Outstanding Work
5 Stars – Outstanding Work.
I recently had L. Graziose Plumbing Heating & Cooling completely update the plumbing in my bathroom, and I couldn’t be happier with the results! They installed a new shower body and upgraded all the valves for better pressure and reliability—no more drips.
From start to finish, the team was professional, on time, and incredibly thorough. They provided upfront pricing and worked efficiently without unnecessary disruptions.
I highly recommend L. Graziose. Special thanks to Nicole, Scott, Hector, and Kevin! We’ll definitely call them for future needs.

They came out on Thanksgiving Day and saved what would have been a terrible weekend.
Temporarily fixed the shower and came back to finish the job when I had the new faucets.
Jordan was awesome and explained everything.

Love the services Graziose provides. They make scheduling easy. Nicole keeps the lines of communication working so you know when help will arrive.
