Pressure Washing in Altadena
As a homeowner in Altadena, you're no stranger to the challenges that come with living in a hot dry climate. Summer days can reach scorching temperatures, with highs often exceeding 115°F, while winter nights may drop below freezing at elevation. The extreme temperature fluctuations can take a toll on your home's exterior surfaces, leaving them vulnerable to damage and discoloration.
The median age of homes in Altadena is around 1945, meaning many of our homes are original structures that have been exposed to decades of harsh weather conditions. This means that dirt, mold, mildew, algae, and stains can quickly accumulate on siding, driveways, walkways, decks, patios, fences, and gutters, compromising their integrity and appearance. Without proper maintenance, these issues can lead to costly repairs down the line.
A pressure washing service is essential in Altadena to maintain the health and curb appeal of your home's exterior surfaces. By removing dirt, mold, mildew, algae, and stains, you'll not only restore your home's original color and texture but also prevent damage from further deterioration. With most homeowners on the property themselves, it may seem like a DIY project, but many factors can affect the final cost, such as total square footage to clean, number and type of surfaces, severity of staining or buildup, chemical treatment needed, height and accessibility, and driveway and walkway size.

DIY vs. Call a Pro
Consumer-grade pressure washers (1,500-2,000 PSI) work well for most residential tasks. Use a wide fan nozzle (25-40 degree) for siding, a turbo nozzle for concrete. Keep the nozzle 12-18 inches from surfaces. Never pressure wash windows, and use low pressure on wood to avoid damage.
Call a professional when:
Hire a professional for multi-story homes, soft-wash treatments for delicate surfaces, commercial-grade stain removal, roof cleaning, or when you lack equipment. Pros also carry liability insurance for accidental damage.
