House Washing in Chatham, NJ — Safe Soft Washing for Your Siding
Chatham splits into two very different jobs for us. In the Borough, closer to Main Street and the older streets near the train, you get tighter lots, mature street trees, and a lot of brick colonials mixed with painted clapboard and stucco. Out in the Township, the subdivisions run to vinyl-sided splits, bi-levels, and newer colonials on wider lots with more sun — but still plenty of shade where the oaks and maples grew in.
That tree canopy is the whole story here. North- and east-facing walls that sit under branches all day stay damp, and that's where the green mildew and dark algae streaking shows up first. Pressure washing forces water behind siding and strips paint off older clapboard, so we don't do that on a home. We soft wash — low pressure, a cleaning solution that kills the growth at the root, then a rinse. It's the right call on vinyl, cedar shake, and stucco alike.
North Jersey summers are humid enough to feed that black algae (Gloeocapsa) fast, and spring pollen coats everything under the canopy. If your siding looks dingier on the shaded side, that's the mildew — and it comes back faster once it's established.

“Gallo Bros powerwashing team headed up by Joe, did a great job on our exposed, lakefront home. They went above and beyond to remove dirt and mildew from our house siding, soffits and multiple bluestone patios and walkways, as well as our dock and wood furniture. They also took great care to avoid or work around multiple bird nests which had recently hatched babies pre fledge. I will definitely call them in the future!”
Cathy Marshall
“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.”

House Washing in Chatham — FAQ
My split-level in Chatham Township has vinyl siding with green streaks on the north side — will pressure washing damage it?
It can. High pressure drives water up under vinyl laps and into the wall cavity, and it won't actually kill the mildew — it just knocks off the surface layer so it regrows in weeks. We soft wash instead: low pressure plus a solution that kills the algae and mildew at the root, so the north face stays clean far longer.
We have an older cedar shake home near the historic district. Is soft washing safe on cedar?
Yes, and it's really the only safe method for cedar. Pressure will gouge soft cedar and blow out the grain. We use low pressure and a gentle cleaning mix to lift the mildew and gray weathering without tearing up the shakes. On stucco and painted clapboard around those older streets we take the same careful approach.
When's the best time to have my house washed in Chatham?
Late spring through early fall is ideal. Spring clears off the winter grime and the pollen load that builds up under all the tree cover here. If you're on a heavily shaded lot where mildew keeps returning, a wash every year or two keeps it in check. We can usually schedule same-week.
How much does house washing cost in NJ?
Most North Jersey homes run about $300–$550 for a full exterior soft wash, depending on size and stories. Quotes are free and firm.
Will it damage my siding?
No. We soft wash siding, stucco and brick with low pressure and a cleaning solution, so it lifts dirt, mildew and spiderwebs without forcing water behind the panels.
How often should I have my house washed?
Once every 1–2 years for most homes. Shaded, wooded or north-facing walls grow algae faster and may need it yearly.
Do I need to be home?
No. As long as we have access to the exterior and outdoor water, you don't need to be home. We'll confirm everything's spotless before we leave.
