Sealcoating is the cheapest way to protect an expensive asphalt surface. Laredo Asphalt Co. seals and maintains driveways and lots across the South Texas border region — extending their life and keeping them looking new.
Protect what you've paid for — call Laredo Asphalt Co. at (956) 476-7635 to schedule sealcoating, or ask us to assess whether your surface is ready for it.
Sun is what breaks asphalt down here. Sealcoating every 2–3 years blocks the UV that turns binder grey and brittle, restores the deep-black finish, and can double the life of your pavement — for a fraction of the cost of repaving.
Schedule Your SealcoatSealcoating is the least expensive line item in pavement ownership and the one with the best return. Here's what it costs.
| Project | Typical range | What drives it |
|---|---|---|
| Sealcoating | $0.20–$0.50/sq ft | Area, surface condition, and single vs double coat |
| Typical two-car driveway | $250–$500 | 640 sq ft (16' × 40') — small enough that the minimum service call usually sets the price rather than the square footage |
| Crack sealing | $0.50–$2 per linear foot | Crack width and total length |
| Commercial lot sealcoat | $0.20–$0.50/sq ft | Large lots price at the lower end of the range |
| Restriping after sealcoat | $5–$12 per stall | Layout complexity; ADA stalls and signage cost more |
| Minimum service call | $250–$500 | Covers mobilising crew and equipment for small jobs |
These are typical Texas market ranges for 2026, published so you can budget before you call. They are not a quote — actual pricing depends on your specific site, and the only number that counts is the written estimate the contractor hands you after measuring.
Larger surfaces price lower per square foot. Sealcoating a driveway and the parking pad in one visit costs less than two separate trips.
Clean, sound pavement seals quickly. Heavy oil staining, weeds in cracks, or a badly oxidised surface needs more preparation before anything is applied.
Cracks must be sealed before sealcoating — sealer alone bridges nothing. This is quoted separately, and it's the part that actually protects your base.
One coat suits a well-maintained residential drive. High-traffic commercial lots and badly oxidised surfaces benefit from two, at additional cost.
Blowing, sweeping, edging, and degreasing are included in a proper job. A quote that skips prep is quoting a coat of sealer that will peel.
Sealcoating covers existing lines, so commercial lots need restriping afterward. Budget for both together.
Two or three years since the last one? Let's take a look — quotes are free and it's the cheapest pavement decision you'll make.
Sealcoating is both oversold and undervalued. It's oversold when contractors present it as a fix for damage it can't address, and undervalued by owners who see it as cosmetic. In South Texas it is closer to essential than optional — here's the accurate version.
Sealcoat is a protective layer applied over the surface. It blocks UV radiation, which is what oxidises asphalt binder and leaves pavement grey, brittle, and prone to ravelling. It resists water penetration through the surface. It shields against oil, fuel, and chemical spills that dissolve binder outright. And it restores the deep black finish that makes a property look maintained.
UV oxidation is the primary way pavement ages in this part of Texas — ahead of traffic, and ahead of water. A surface that has gone grey and started shedding loose stone is not weathered-looking; it is telling you the binder holding the aggregate together has hardened and is letting go. Sealcoat is the only routine maintenance item that addresses that directly, which is why stretching the cycle to save money here costs more than it does in a milder climate.
Sealcoat is roughly the thickness of a coat of paint. It adds no structural strength whatsoever. It will not fix cracks, will not bridge a pothole, will not level a rut, and will not rescue a failed base. Anyone selling sealcoating as a solution to structural problems is selling you a cosmetic cover-up that hides the issue until it worsens.
This is the part most often skipped on cheap bids. Sealer poured over an open crack does not seal it — water continues straight through to the base, which is where the real damage happens. Crack sealing is the step that actually protects the structure; sealcoating protects the surface. They do different jobs and you want both, in that order.
The climate here argues for staying on a two-to-three-year cycle rather than stretching it: intense sun drives oxidation year-round, and summer heat is hard on a surface that has lost its protection. New asphalt should cure six to twelve months before its first coat. Sealcoating needs warm, dry conditions and a clear window to cure, which most of the year provides — the two things to schedule around are the storms that do come and the peak of summer, when a surface can be too hot to take a coat properly.
Sealcoating a typical driveway costs a small fraction of replacing it, and the cycle repeats only every two to three years. Against a resurfacing or replacement bill, the maintenance path is dramatically cheaper over the life of the pavement. That's the entire argument — and it holds up whether you own a single driveway or a portfolio of lots.
Typically $0.20–$0.50/sq ft, but a standard two-car driveway is small enough that most contractors' $250–$500 minimum service call sets the price rather than the square footage. Crack sealing is quoted separately at roughly $0.50–$2 per linear foot. Those are typical Texas ranges for 2026 — a local contractor will give you an exact price for your surface at no cost.
Every 2–3 years for most driveways and lots. High-traffic commercial lots and surfaces in full sun may benefit from the shorter end of that. New asphalt should cure 6–12 months before its first coat — sealing too early can trap oils and leave a soft finish.
Typically 24–48 hours before vehicle traffic, and often at the shorter end here given the temperatures. Foot traffic is usually fine sooner. You'll get exact timing on the day, and sealing shouldn't happen at all if conditions won't allow a proper cure.
No — and this is the most important thing to understand about it. Sealcoat is about the thickness of a coat of paint and adds no structural strength. Cracks must be sealed separately first, before sealcoating. We normally crack-seal and then sealcoat in the same visit, which is both the best result and the better price.
It's both cosmetic and genuinely protective. It blocks the UV oxidation that makes asphalt brittle, resists water penetration, and shields against oil and fuel spills. Given it costs a small fraction of resurfacing and repeats only every few years, it's the highest-return maintenance decision available to a pavement owner.
Yes — arguably more so, because the asset is larger and appearance affects customer perception. It protects a major capital investment, keeps the property looking maintained, and delays costly resurfacing. We can set your property up on a recurring maintenance plan.
Yes. Sealcoating covers existing lines, so any striped lot needs restriping after. We handle both together and budget them as one project, typically restriping the day after the seal has cured.
A proper job includes blowing and sweeping the surface clean, edging back encroaching grass, degreasing oil-stained areas so the sealer will bond, and sealing cracks. Prep is where cheap sealcoating jobs cut corners — sealer applied over a dirty surface peels within months.
Most of the year here — the climate is generous about this. What gets scheduled around is a storm in the curing window and the hottest part of a summer afternoon, when a surface can be too hot to take a coat evenly. We won't seal a damp surface or ahead of a storm just to hold a date; it simply won't bond properly.
You can, but you shouldn't — you'd be paying to make a failing surface look better while the underlying problem continues. If damage is extensive, repairs or resurfacing come first, then sealcoating protects the new work. We'll tell you honestly if sealcoating isn't the right spend right now.
