Do not use this company! They closed and then opened the pool back up in the spring. There were leaks in a PVC fitting. I called them — they sent someone over and sent me a bill. There were still leaks. I called them and they were back again and sent me another bill. I asked why do I need to pay twice and they told me it was a different leak, even though it was leaking from the same place! Anyways, there were still leaks after both visits. I called another company who came over and fixed the leak. They told me that K&M didn’t close the pool properly and the valve froze and cracked.
