I wouldnt trust these guys. A guy came out with his clip board and took measurement and photos, I guess he thinks that makes him look professional, who knows. I have been paying $150 a month for 3 years and Pool boys gave me an estimate of "$750 a month" not including filter changes or chemicals. He also said we need to drain our pool because our water was bad. I took a sample to Leslies pool and they said it was fine. Also draining an in ground pool is a myth and a scam. Some pool companies offer mobile filtration systems which remove dissolved solids from your pool water without the need to drain it at all, but only if it tests bad. This companys ethics are way outta line.
