Question 1

Is pressure washing safe for my driveway?

Accepted Answer

Done correctly, yes. Concrete tolerates it well; the damage stories come from wrong pressure or wrong technique on the wrong surface. That's what "professional-grade" is for.

Question 2

Why does my concrete get slick every winter?

Accepted Answer

Algae growth and moss cause concrete to become slick. It thrives in our wet season. Washing removes it; annual maintenance keeps it from re-establishing thickly.

Question 3

Do you wash siding or decks too?

Accepted Answer

Ask during your assessment. Some surfaces we handle; some need gentler methods than pressure washing, and we'll tell you which is which.

Question 4

Can pressure washing remove moss from concrete?

Accepted Answer

Yes, moss and algae on hard surfaces respond well to washing. Roof moss is different and needs gentler, non-pressure treatment; see our Roof Moss Prevention & Removal page for that.
