Overall happy with the service. The quotation/estimation process was excellent. The work performed was good. I contacted them almost at the end of the season which resulted in some issues due to low temperatures. John has been quite responsive and the issues were resolved.

We needed to lift, relevel, clean and seal extensive backyard interlocking brick around our pool that was installed in 1999. In addition we wished to redesign a backyard stone step coming from our home plus a paver stone walkway running down the side of our home.

We spoke to a few service providers to receive ideas/quotes and selected Master Sealer. John had come to review our project, suggest ideas and promptly provided a quote within a day. We were impressed with John’s approach.

The work was completed timely and in a highly professional manner. The work crew was skilled, took pride in their work and consulted with us as necessary during the project. We are very happy with the end result. John was always available to answer any of our questions.

We have further extensive repair to existing paver stone work in our front yard and driveway to be done in 2026 and we will be calling John once again.

Great job by Master Sealer cleaning, sealing my driveway, front walkway. It’s the third time I’ve used them, they have a better polymeric sand they’re using, hopefully stays hard for longer time. John was very flexible to schedule work at my place.
