Our complete pool/spa underwater pool repair service specializes in reinforcement steel removal (rusted rebar), crack repair, resurfacing, delamination, calcium nodule removal and underwater drain retrofit to comply with the VGB Pool & Spa Safety Act. We repair Pebble, Quarzite and gemstone pools as well as plaster pools. San Diego County chose our us to demonstrate underwater drain retrofit for a drowning prevention campaign video, played on television news. Advantages of repairing pools underwater: -Little downtime. -Prevents risk of damage to the plaster that may occur when a pool is drained. The removal of water and the tremendous weight associated with it alters the pool's equilibrium and can precipitate damage to the pool's plaster. -Saves the cost of start-up chemicals and water. -Prevents pool chemicals from flowing into our ecosystems.
