We hired Gappsi to clean and seal the pavers on our pool deck and around the rest of the house, to re-level the bricks, and to install a new rail by our stairs. They did a great job. The pool deck and walkways look like new. They came when they were supposed to, were professional and did the job. We are very happy with them.

We worked with Gappsi to marble dust our gunite pool and seal the pavers around it. They were very responsive and completed the project quickly. Very happy with the pavers - they look great! When minor issues came up, they were quick to correct them. Gappsi went above and beyond!

Can’t say enough great things about Guiseppe and Gappsi. Have been a customer for over 13 years. Did tile repair for my pool which they renovated 13 years ago. It’s great to have a company that returns your call, is honest, fair and professional. Highly recommend.
