Sealcoating and Crack Filling in Rockford, IL
Rockford Driveway Paving seals and crack-fills asphalt driveways, and also does driveway replacement, resurfacing, patching, new paving, gravel conversion, extensions, and parking lot work. We sealcoat residential drives across Rockford, Loves Park, Machesney Park, Belvidere, Roscoe, and Winnebago and Boone counties, Illinois.
We clean the surface, cut and fill the working cracks with hot rubberized crack filler, let it set, then pull asphalt emulsion sealer across the driveway with a squeegee so it works into the texture instead of skimming over it. Here is the honest part most sealing outfits leave off their page: this is surface protection and nothing else. Sealer keeps water and sun off sound asphalt. It carries no load, it bridges no crack you can put a finger in, and it adds no strength to anything underneath.
What Sealer Actually Buys You
Asphalt ages from the top down. Sun oxidizes the binder holding the stone together, the surface turns gray, and it starts shedding grit. Water then gets into the surface texture and freezes there. A sealed driveway resists both, sheds water faster, and cleans up better after oil drips. That is a real benefit on a driveway that is still structurally fine.
When Sealing Is the Wrong Purchase
Sealer over an alligatored driveway is paint on a break. It looks new for one season, and the same web reappears through it because the ground below is still moving. If your drive is cracked in a connected pattern, rutted, or holding water in low spots, we will tell you to keep the money and talk about the base instead. Selling a coat over that would be easy and it would waste your spring.
Timing and Cure
Sealer needs warm, dry weather with no rain in the forecast for a day either side. Stay off the surface for the cure window we give you, and keep cars off longer than foot traffic. Sealing runs through the warm months here and stops when the nights get cold, because the film will not cure properly below a reasonable temperature.
Booking
We schedule sealing around the paving calendar, which means the busiest stretch is mid-summer through early fall. Crack filling can often happen sooner. Call (815) 555-0155 and describe what the driveway looks like. If the answer is that yours does not need us this year, we will say that too.
How often should you sealcoat a driveway?
Every two to three years fits this climate. Annual sealing is the mistake we see most often. Each coat adds thickness, and once the buildup passes what the surface can flex with, it cracks and lifts away in sheets that look far worse than plain asphalt. If your driveway still looks black and sheds water, it does not need a coat this year.
When can a new driveway be sealed?
Wait roughly six months to a year. Fresh hot mix still holds the lighter oils that make it flexible, and it needs time to release them. Sealing too early traps them in and can leave the surface soft and prone to scuffing. There is no rush from a protection standpoint either. New asphalt is at its most water-tight the day it is rolled.
Should cracks be filled before or after sealing?
Before, always. Sealer is thin. It flows into a crack and settles, so a sealed-over crack shows again within weeks and the water path underneath was never closed. Cracks get cleaned out and filled with hot rubberized filler first, the filler sets, then sealer goes over the whole surface. Doing it in the other order means paying for both and getting one.
Is squeegee or spray application better?
Squeegee work pushes sealer down into the surface texture and leaves a heavier, more even film, which is why we use it on driveways. Spray covers ground faster and suits big open lots, and it is often followed by a squeegee pass anyway. The bigger variable is not the tool. It is whether the surface was clean and dry when the sealer went on.
