Patrick and Brandon were absolutely amazing to work with. We are so thankful that we hired them to do this project; it could not have been completed without both of them. They oversaw the entire project and were at the house daily to track progress and communicate with all of the contractors and if they were not here they were always reachable. They even stayed on us to make sure that we picked everything out timely and that it would work with the project- this was much needed!!! We could not be happier with how the pool and lanai came out and would recommend them to anyone!
