DIY vs. Professional Pressure Washing
Why risking thousands in siding damage isn't worth saving a few dollars on a weekend rental.
The DIY Risks
Retail pressure washers (like standard Ryobi or Craftsman box store units) operate by blasting incredibly concentrated water streams—often upwards of 3,500 to 4,000 PSI. Homeowners attempting to clean organic growth from their siding with these units frequently inflict irreversible catastrophic damage.
- Forcing water behind vinyl siding panels, causing trapped mold and internal drywall rot.
- Stripping the UV-protective coating and oxidation layer off aluminum and vinyl siding, leaving permanent zebra stripes.
- Fracturing fragile window seals and etching glass with high-pressure nozzles.
