“Our basement had old, damaged pipes that created a horrible flood and soaked and ruined our whole carpet. The basement was almost like a swamp. This plumber showed up on fairly short notice and ended this catastrophe very quickly. Completely solved our problem and did so quickly. Thank you so much.“

“Very personable and professional service by Mike. Arrived during the stated time period. Wore ‘booties’ when he entered the house, keeping my floors and rugs clean. No nonsense approach. He assessed the situation,offered the solution then priced it out. Gave us an estimate of the time and manpower it would take then asked when we’d like the work done. We said ASAP since it wasn’t an active leak, he could have a crew here in 3 days. We agreed and the job has been scheduled.
Part 2- 3 days later and Mike and Nick showed up on the earlier side of the promised window. Again, entered our house with the booties on. They originally said it would take about 4 hours when they came for the estimate but they wrapped it up in a little less than 2. They replaced a rusted sewer line and several feeds to it that were also rusted. We had just painted the room white and sealed the floor after some minor flooding in the basement. To look at the space, you never would have known they had been there. They had brought drop clothes with them and set those up everywhere. When they were finished, I couldn't find a single spot on the walls or the floor. Super clean workmanship. Theirs is a number we are keeping in our go to repair book. I highly recommend them. I can see why there are so many 5 star reviews. They earn them everyday.“

“Responsive, informative throughout the repair and reasonable pricing. They did great work!“

“I just signed up for Homeserve yesterday, and am still in the ten day waiting period before the contract begins. Due to a poor distribution of heat affecting our main living areas, I called Homeserve this morning to see if they could dispatch someone on an emergency basis before the big storm this weekend. They were so helpful and got a technician in within 3 hours of my call! John was really thorough, kind, and did his best to address the issue. Turns out we have a major airflow problem, and there will be work needed in the future. He was able to quickly diagnose and rectify the problem for the time being. Thank you for coming to the rescue! Before calling homeserve, we had other people whom we had called who either could not make it due to distance and weather, or who made the original problem a bit worse. I am glad I signed up!“

“I highly recommend L. Graziose for AC replacement! Nestor and Chris provided exceptional service with their professionalism and efficiency throughout the entire installation process. Nestor went above and beyond by identifying the root cause of my old AC's failure.

If you need your AC replaced, L. Graziose Plumbing, Heating & Cooling is definitely the way to go!“
