Paver Sealing & Polymeric Sand in Bernardsville, NJ
Re-sand and seal your pavers to lock out weeds, stains and wash-out for years.
Paver Sealing & Polymeric Sand in Bernardsville, NJ
If you own a home around Bernardsville, you already know the terrain doesn't do you any favors. A lot of properties up off Mine Brook Road, Claremont, and the hills toward the Somerset Hills sit on slopes with mature tree cover, so paver patios and walkways see a steady mix of shade, moisture, and leaf litter. That combination breeds moss, weeds in the joints, and washed-out sand faster than folks expect.
We're Gallo Bros, a family-owned exterior cleaning crew working across North Jersey. For paver sealing we keep it simple: we clean the surface first, replace failed or missing joint material with polymeric sand, let everything dry properly, then apply the sealer. Skipping the cleaning and sand steps is why a lot of driveways end up hazy or with weeds pushing right back through by summer.
Here in Somerset County the real enemy is the freeze-thaw cycle. Water seeps into open joints in fall, freezes, and shifts pavers over the winter. Locking those joints with polymeric sand and sealing before the cold sets in is the honest fix. We'll walk your patio or driveway, tell you what it actually needs, and give you a straight quote.

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!”

Paver Sealing & Polymeric Sand in Bernardsville — FAQ
When is the best time to seal pavers in Bernardsville?
Late spring through early fall works best. You want dry pavers, warm temperatures, and no rain in the forecast so the polymeric sand can cure and the sealer can cure properly before Somerset County's freeze-thaw season sets in.
Do you replace the sand in the joints too?
Yes. We remove failed joint material and install polymeric sand, which hardens to lock the pavers together and resist weeds and washout. Sealing without addressing the joints is a short-term fix, so we treat it as one job.
How often should pavers be resealed?
Most Bernardsville patios and driveways do well on a roughly 2-3 year cycle, though shaded, tree-covered areas that stay damp may need it sooner. We'll give you an honest read based on your specific surface and exposure.
Will sealing get rid of the green film and weeds?
We clean and treat organic growth before sealing, and the combination of fresh polymeric sand plus sealer greatly reduces how fast moss and weeds return. On heavily shaded lots, occasional upkeep is still normal.
Do you serve just Bernardsville?
No, we're based in North Jersey and cover Bernardsville along with surrounding Somerset Hills towns. Reach out and we'll confirm we cover your street.
How much does paver sealing cost in NJ?
Most patios and driveways run about $1.50–$3.50 per square foot depending on condition and sealer. We clean, re-sand and seal — and quote it all up front, free.
What is polymeric sand and why does it matter?
Polymeric sand goes in the joints between pavers and hardens when wet. It locks the pavers in place and blocks weeds, ants and wash-out far better than regular sand.
How long does paver sealing last?
Usually 3–5 years before a re-seal, depending on traffic and sun. Sealing also brings back the color and makes the surface much easier to keep clean.
Do you clean the pavers first?
Always. We deep-clean, remove old failing sand, re-sand the joints with polymeric sand, then seal. Sealing dirty pavers just locks the dirt in — we never skip the prep.
