We had a new vinyl liner installed in our 40 year old pool this week. Louis, Chris and Saul deserved the highest rating possible. Our pool was in a terrible condition. The liner was completely worn out, and the walls were badly rusted. Now it looks like new. These men worked very hard. They had to deal with a water condition under the pool and handled it ingeniously. These men really know what they are doing. I would recommend they to anyone who wants a new swimming pool or needs work on an existing pool
