"Ken is very knowledgeable and professional. My backyard was not draining well in the last rain after a garage extension. He graded the soil and built a paving stone walkway. When I couldn't find anyone to put sods on the soil, he took on the job and did a great job. I am very happy with the work."

"Billy came out to my place, gave me a comprehensive estimate for what would actually fix my asphalt driveway, and then was very easy to communicate with about setting up the work. Perhaps most importantly, they actually showed up when they were supposed to! And the work is a massive improvement over our previously cracked, potholed driveway, and they cleaned up everything also. Very happy with our choice, price was very fair as well."

"It had been ten years since any work had been done on this driveway and it was in very bad shape. Joshua and his crew cleaned, patched, and put two thick coats of slurry on the driveway. The work was performed efficiently and very effectively. Very pleased with Joshua's professionalism and the work he performed."

"We had Ocean Seven Builders redo our roof after a small leak turned into a bigger problem. Ron was the one we dealt with, and he just felt easy to talk to from the start. No pressure, no upselling, just explained what made sense. The crew showed up when they said they would and worked pretty steadily through the job. What I noticed most was how clean they kept things?no nails or trash left around. The roof looks great and we?ve had zero issues since."

Driveway Sealcoating FAQs, answered by experts

Most sealing projects take 1-2 days, including drying time before allowing traffic.

It is not recommended to seal brand-new asphalt immediately. You should wait at least three months after installation to allow the asphalt time to cure properly. Applying a seal coat too soon can trap the asphalt's oils and chemicals, preventing it from fully hardening. This can result in a weaker surface that is more susceptible to damage. After the three-month curing period, sealing the asphalt is beneficial as it can extend its lifespan by protecting it from water, UV rays, and other damaging elements.

Depending on the product used, you should avoid using your driveway for 48 to 72 hours after sealing it. In general, water-based driveway sealers cure much faster compared to oil-based and solvent-based sealers. Some driveways are even ready in just four to five hours.

Asphalt is made of aggregate materials (sand, rocks, and gravel) and bitumen, a viscous, petroleum-based, waterproof substance. These materials are mixed together at extremely high temperatures to form asphalt.

New asphalt typically needs 24 to 72 hours to dry before it can handle light foot traffic and careful driving. Although it may appear solid after a few days, the full curing process, where the asphalt reaches its peak strength, takes much longer—generally from 30 days to a year.

During this extended curing time, the surface remains relatively soft and can be damaged by heavy vehicles, sharp objects, or high temperatures. To protect your investment, it's best to avoid parking heavy machinery on the asphalt until it has fully cured.

The exact time required for drying and curing depends on several factors, including the weather, the specific asphalt mix, and its thickness. For the most accurate advice tailored to your situation, consult with your asphalt contractor.
