"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."

"The are hard working professionals. Eddie showed up precisely on time for our estimate appointment and kept an open line of communication throughout. The crew appeared on time and removed and replaced a 60+ year old driveway. The job was completed quickly and with precision. New driveway is gorgeous and I could not be a happier customer. Nor can I recommend this company more highly. A beautiful job at a reasonable price. Thank You to Eddie and his crew!"

"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."

"It worked out well. I haven't gone up there to check the gutters myself. But they had a crew out, they worked. I think they did a good job. They came out the day after I purchased the Big Deal. I got them to give me an estimate to fix the leaks in the roof, but I thought it was too high, so I went with someone else. They did the job efficiently. They had a lot of guys out here. Very good price. I'm assuming it is done properly. We've had a lot of rain and I don't see any problems. I would use them again if they gave me that good deal. It was a good service, but the prices are high, unless you get a discounted offer through Angie's List. The estimate for the roof was very high. The young guys who did the work were really very professional. The job they did was good."

"We?re very satisfied with our roof replacement. Ron coordinated the job really well and made the whole thing easy for us. The crew was quick, professional, and did a great job with both installation and cleanup. The roof looks excellent and we haven?t had any issues since. Overall a great experience and we?d happily use them again!"

Driveway Sealcoating FAQs, 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.

The best ways to increase the lifespan of your driveway are to carry out proper maintenance and get repairs done quickly. First, reseal your driveway every one to three years to protect it from the elements. If you start to notice significant cracks, hire a professional to diagnose the problem before it gets more serious. You can also use sand instead of salt when de-icing your driveway (since salt is corrosive) and clean your driveway annually using a pressure washer to keep it in tip-top shape.

A good rule for all homeowners is to seal every driveway to protect it. Wait at least three months to seal an asphalt driveway and one month to seal a concrete driveway. You know it’s time to reseal your driveway when it shows obvious signs of wear and tear. It may appear as fading or discolored asphalt, small cracks, and oil stains. If you notice that one area of your driveway seems to dry slower than others, it’s time to reseal.

In general, water-based driveway sealers are considered the most eco-friendly option. Products that utilize water, limestone, and some basic binding agents have lower VOC levels and odor levels compared to sealants made with oil or tar. In recent years, soy-based driveway sealers have become available for homeowners who want fully VOC-free driveway sealers.

If your asphalt driveway shows cracks, potholes, or standing water, it’s likely time for a repair. Cracks, big or small, let water seep in, weakening the base and causing further damage. Potholes are a sign of this weakening process in action while standing water suggests your driveway has poor drainage, which can cause even more issues. You may also see warping or buckling—a sign of a compromised base layer—or sinking pavement. Spotting these signs early on can help you save yourself a bigger repair bill in the future.
