Paver Sealing & Polymeric Sand in Chatham, NJ
Re-sand and seal your pavers to lock out weeds, stains and wash-out for years.
Paver Sealing & Polymeric Sand in Chatham, NJ
Most of the paver work we get called for in Chatham falls into two buckets. In the Borough, closer to the Main Street corridor and the older brick colonials, you've got tighter lots — front walks and small patios where the pavers sit under mature trees. Those shaded joints hold moisture, and by late summer you'll see green in the sand and black algae creeping across the surface. That's the same Gloeocapsa staining we clean off north-facing roofs, just down at ground level.
Out in the Township sections and the newer cul-de-sac subdivisions, the jobs are bigger driveways and rear patios that catch full sun but take a beating from freeze-thaw. Water gets into loose joints, freezes, and starts lifting and shifting pavers by spring.
Either way, the fix is the same order of work: clean it right, re-sand the joints with polymeric sand so weeds and ants stop coming up, then seal. Skip the cleaning or use the wrong sand and the seal just locks in the problem. We do it in the right order because after a North Jersey winter, that's what actually holds.

“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.”

Paver Sealing & Polymeric Sand in Chatham — FAQ
My back patio pavers are under trees and the sand between them keeps turning green — will sealing stop that?
Sealing helps, but the green is algae feeding on damp, shaded joints — common on Chatham's tree-canopy patios. We clean it out first, re-sand with polymeric sand, then seal. The sealer slows regrowth and makes the surface easier to rinse off, but shaded pavers may still need a wash every couple years.
The joint sand on my driveway washes out every time we get a heavy summer storm. Is polymeric sand worth it?
Yes. Regular sand runs off; polymeric sand hardens after it's wetted in, so it stays put through downpours and resists weeds and ants. On Chatham driveways that pitch toward the street, it's the difference between re-sanding every year and leaving it alone for several.
How does winter road salt affect sealed pavers near the driveway apron and front steps?
Salt and freeze-thaw are what chew up unsealed pavers around here — water soaks the joints, freezes, and lifts them. A proper seal reduces water absorption so there's less to freeze, and locked-in polymeric joints hold the pavers tight. We recommend sealing before winter, not after the damage shows.
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.
