

The Short Answer: Once a Year at Minimum

For most San Antonio homes, an annual pressure wash is the bare minimum. However, certain surfaces and situations call for more frequent cleaning. A professional pressure washing service will remove built-up grime, prevent long-term staining, and keep your home looking fresh and well-maintained year-round.

Recommended Cleaning Schedules by Surface

Driveways and Walkways – Every 6 to 12 Months

Your driveway takes a beating from vehicle traffic, oil drips, and weather exposure. In San Antonio’s climate, algae and mold can form quickly — especially in shaded areas. We recommend cleaning driveways and walkways at least once a year, and every six months if you notice heavy buildup or staining.

House Siding – Once a Year

Vinyl, brick, and stucco siding all attract dirt, mildew, and pollen. A yearly soft wash or pressure wash will protect the surface, improve curb appeal, and prevent mold from working its way into cracks and crevices.

Roof – Every 1 to 2 Years

Roof algae (the black streaking you often see on shingles) is extremely common in the San Antonio area due to our warm, humid climate. Left untreated, algae and moss can actually shorten the life of your shingles. Roof cleaning every one to two years using a soft wash method protects your investment and maintains your home’s value.

Fences and Decks – Every 1 to 2 Years

Wood fences and decks are especially vulnerable to moisture, mold, and UV damage. Annual cleaning followed by sealing or staining will dramatically extend their lifespan. Composite decking can typically go two years between cleanings.

Gutters – Twice a Year

Clogged gutters can cause water damage to your fascia boards, foundation, and landscaping. We recommend gutter cleaning in the spring and fall to keep them flowing freely.

Signs You Should Schedule a Pressure Wash Now

• Black or green staining on your roof, siding, or driveway
• Visible mold or mildew around windows and doors
• A driveway or walkway that looks gray instead of its original color
• Your home looks noticeably darker or dirtier than your neighbors’
• You’re getting ready to sell, paint, or seal any exterior surfaces

Why Professional Pressure Washing Beats DIY in San Antonio

While renting a pressure washer from a local hardware store might seem like a good idea, improper technique and pressure settings can damage siding, strip paint, and even void roofing warranties. Texas Pure Clean uses commercial-grade equipment and proven techniques — including soft washing for delicate surfaces — to get the job done right without causing harm.
