Gentle soft wash for siding, stucco & brick — dirt, mildew and spiderwebs gone in one visit.
House Washing in Montville, NJ — Soft Wash That Won't Wreck Your Siding
Drive through the Towaco end of Montville and you'll see the same thing on half the houses: gray-green streaking down the north and shaded sides of the siding, worst where the big oaks and maples hang over the yard. That's not dirt you can hose off — it's living algae and mildew feeding on North Jersey's humid summers and the shade our tree canopy throws all day.
Montville's housing stock makes this a soft-wash job, not a pressure job. The vinyl colonials and cedar-shake split-levels off Changebridge Road, the stucco and EIFS on some of the newer builds — none of those want 3,000 PSI blasted at them. Pressure drives water behind vinyl and cracks stucco. We use a low-pressure soft wash: a cleaning solution that kills the algae and mildew at the root, then a gentle rinse. The growth doesn't just get pushed around, it dies and stays gone longer.
Over in Pine Brook and the older sections near the center of town, we see plenty of brick and painted trim that needs the same careful touch. We match the method to what your house is actually made of.

Lucas showed up on time dress in press shirt and paints with a iPad taking notes and pictures. Provided a very reasonable quote and scheduled appointment. The truck 3 team showed up earlier than scheduled and could not have been any nicer. The had a small problem with gear and let me know. Ther office also called and apologized to inform me of the problem. Truck 3 team came back and finished the job. The job they did was excellent. You can see on before pictures I had staining around window where shutters were installed. The after picture you can hardly tell. Super professional, kind and fair price. Wish all vendors were as professional and trustworthy as worthy as Gallo Bros is.”

“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!”

House Washing in Montville — FAQ
My vinyl siding is streaked gray-green on the shady side — will pressure washing fix it?
Those streaks are algae and mildew, not surface dirt, and high pressure won't kill them — it just blows them around and can force water behind the vinyl panels. We soft wash it: a low-pressure cleaning solution kills the growth, then a light rinse. On the shaded, north-facing walls common in Montville's wooded lots, that's the only method that actually keeps it clean into next season.
I have a stucco (EIFS) house near Changebridge — is house washing safe on it?
Yes, but only with soft washing. Stucco and EIFS crack and take on water if you hit them with a pressure wand, and once moisture gets into an EIFS system it's a real repair. We drop the pressure way down and let the solution do the work, so we clear the mildew without opening up the finish.
When's the best time to wash my house in Montville?
Spring and early fall are ideal. Spring gets the winter grime and pollen off before summer humidity kicks the algae back up, and fall cleans it after the growing season. Either way we can usually get you on the schedule the same week you call for a quote.
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.
