My 16 year old brick paver(Unilock) walkway has been uneven and my patio falling apart. I finally decided to get it fixed and boy did I luck out by finding Sure Seal. I received an estimate in a timely fashion and the owner, Jim, answered all of my questions. Although it was not the lowest estimate I received, it was half of the highest(who told me I needed to replace all of the bricks). Sure Seal’s crew worked for two days, and I don’t know how they did it, but the walkway and patio look absolutely fantastic — almost brand-new looking. The results far exceeded my expectations. I recommend that you contact Sure Seal if your brick walkway is in need of repair.
