"We’re very happy we chose Matt and Tartaglia Renovations for our primary bath renovation. It was a big job—removing the original 1960s bathroom and expanding the space for a larger shower and more functional layout. Matt and his team were up for the challenge, helping us map out all the details to bring our vision to life. They paid attention to small things, like tile alignment, to achieve the modern look we wanted. When changes came up, Matt was communicative, transparent, and always kind. He addressed any questions or concerns quickly and thoroughly. The whole team were very considerate of our home and mindful of the other renovations we had going on. The best part is that the end result is a bathroom we absolutely love. We’d choose Tartaglia Renovations again without hesitation. They've definitely earned our trust."

"LVP looks great and tile in the kitchen look great but the trim and baseboards were not finished and I had to have another contractor come in and install them. The stairwell was sanded and stained and I was told they could match the stain for the stairs to the LVP and that wasn’t true either. The stairs came out pink. Now I’m having another contractor come in and fix. I would not recommend to a friend."

Tankless water heater installations FAQs

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
