Marc is professional and did great work to extend the life of a worn driveway. Additionally his friendly and honest attitude made him great to work with.

Marc was prompt to accept the job and I felt the cost was within my budget. Really cleaned up all the big cracks and areas that needed filling. End-results are ok.

Asphalt Sealing
GM sprayed on the asphalt sealer. They oversprayed onto my concrete garage apron. For 6+ weeks they have promised to return and clean the overspray. They still have not cleaned up their mess. I will never contract with them again.
Response from GM Seal Coating and Concrete

"We have tried to contact you several times you did not answer our phone call Jeff we are sorry for the inconvenience, but it was not a big splash. It was small little spots that I could take care of. It usually happens when the machine acts up it's not potentially. I left you a voicemail and text messages you will not answer our call. We need your permission to come to your house when you are home so we could take care of it but anyway give us a call and we will come out and take care of it. Not a problem."

Marc and Gary Hill cleaned and sealed my pavers (front walk, partial driveway, and patio). Also, cleaned and sealed my driveway (asphalt). They did an excellent job. I would highly recommend them. They were prompt and explained things very clearly.

Mark and his son showed up on time. Very customer service oriented. Excellent workmanship at a very fair price. Asphalt drive looks like new. They also filled bigger cracks with hot rubber and smaller cracks with fine ground asphalt before sealing. Highly recommend. Also they were able to squeeze us in last minute!

I initially gave them a good report because I was happy with the results. But then within days areas that were sealed started, crumbling and weeds coming through. I contacted him and he said that they would come back and fix it. Well, that didn?t happen he gave me excuses and said he?d come back first thing in the spring. I?ve contacted him several times with no response. I?m very disappointed a professional should not make promises and not follow through with them now I am left with a driveway that has issues again. Not happy!!

In contrast to oher poviders, GM was extremely prompt in responding to my request for an estimate. Furthermore, they were able to begin the work promptly and completed it within the projected timeframe. Communication throughout the project was excellent; the cost was reasonable; and the results met or even exceeded my expectations. I would use their services again and would recommend them to others.

Mark responded to me right away after inquiry and he was the only person I had to work with. They were out the next day. Price was a little higher than other quotes but those only came with a 90 day warranty and this one came with 2 years. Responsive and very service oriented
