Soft Washing in Mendham, NJ
The safe, low-pressure method for delicate surfaces that high pressure would damage.
Soft Washing in Mendham, NJ — Cedar, Stucco, and Shaded Roofs Done Right
Mendham's housing splits pretty cleanly, and so does the work. In and around the Borough's historic district you've got older clapboard and cedar-shake homes, painted trim, and a lot of shade from mature oaks and maples. That tree cover is exactly why the north and east faces turn green — mildew and algae love the damp, slow-drying siding that rarely sees direct sun. You can't blast that off cedar or old paint with a pressure washer without splintering wood and driving water behind the boards. That's a soft wash job: low pressure, the right cleaning solution, done by hand.
Out in the newer sections toward Brookside and the cul-de-sac subdivisions, it's more vinyl siding and stucco or EIFS colonials. Vinyl holds black algae streaks (Gloeocapsa) across whole walls after our humid North Jersey summers, and stucco stains if you hit it too hard. Both respond to a soft wash, not high PSI.
North-facing asphalt roofs here streak black for the same reason — shade and humidity. We treat the algae at the surface so it rinses and dies back, instead of grinding granules off your shingles.

“We hired Gallo Bros Power Washing to power wash, re-sand and seal our 20 year old paver patio and front walk. They also performed a few repairs and reset a few areas that needed attention. We had never had this done professionally before. From the beginning estimating phase to the final coat of sealer, we were very happy with the services provided, the price and the final result, which they also warrantee for 1 year. I highly recommend Gallo Bros. Power Washing and will use them for other services in the future.”

“Before and after photos attached. Gallo Bros Power Washing is a must. Our pavers were full of weeds which took me hours to pull out only to have to do again a week later when they grew back. With two short days, our pavers looked brand new. After the men power washed our pavers, my husband and I could barely believe they did not totally replace them haha When they arrived day 2 to fill in and sand the pavers, again we were speechless. Our yard looks completely new. We are so appreciative of the quick and professional work they did as well as the friendliness and quick responses we received. Highly recommend this service!”

Soft Washing in Mendham — FAQ
My cedar shake siding has green patches on the shaded side — can you clean it without damaging the wood?
Yes. Cedar and older painted clapboard can't take pressure without splintering or forcing water behind the boards. We soft wash with low pressure and a cleaning solution that kills the mildew and algae at the root, so it doesn't come right back after the next humid stretch. The shaded north and east faces in the historic district are almost always the worst, and that's normal here given the tree canopy.
There are black streaks all down my asphalt roof — do I need a new roof or can soft washing fix it?
Usually it's not roof failure, it's Gloeocapsa algae — the black streaking you see on shaded roofs all over Mendham. Pressure washing a shingle roof strips the granules and voids warranties. We soft wash it: apply a treatment that kills the algae so it loosens and weathers off, no high pressure touching the shingles. It buys you years before anyone needs to talk replacement.
Will the cleaning solution hurt my plantings or the stucco on my house?
No. We pre-wet and rinse landscaping, and on stucco or EIFS we use low pressure and the correct mix so we don't drive water into the wall system or leave streaks. Stucco shows damage fast if it's hit hard, which is exactly why soft washing is the right method for the newer colonials in town.
What is soft washing?
Soft washing cleans with low pressure plus a cleaning solution instead of blasting the surface. It kills algae, mold and mildew at the root and is safe for roofs, siding, stucco and painted surfaces.
Soft washing vs pressure washing — what's the difference?
Pressure washing uses high-pressure water and is for hard surfaces like concrete. Soft washing uses low pressure and a cleaner, and is for delicate surfaces like roofs and siding that high pressure would damage.
Is soft washing safe for plants?
Yes. We wet down and rinse surrounding landscaping before and after, and use solutions that break down safely. Your plants are protected.
How long does soft washing last?
Because it kills the algae and mold instead of just rinsing it off, soft washing stays clean far longer than pressure washing alone — often 2–3x as long.
