Above all, we are watchful of our customers' interests and make their concerns the basis of our business.

"I recently had my driveway paved as well as the secondary driveway treated with gravel and compacting. The contractor was JY Paving- [*** Link removed ***] I was looking for a vendor and had a couple of suggestions from people I trusted. Only one of those entities bothered to come to my house and give me a quote. Then they told me they couldn't do it until next year. So I called a couple of others after doing an internet search and Jim Young was the only one who responded to me. He came to my house where we defined the scope and he gave me a quote. I later expanded the scope and he immediately followed up with the additional, reasonable costs. I thought his quote was more than fair, so I elected to take a chance and trust him. He showed up at my house as promised with all the equipment, paving materials, gravel and personnel required to cover my scope of work. Jim was out there operating the paver and roller and when he wasn't on one of those, he had a shovel or a rake in his hand and was trimming up the sides. Whenever I asked for a tweak here and there, he immediately tended to the issue with a smile on his face, no questions asked. At the end of the day, I had what I felt like was a beautiful primary driveway and secondary driveway. I was very happy to hand him a check reflecting the full amount of the work he and his crew had performed. When you have the owner of a company in the field operating equipment and manning shovels and rakes, you not only get a good product but you get excellent value because he's not paying a foreman to run his operation. I couldn't recommend JY Paving any more highly. He was very pleasant to deal with and offered me a great value."

"I spent a lot of time trying to find someone that could replace my front steps. Getting someone to actually call back was the first challenge. Then, trying to find someone who does everything we wanted: granite steps, faux stone facing and sides, white railings, and the ability to tear up and lower my walkway then redo it to make the first step 7” was an even bigger challenge. We finally found the right guy/company and we are very happy with the results. Walter Santos of W. Santos Construction did it all for us. He started within days of us accepting his proposal. He was kind, communicated the next steps with us well, and the quality was fantastic. I was outside tonight taking photos and a family was taking a walk stopped me to ask who did the steps because “they make the house.” I took some dry and wet pics after the dust was washed off and I’m very happy with the results. He even came out to finish on Memorial Day."

Driveway Sealcoating questions, answered by experts

Sealing your driveway gives it the longest possible lifespan. You’ll reduce your driveway’s risk of cracking, breaking down from exposure to UV light, discoloring, and staining from road chemicals.

In general, crack fillers last for about two years on average. That timeline can be shorter if you have extremely harsh winters or longer if you live in a mild climate. Luckily, this product is pretty affordable at the hardware store (about $10 to $30) and easy to DIY, so redoing it every few years shouldn’t be too much of a hassle.

You should always power wash your driveway before applying a sealant. At any given time, your driveway could be covered with algae and moss, tire residue, oil and rust stains, and any combination of leaves, twigs, and dirt. If you skip power washing, you’ll be trapping the dirt and grime beneath the sealant and lowering its chance of cementing itself to your driveway. While you can expect the cost to pressure wash your driveway to average between $100 and $350, the few hundred dollars beats an unattractive driveway or paying extra to reapply your driveway sealer.

On average, asphalt dries within 24 to 72 hours, meaning it’s solid enough for light traffic—walking and careful driving. Full curing—when asphalt reaches peak strength—can take anywhere from three months to a year. During that time, heavy loads and sharp objects can leave marks. Weather, asphalt mix, and thickness all affect how quickly it dries and cures. If you want your asphalt to last, treat it gently until it’s fully cured. For the best results, check with a professional asphalt contractor for their advice.

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.
