Alex from Swim Clean retrofited our old pool light into a new LED one and fixed some issues with our filter while he was here. Our house and pool was set up 50 years ago in some very odd ways, but Alex was determined to figure it all out and work out a way of getting everything done properly for us. Only through his dogged determination did we get this done. I don't think any other company would have worked as hard to solve our issues. He was respectful, polite and punctual, everything you want in someone coming to work at your house. If we ever have any other problems with our pool Alex and Swim Clean will be our first call!
