"We hired Juan to installed new subway backsplash and remove old peel & stick backsplash from kitchen. Juan mentioned he was a little busy but will be able to take the job on and complete it on a timely manner. Juan installed the backsplash on a Friday evening after 4pm and worked until about 10pm to get the backsplash completed. Juan returned on Sunday after noon to complete the tile work after allowing mortar to dry. However, the issue was Juan did not wipe up access mortal and/or cleaned off the tile. Juan left drops of mortal on our floors (which we had just cleaned from Stanley Steamer). Juan left a few pieces opened-no tile is in those cracks. Juan left the tile backsplash with streaks from the sponge. And Juan did not apply border of caulking to the edges. Juan left tile with streaks and clumps of mortal around our cabinets, on tile and on the wall. After discussing these concerns with Juan he mentioned I was criticizing his work and his integrity. Juan mentioned he has not had a dissatisfied customer who have complained about his work. I mentioned to Juan my OCD kicked in and when we hire someone to do the work the expectation is to complete the work to customers satisfaction and clean up after you have completed your task for the day! Juan mentioned he will return to ensure we are satisfied and complete the work and neither less to say I received a text from Juan stating he will return $100 off the bill that was paid to us and he does not want to work for us! Bad customer services and not acceptable for any customer Very Disappointed"

"I had to replace my old boiler heat as it was not repairable. So I purchased a NEW wall-mounted, modulating gas, condensing, combination Boiler. It replaces BOTH my boiler heater & Hot water tank. The new unit is attached up on wall with a small tank, gas, water lines below. The 2nd pic is where old hot water heater used to sit. Now I have all that extra storage space!! And no need for upkeep & repairs on a big old hot water heater!! The only thing I can complain about was that they were here for 12 hrs!! start to finish. Plus I was here sitting practically on top of a space heater dressed very warmly all day. And of course this was in January 2025 in northwest Indiana. I think this was a 1st time install for them in an older home not a new build. I would have rated them as a 5 star if not for the LONG DAY it took to be installed. They all were very nice, kind & cleaned up their mess. They brought large painter cloths to put down on floors due to going in out in the snow also."
