Cuccias Asphalt is a family owned business we offer free estimates are fuly insured and the owner Thomas is on all jobs from start to finish.

"NOT GOOD!!!!! They came to me looking for work and i provided work for them. They started off acting nice and trying to be polite.Long story short they convinced my to pay before the work was complete, When i question them they said we'll leave everything here, even offered to give me the keys to the paver. I should of took them. Because they came back the next morning loading up and never brought it back. Instead sent two guys in a pickup with shovels, racks and what look to be a 12" hand held vibrator to finish a spot appx 20' x 12'. There's footprints and many other poor workmanship eussies they said could and would be fixed .When ask multiply times when are you coming to make repairs. They either said today after we get done with another job or first thing in the morning. Which they never did (liars) Needless to say it looks like **** and after days of calling THEY NEVER CAME BACK"

Driveway Sealcoating questions, answered by experts

If the goal is to reduce your lifetime asphalt driveway repair cost, driveway sealers with oil bases tend to last longer because their composition allows them to penetrate deeper into your driveway's asphalt. This provides deeper, longer-lasting protection compared to water-based products that tend to simply sit on the surface of the asphalt. Knowing that you won't have to redo your driveway as often could leave more room in your budget to cover something like the cost of a heated driveway.

Sealing coat asphalt after 6-12 months and then every 2-3 years is recommended.

Many services include sealing as part of the repair process. Confirm with your contractor.

You shouldn’t directly paint over an oil stain on your asphalt driveway. While painting over might visually conceal the stain, the oil will continue to damage the driveway. Once you’ve noticed the oil stain, it’s important to thoroughly remove it within the next few months since oil stains only take six months before they begin to damage the structure of your asphalt driveway.

Asphalt driveway sealer lasts approximately one to three years. Although the industry standard is to add fresh sealant every two years, this ultimately depends on where you live. Your driveway is subjected to elements like harsh sunlight, freezing temperatures, precipitation, and extra wear and tear that comes from foot traffic and heavy cars. If you start noticing small cracks or uneven drying on your driveway, it’s a sign that your previous seal coat has run its course and your driveway needs a new one.
