The Highest-ROI Thing You Can Do for Concrete
Sealer is the cheapest protection concrete has. A quality sealer soaks into the surface and blocks the three things that destroy concrete in Northern Virginia: water that freezes, road salt that attacks the surface, and oil that stains it permanently. Sealed concrete lasts years longer, looks better the whole time, and cleans up easier. Unsealed concrete takes the full beating of every winter.
What We Seal
Driveways, patios, walkways, pool decks, stamped and decorative concrete — any exterior concrete that faces weather. New concrete should be sealed within its first year (after curing, typically 28 days). Existing concrete should be resealed every 3 to 5 years, or every 2 to 3 for stamped and colored work where the sealer also protects the color.
The Right Sealer for the Job
- Penetrating sealers. Soak in and protect without changing the look — the choice for plain broom-finish driveways. Invisible protection.
- Film-forming sealers. Build a protective film on top that deepens color and adds a sheen — the choice for stamped, colored, and exposed aggregate, where the look matters.
- Traction additive. Mixed into film-forming sealers for stamped concrete and pool decks — grip without changing the appearance.
How to Tell It Is Time
Pour water on the concrete. If it beads up, the sealer is still working. If it soaks in and darkens the slab, the protection is gone. Fall is the ideal season — seal before the first freeze and the concrete goes into winter armored.
What It Costs
Sealing is our most affordable service — most driveways run a few hundred dollars, a small fraction of what a premature replacement costs. Get a quote and protect the driveway you already paid for.
Penetrating vs. Film-Forming: Which Your Concrete Needs
Not all sealers do the same job, and the wrong choice is money wasted. Penetrating sealers soak into the concrete and protect from within — invisible, natural-looking, and the right call for plain broom-finish driveways and walkways. They do not change the appearance at all. Film-forming sealers build a protective layer on top — they deepen color, add a subtle sheen, and are the right call for stamped, colored, and exposed aggregate concrete, where the sealer is part of the look. What matters most is matching the sealer to the surface and applying it correctly: the right coverage rate, the right weather window (above 50 degrees, no rain for 24 hours), and a surface that is actually clean first. Sealer over dirt is sealer wasted.
Our Process: Clean, Repair, Seal
- Inspection. We check the concrete's condition and the old sealer (if any) — some sealers need stripping before resealing, and we test rather than guess.
- Deep cleaning. The surface gets pressure-washed and degreased. Oil spots get treated; the sealer needs clean concrete to bond.
- Minor repairs. Small cracks get filled before sealing — sealing over open cracks just seals the water in.
- Application. The matched sealer goes on at the manufacturer's coverage rate — penetrating for plain concrete, film-forming for decorative, with traction grit where slip matters. Edges and details get hand work.
- Cure. Foot traffic in hours, vehicles in 24 to 48 hours depending on the product and weather. We give you the exact timing.
What Sealing Costs in Fairfax County
Sealing is our most affordable service and the highest return: most driveways run $400 to $900 depending on size and sealer type, patios and walkways less, large or decorative surfaces more. Compare that to the cost of a premature replacement and the math is obvious. Estimates are free — tell us the approximate size and we will give you a written price.
The Reseal Schedule: What Actually Works
The question we hear most: how often? The honest answer depends on the sealer and the surface. Penetrating sealers on plain driveways: every 4 to 5 years in our climate. Film-forming sealers on stamped and decorative concrete: every 2 to 3 years — the film wears faster and the color depends on it. Pool decks and high-traffic commercial walks: every 2 years. And the water test never lies: pour water on the concrete, and if it soaks in instead of beading, the protection is gone regardless of the calendar. One more timing note — seal in spring or fall, when temperatures sit above 50 degrees and rain is not imminent. Sealer applied onto a hot summer slab flashes too fast; sealer applied before a cold snap never cures right.
