What we do
Seal coating is the maintenance step that decides whether your asphalt lasts ten years or five. The sun in South Texas is hard on pavement. UV dries the binder that holds the asphalt together, the surface fades from black to gray, and once it is brittle, water and fuel work into it and the raveling and cracking start.
A seal coat is a protective layer we squeegee and spray over sound asphalt. It puts the black back, blocks the UV and water, resists gas and oil drips on a commercial lot, and gives you a clean surface to stripe over. It is a fraction of the cost of repaving, and done on a regular cycle it pushes the repave years down the road.
We seal commercial parking lots and residential driveways. We are honest about when it is worth it: seal coating protects good asphalt, it does not fix a lot that is already failing. If the surface is past saving we will tell you, instead of selling you a coat of sealer over a lot that needs paving.
Our process
First we clean. Sealer only bonds to a clean surface, so we clear the dirt and debris and blow the lot down. We fill or flag the cracks that need attention and mask off the concrete, buildings, and anything that should stay clean.
Then we apply the sealer, cut the edges by hand where the machine cannot reach, and coat the open areas evenly. We keep you off it while it cures, then it is ready to restripe. We give you a clear window for when the lot or driveway can take traffic again before we start.
Who seal coating is for
- Commercial lots on a maintenance cycle
- Property managers protecting a paving investment
- Residential driveways fading from black to gray
- Newer asphalt due for its first protective coat
- Lots about to be restriped that need a fresh base first
- Owners who want to delay a full repave the honest way
What the South Texas sun does to your asphalt
Fresh asphalt is black and flexible because of the binder, the tar that holds the aggregate together. The sun is what kills it. UV dries the binder out, and as it dries the pavement goes from black to gray, loses its flex, and turns brittle. Once it is brittle, the small stones at the surface start to come loose, that is the raveling you see as a rough, sandy texture, and water gets into the cracks and works down into the base.
San Antonio gets a long, strong sun season, so this happens faster here than in a milder climate. A seal coat is the layer that takes the UV hit instead of the pavement, which is exactly why a lot that gets sealed on a cycle outlasts an identical lot that never does.
When sealing is worth it, and when it is not
Seal coating is one of the best-value things you can do for good asphalt and one of the worst things to waste money on for bad asphalt. On a sound lot, it protects the binder, blocks water, resists fuel drips, and pushes the expensive repave years down the road. That math is strongly in your favor.
On a lot that is already failing, with cracking that goes all the way through and a base that is shot, a seal coat is lipstick. It looks fresh for a month and does nothing for the real problem. We will tell you which one you have. If your lot is a good candidate we will seal it and mean it, and if it is past that, we will show you why and talk about paving instead of taking your money for a coat that will not hold.

Seal Coating FAQs
How often should I seal coat my parking lot or driveway?
For most lots and driveways, every two to three years is a reasonable cycle, sooner for a lot that takes heavy traffic or full South Texas sun all day. New asphalt should get its first seal coat once it has fully cured. We will look at your surface and tell you where it is in that cycle.
Will seal coating fix the cracks in my asphalt?
No, and anyone who says it will is selling you something. Seal coating protects a sound surface, it does not repair structural cracking or a failing base. We fill or flag the cracks that seal coating can handle and tell you honestly if the lot has gone past sealing and needs paving.
How long does the lot need to stay closed?
Usually the surface needs several hours to a day to cure before traffic, depending on the heat and humidity. On a commercial lot we can plan the work to keep the closure as short as possible, and we give you the exact window before we start.
Can you seal coat and restripe at the same time?
Yes, and it is the right order. Seal coating gives you a clean, uniform surface, and fresh striping over a fresh seal coat looks sharp and lasts. We can handle both in one visit so the lot only closes once.
Is seal coating really worth it?
On good asphalt, yes. Repaving a lot costs many times what a seal coat costs, and a regular seal-coat cycle protects the binder from UV and keeps water out, which is what pushes the repave years further out. On a lot that is already failing, it is not worth it, and we will say so.
