Complete Pressure Washing & Surface Sealing in San Jose
Why just clean your outdoor surfaces when you can protect them for years? Pressure washing alone leaves porous concrete and stone vulnerable to new oil drips and water damage. Our combined Clean & Seal treatment blasts away stubborn dirt, then seals the surface to stop future stains dead in their tracks.
Why Pressure Washing + Sealing Works Best
Unsealed concrete and stone act like hard sponges that continually absorb stains and moisture. Here is why the dual treatment is essential:
Stops Vehicle Oil Absorption
Driveway oil leaks soak deep into bare concrete within minutes. Washing removes surface grime, and sealing creates a barrier that keeps motor oil from penetrating the pores.
Prevents Mold & Algae Return
Unsealed washed surfaces trap moisture, allowing green algae to grow back in months. Applying sealer starves spores of water, keeping concrete clean up to 3x longer.
Protects Against Surface Erosion
Bay Area rain seeps into concrete microscopic gaps. Weather changes cause expansion that flakes away surface finish. Sealer locks out water to stop surface crumbling.

Our Clean & Seal Process
Deep Rotary Washing
We scrub concrete using industrial surface cleaners to remove ground-in dirt, tire marks, and mold.
Degreasing & Spot Treatment
We treat oil and battery acid spots with specialized degreasers to lift deep-set stains from concrete pores.
Complete Drying Phase
We ensure the surface is thoroughly dry so penetrating sealers can soak deep into the material matrix.
Penetrating Sealer Application
We apply high-grade silane-siloxane sealer that creates an invisible, hydrophobic shield against water and oil.
Frequently Asked Questions
Why should I seal my concrete immediately after pressure washing?
Pressure washing opens up concrete pores by removing packed dirt. Sealing immediately after drying locks out oil, water, and dirt while the pores are clean, preserving that fresh look for 3 to 5 years.
Will sealing make my driveway or patio slippery?
No! We use deep-penetrating silane-siloxane sealants that absorb directly into the concrete rather than forming a slick topical plastic coat, keeping original surface traction completely safe.
How long after sealing can I park my car on the driveway?
You can walk on sealed concrete after 4 to 6 hours. We recommend waiting 24 to 48 hours before driving or parking vehicles on the newly sealed driveway.
