House Washing in Denville, NJ
Gentle soft wash for siding, stucco & brick — dirt, mildew and spiderwebs gone in one visit.
House Washing in Denville, NJ
Denville homes take a beating from the shade. Between the mature oaks and maples around Indian Lake, Cedar Lake, and the older neighborhoods off Diamond Spring Road, a lot of houses here sit in damp, tree-covered lots where the north side never really dries out. That's exactly where green algae, gray mildew, and those black streaks start creeping across siding — and why scrubbing once with a hose barely lasts a season.
We're Gallo Bros, a family-owned exterior cleaning crew working right here in Morris County. For house washing we use a soft wash approach: low-pressure application with cleaning solutions that actually kill the organic growth at the root instead of just blasting the surface. That matters on the mix of homes you see around Denville — vinyl-sided colonials, older cedar shakes near the lakes, and stucco. High pressure can carve into wood, force water behind siding, and void manufacturer warranties. Soft washing doesn't.
We'll walk your property, tell you honestly what needs cleaning and what doesn't, and give you a straight price before we start. No upsells, no surprises. Serving Denville, Rockaway, Boonton, and the surrounding towns.
- Local crew that knows Denville homes
- Soft-wash & low-pressure methods that protect your surfaces

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!”

“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.”

“Gallo Bros did an amazing job power-washing my home and roof. They assured me that if I had any concerns they would avail themselves to resolve them. After the cleaning a few leaves blocked the gutter after a heavy rain. They responded quickly and courteously, removing the blockage touched up ,y skylights as well. Before leaving they made sure I was satisfied. Oscar and his team came a few weeks later and sanded and sealed my paver walkway. They were polite and professional, explaining what they were doing, how long it would take, and instructions to ensure the best possible result. What I loved most was the professionalism in their communication. There were several days that we were rescheduled due to heavy rains and storms. The first thing they assured us of was their intent to make sure the job was done correctly. They would not come out to do the work, only to have it washed away. They stayed in contact every step of the way and I felt more than comfortable that the job would get completed the right way. If they couldn’t reach h me by phone they always left a voicemail or sent a text. I just happened to call them first in my search for roof cleaning, but I will never have to look further for these services again. I was really so impressed. Thank you Gallo Bros!”

House Washing in Denville — FAQ
How much does house washing cost in Denville?
Price depends on the size of your home, siding type, and how much growth has built up. A typical single-family colonial or ranch usually lands in a predictable range, and we give you a firm quote after seeing the property — never a random phone number.
Will soft washing damage my siding or cedar shakes?
No. We use low pressure paired with the right cleaning solution for your surface, whether it's vinyl, stucco, or the cedar shakes common near Indian Lake and Cedar Lake. It's the safest method and won't force water behind panels the way high-pressure blasting can.
How often should Denville homes be washed?
Because so many Denville lots are shaded and hold moisture, most homes benefit from a wash every 1–2 years. Heavily tree-covered or north-facing sides often need it sooner since algae returns faster where sunlight is scarce.
When is the best time of year to wash my house?
Spring through fall works best in North Jersey. We like to clear off the winter's mildew in spring and knock back growth before it sets in for the cold months. We work around New Jersey's weather to catch dry windows.
Do you service the whole Denville area?
Yes — we cover all of Denville including the Indian Lake, Cedar Lake, and downtown areas, plus nearby Rockaway, Boonton, Mountain Lakes, and the rest of Morris County.
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.
