Asphalt seal coating in San Antonio, TX

Commercial and residential asphalt sealcoating backed by a one-year warranty, with surface prep and crack filling handled by Pro-Line Paving crews rather than subcontractors.

Seal coating protects asphalt against UV exposure, surface heat, and heavy summer downpours that break down pavement binder faster in South Texas than almost anywhere else.

Asphalt fails from the top down. San Antonio sun oxidizes the binder holding the aggregate together, the surface turns gray and brittle, and once water reaches the base through hairline cracks the damage moves into the structure, where asphalt repair costs several times what a seal coat does. Pro-Line Paving has sealed and maintained pavement across San Antonio and Central Texas since 1995, on retail and industrial parking lots, HOA drives and residential driveways, with every part of the job handled by our own crews.

How Sealcoating Prevents Asphalt Cracking and Premature Wear

Sealcoating puts a wear layer between your pavement and everything that degrades it. San Antonio asphalt takes UV exposure nearly year-round, and that sunlight oxidizes the liquid binder holding the aggregate together until the surface goes gray, loses flexibility and starts to ravel. Sealed pavement resists that oxidation, sheds water instead of letting it work into hairline cracks, and holds up against the oil and fuel drips that soften unsealed asphalt in parking stalls. Applied on schedule, a seal coat slows the aging curve enough to push a full asphalt milling and overlay years further out.

Restoring the Finish on Faded Asphalt Surfaces

A fresh seal coat pulls faded, gray pavement back to a deep uniform black, and on a commercial lot that finish is doing more than looking good. Fresh sealant gives pavement markings the contrast they need, so stall lines, fire lanes and ADA stencils read clearly instead of washing into worn asphalt. It also covers the patchwork left behind by past repairs, which is usually the first thing a tenant, customer or property inspector notices about a property. Pro-Line handles sealing and striping with the same crews, so the lot gets sealed, cured and re-marked in one scheduled sequence rather than across two vendors.

OUR 3-STEP SEALCOATING PROCESS IN SAN ANTONIO

Most seal coats that fail do it because of what happened before the sealer went down, not the sealer itself. Pro-Line crews handle prep, filling and application in-house on the same visit, so nothing gets sealed over that should have been repaired first, and every job carries a one-year warranty.

01

SURFACE PREP & CRACK FILLING

A Solid Start

Sealer bonds to clean, sound pavement. We blow and sweep the surface, cut back vegetation at joints and edges, degrease oil and fuel stains, then rout and fill working cracks. Anything failed through to the base gets asphalt repair before sealing, not after.

02

SEALANT APPLICATION

 Smooth & Even Coverage

We use commercial-grade coal tar and asphalt emulsion sealers rated for Texas heat, UV load and traffic volume. Crews cut in perimeters and islands by hand, then cover open areas by squeegee, brush or spray depending on lot size. Even coverage is what stops drive lanes wearing thin first.

03

CURING & FINAL INSPECTION

Ensuring Quality

Fresh sealer cures in roughly 24 to 48 hours depending on heat, humidity and shade, and we barricade and stage the reopening so a commercial lot can come back in sections. Once cured we walk the surface for thin spots and missed edges, recoating high-traffic areas as needed.

OUR 3-STEP SEALCOATING PROCESS IN SAN ANTONIO

Most seal coats that fail do it because of what happened before the sealer went down, not the sealer itself. Pro-Line handles prep, application and finishing in-house on the same visit rather than passing the work to a subcontractor, and every job carries a one-year warranty.

01

SURFACE PREP & CRACK FILLING

A Solid Start

Preparation is what makes a seal coat last. We thoroughly clean the asphalt surface to remove dirt, debris, oil stains and vegetation, so the sealant bonds properly with the pavement. Anything that has failed through to the base gets asphalt repair before sealing rather than being coated over.

02

SEALANT APPLICATION

 Smooth & Even Coverage

We use commercial-grade sealants formulated to withstand Texas heat, rain and traffic. Our crews apply the seal coat by squeegee, brush or spray system depending on the size and needs of the surface, working evenly and with precision to create a uniform protective layer across the full pavement area.

03

CURING & FINAL INSPECTION

Ensuring Quality

After application the seal coat is given ample time to cure before the surface carries traffic again. Once cured we inspect the full area for a smooth, consistent finish with no missed spots or defects, and reapply in high-traffic or high-wear areas where added protection is needed.

Why Pro-Line Paving Is the Local Choice for Sealcoating in San Antonio, TX

Pro-Line Paving has worked on commercial asphalt across South and Central Texas since 1995. Sealcoating sits inside a turnkey asphalt paving operation that handles every part of parking lot development in-house, which is what keeps quality control and deadlines under our own roof rather than a subcontractor's.

COMMERCIAL-GRADE SEALANTS BUILT FOR TEXAS

We use high-performance coal tar and asphalt emulsion based sealants formulated to resist weather, chemicals and wear. These are commercial-grade products chosen to hold up under Texas heat, rain, and heavy traffic, not the thinned material that fades within a season.

IN-HOUSE CREWS AND A ONE-YEAR WARRANTY

Pro-Line does not subcontract. Our crews are trained in surface prep, application technique and finishing, and the same team handles the job start to finish, whether it is a residential driveway or a large commercial parking lot. Every job is backed by a one-year warranty.

CUSTOMIZED PAVEMENT MAINTENANCE PLANS

Not sure how often your pavement needs sealing? We assess the surface and build a maintenance plan around your property's usage, age, and exposure, so the work happens on the right schedule rather than too early or too late. For commercial lots that often means pairing seal work with pavement marking in the same visit.

SCHEDULING BUILT AROUND YOUR OPERATIONS

Sealcoating means closing part of your property while it cures, so we schedule to minimize downtime. Busy lots can be phased in sections so parking stays available throughout, and we leave the property cleaner and better protected than we found it.

PAVING SAN ANTONIO SINCE 1995

Thirty years of asphalt work across San Antonio and Central Texas, with pavement maintained for CPS, HEB, Microsoft and USAA. Recognitions include the Premier Business Award from CityOf.com San Antonio, 2010 Contractor of the Year from J House General Contracting, and active membership in the San Antonio Chapter of the American Subcontractors Association.

Where We Apply Sealcoating Across San Antonio

Sealcoating is not one job. Pro-Line seals commercial parking lots for retail centers, office parks and HOA properties, where busy sites can be phased in sections so parking stays available and the work pairs with pavement marking once the surface has cured. We seal roadways and access drives as part of the same road development work that covers asphalt milling and overlay, so a surface too far gone to seal gets the treatment it actually needs. And we seal residential driveways with the same crews, the same prep and the same one-year warranty that backs every job, whether it is a single driveway or a multi-acre lot.

Seal Coating FAQs

  • How often should I seal coat my asphalt?

    Every two to three years, depending on traffic and weather exposure. A busy retail lot with concentrated drive lanes and full sun needs it closer to the two year mark, while a low-traffic residential driveway can often stretch further. We assess pavement age, usage and exposure and build a maintenance schedule around that specific property.

  • How long after seal coating can I drive on the surface?

    Cure time depends on heat, humidity and how much shade the surface gets. We schedule the work to minimize downtime and can phase larger lots in sections so parking stays available while each area cures.

  • Does seal coating fix cracks and potholes?

    No. Sealcoating is a surface treatment that protects asphalt from moisture, UV and chemical damage, not a structural repair. Cracks are filled and damaged areas receive asphalt repair before the sealer goes down, since coating over a failing surface only hides the problem for a season.

  • Do you offer crack sealing separately from sealcoating?

    Yes. Repairs and crack filling are part of our in-house service list, so they can be handled on their own or as prep before a seal coat. Filling cracks stops water from reaching the base, which is where a small surface issue turns into a structural one.

  • How much does sealcoating cost in San Antonio?

    Pricing depends on square footage, the condition of the surface and how much prep and crack filling it needs before sealing. A neglected lot with heavy staining and open cracks takes more work than one on a maintenance schedule. We provide free estimates after assessing the pavement.

  • Do you seal residential driveways or only commercial lots?

    Both. Our crews handle everything from a single residential driveway to a large commercial parking lot, with the same prep, application and finishing standards on each. Every job is backed by a one-year warranty regardless of size.

  • When is my pavement too far gone to seal coat?

    Sealcoating protects asphalt that is still structurally sound. Once the surface has extensive alligator cracking, potholes or base failure, asphalt milling and overlay is the right treatment instead. We tell you which one your pavement needs rather than selling the cheaper option and having it fail.

  • What areas do you serve besides San Antonio?

    We work across South and Central Texas, including New Braunfels, Boerne, Seguin, Schertz, Bulverde, San Marcos, Kerrville, Castroville, Fredericksburg and surrounding communities.
