Paver Sealing & Polymeric Sand in Flemington, NJ
Re-sand and seal your pavers to lock out weeds, stains and wash-out for years.
Paver Sealing & Polymeric Sand in Flemington, NJ
If you own a paver patio, walkway, or driveway in Flemington, you already know what our Hunterdon County weather does to it. The freeze-thaw cycles that roll through from November into March push and heave the joints, wash out the sand, and leave the door open for weeds and ants. Add the shade many yards get from mature oaks and maples off roads like Barley Sheaf and out toward Sergeantsville, and you get that green-black organic film that makes clean pavers look tired.
We're Gallo Bros, a family-owned exterior cleaning outfit working throughout North Jersey and down into Hunterdon. Paver sealing isn't a bolt-on for us. We clean the surface properly first, replace the old joint material with polymeric sand so it locks up and resists washout, then apply a sealer suited to what you actually have—clay brick pavers common on the older borough streets, or the concrete pavers you see on newer builds off Route 31 and Route 202.
We don't oversell. Some driveways need it, some patios can wait a season. We'll tell you straight what we see, give you an honest price, and do the prep right so the seal actually holds up through a Flemington winter.

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!”

Paver Sealing & Polymeric Sand in Flemington — FAQ
How often should I reseal pavers in Flemington?
For most Hunterdon County homes, every 2 to 4 years depending on sun exposure, traffic, and how much runoff and shade the area gets. A south-facing driveway off Route 31 wears differently than a shaded backyard patio. We'll check the current sealer and tell you honestly whether it's time.
What is polymeric sand and do I need it?
It's a joint sand mixed with a binder that hardens when activated with water. It resists the weed growth, ant tunneling, and washout that regular sand can't handle—especially important here with our heavy rain and freeze-thaw movement. We recommend it on nearly every paver seal we do.
Can you seal pavers in the winter?
No. Sealing and polymeric sand both need dry conditions and temperatures typically above 50°F to cure right. In Flemington that means we schedule work spring through fall. We'll get you on the calendar early rather than rush a bad application in cold weather.
Will sealing make my pavers look wet or shiny?
That's your call. We offer finishes from natural/matte to a wet-look enhancement. We'll show you options so you get the look you want, whether it's a subtle protection or a richer color on your patio.
Do you clean the pavers before sealing?
Always. Sealing over dirt, organic growth, or old failing sealer traps the problem underneath. We soft wash or surface-clean the pavers, let them dry, re-sand the joints, then seal. Prep is the part that makes it last.
Do you do paver sealing near me?
We cover all of North Jersey from Randolph — Morris, Bergen, Passaic, Somerset, Sussex, Hunterdon, Essex, Warren and Union Counties — and paver restoration is the work we do most. Quotes are free and on site, usually within the same week.
What is paver restoration, versus just sealing?
Sealing on its own is a coat on top. A restoration is the whole job: strip the surface and the joints, re-sand with polymeric sand so the joints lock up again, then seal. Sealing over failed joints looks fine for a season and then the weeds come back through.
How much does paver sealing cost in NJ?
Most patios and driveways land between $1.50 and $4 per square foot depending on condition, joint size and which sealer you choose. 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.
