Pressure Washing in Boston

A beautiful rose bush stands in front of a classic Jamaica Plain triple decker with a freshly cleaned porch.

New England’s four‑season cycle leaves its mark on every exterior: green algae blooms after humid summers, salty road spray crusts siding through winter, and pollen blankets decks each spring.

Ryan Painting’s professional pressure‑washing service delivers a spotless, paint‑ready surface without carving gouges into cedar or forcing water behind vinyl panels. Whether you’re prepping for a full repaint or just want your property looking fresh for summer, our wash packages bring instant, affordable curb appeal.

We’re proud of what we do

A deck beneath mature oaks was stained black with tannins and mildew. Using a wood‑safe peroxide cleaner and 800 psi rinse, we lifted grime without feathering fibers. An oxalic brightener restored rich color, ready for our stain crew.

FAQs

Will pressure washing damage my cedar shingles or windows?

We adjust PSI and nozzles; cedar and glass are cleaned with low‑pressure (soft‑wash) techniques to avoid damage.

Do I need to be home during the wash?

No—just close windows and move fragile patio décor; we’ll handle the rest.

How long must surfaces dry before painting or staining?

Wood needs 24–48 hours of dry weather; siding can be painted the next day in good conditions.

How much water do you use?

An average home wash consumes about 250 gallons—roughly a quarter of what a garden hose would use in the same time.
