"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 had a big kitchen remodel with layout changes, so we were a bit nervous at first. Ron made the process a lot easier than expected. He coordinated everything and made sure each step was done properly before moving on. The workmanship is solid, and the finishes look high-end. We?re really happy we chose Ocean Seven Builders!"

Driveway Sealcoating questions, answered by experts

Instead of a set number of types, asphalt comes in variations designed for different needs. Some are categorized by temperature—hot mix, warm mix, and cold mix. Others are sorted by composition, like dense-graded, gap-graded (such as Stone Matrix Asphalt), porous, and mastic asphalt. There are also modified versions with added compounds like polymers, rubber, or emulsions. Instead of focusing on a number, it may be more useful to understand how contractors customize asphalt for durability, climate, and traffic conditions.

Fading color, visible cracks, or water pooling signal the need for sealing to prevent further damage.

Costs depend on lot size, sealant quality, labor, and any additional surface preparation.

Yes, most professional repair services include the application of sealants for weatherproofing or waterproofing. This process helps protect the repaired area from moisture, weather damage, and future wear, which can improve durability and energy efficiency. It is always best to confirm with your contractor or service provider if sealing is included in their repair process.

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