I had a superlative experience with L.D. Smith on an exterior water main shut-off replacement and internal shut-off valve replacement and repair. This was performed through a UtilityShield claim (now run through HomeServe).
First things first… I tried other companies, and even big names (aka Gluf Plumbing), thought that repairing a water shut off in the water main pit wasn’t “code” or “frowned upon” by Citizens Energy. This is simply not true.
Second, L.D. Smith managed to work with HomeServe, so they must have the patience of a saint. Home warranty companies are nearly universally bad in my experience.
Third – and most importantly – both the folks L.D. Smith sent out were timely, professional, and broke things down to me in a way I could understand.
Last, if you have a commercial repair, I would give these people your money over other folks in town, that’s for sure.
