I can’t say enough good things about Disilva Plumbing and Heating! They’ve helped me with several plumbing repairs around the condo, and every time their work has been top notch. Most recently, I had an emergency issue, and they came out right away. Al and team are always professional, friendly, and efficient. It is rare to find someone so dependable and honest. I highly recommend Disilva Plumbing and Heating for any plumbing needs, big or small.
Al and Toby were ever so kind and able to fix my furnace issue. I can’t thank them enough for all they did especially with all the time and effort they put into it. Highly recommend them!
Toby came out the same day to check on a leak that we were told that we had in our kitchen stove, ran 3 different tests just to be safe. Super professional and quick, will definitely be calling again if needed!
