Alamo Heights Poolhouse has done an excellent job on my pool. I have some deteriorating plaster which tends to gather algae. When the algae was particularly bad, I asked Andre and his team to eliminate it. He suggested that I sign up for monthly service to eliminate the algae. I was skeptical at first, but it worked! After about a month and a half of monthly service including brushing and vacuuming, the algae was completely gone. Andre under promised and overperformed. I recommend Alamo Heights Poolhouse highly!
