Always be leery about using the guy offering the great deal out of his truck, because often times it is not. In this business you definitely get what you pay for, and cheaper isn't always better.

 

What kind of material do you use?

We use Overkote with 2% latex for maximum adhesion. Our crack fill preference is a low-tack product by Crafco which is used on freeways, main roads, and driveways.

 

When should I seal a newly paved driveway?

A new driveway needs time to cure for at least 3-6 months pending on how oily the mix is. If you seal the asphalt before that the sealer can lock in the oils keeping the asphalt soft and decreasing its life expectancy.

 

Does my driveway need a second coat?

The only time you should get a second coat is if has not been sealed for a very long time (completely dried out and has a whitish gray look) or a newly paved driveway that has cured for at least a couple months

 

How often should I seal / crack fill my driveway?

We come out and evaluate the condition of your asphalt as each driveway is different. Sealcoat needs to be worn down before applying a new coat so that it can have a proper bond. We typically get our customers on a maintenance program between 2-4 years pending on the condition of the asphalt.

Crack filling is recommended every year because it is inexpensive and helps prevent the water from widening the cracks and damaging the subgrade.
 

What causes the sealer to flake?

There are several factors that go into why flaking can occur:

- Not washing the surface prior to sealing is a big reason which is why we pressure wash before sealing.

- Cold spots that ice up and water dripping off your roof or surrounding trees.

- Gas spills and oil leaks.

- Over sealing your driveway

- Leaving snow on your asphalt over the winter.

- Standing water from sprinkler systems overspraying.

​

How long do I need to stay off my newly sealed driveway?

Upon completion the asphalt will need at least 24 hours of sunlight. Meaning if you sealed it on a Monday you may drive on it Tuesday night. Longer is always better if you are able to. This same rule applies to sprinklers that when coming on hit the driveway. Also avoid turning tires in one spot especially on hot days as it will cause scuffing.

 

As a homeowner what do I need to do?

- Move all objects off the driveway.

- Cut back edges of the driveway.

- Secure any animals.

- Turn off sprinkler systems.

- Spray weed killer in cracks if weeds or grass are growing.

- Clean any dirt piles.
