I recently purchased a whole house Enviro water filter system from Strongbuilt. Gilbert R installed it and did a superb job. All the copper fittings are very professionally done. I’d recommend anyone to use Strongbuilt as I interfaced with John M about this system first. John was very up front and honest to talk to. Earlier this year I purchased a new water heater from Strongbuilt and John M did a very impressive job installing it. I am very glad to have found such a reliable plumbing and air company for service.
