Get matched with top tankless water heater repair pros in Fairview Village, PA

"Within 4 days I had a new tankless water heater installed. Adam and Brendan went above and beyond. Thanks!"

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Good communication, very pleasant, quick service. Don was extremely helpful and easy to work with, even after i picked out the wrong type of replacement water heater and he had to return it! Would use again."

"The workmanship was very professional and cleaned up afterwards. Wouldn't even know they were here. Billy did an excellent job with the removal and instillation of a new hot water heater. Brought the instillation up to code by adding a drip pan and expansion tank. I have them coming back to replace valves for washing machine and installing shutoff valves."

"Quick response on a Sunday after my hot water heater failed, with ValDel able to supply the brand of water heater I was looking for. No one likes putting out the kind of money that this type of emergency repair requires, but I was able to negotiate significantly down to almost match a verbal quote that I had received earlier in the day. Jason was an excellent technician, very courteous, and completed the job quickly. I would definitely use ValDel (and Jason) for future needs."

"Did conversion from Oil to gas and installed new water heater and boiler. Work was fantastic, easy to do business with, and was a great help in the entire process from beginning to end."

"They were summoned by my Home Warranty Company. The 75 fee is my required co-pay from the warranty co. My hot water heater is 15+ years old. They welded a pipe on the bottom of the leaking heater. Work was done right, it stopped leaking. 2 weeks later they were back for another leak, the relief valve. The hot water needs to be replaced but my warranty co wants it repaired if that is possible, so that's not Clear Water's fault. After the 2nd repair, we probably could have had it authorized for replacement but the "items not covered clause (again not the fault of Clear Water, set by warranty co) would have cost 400 - 500 dollars. The heater is gas powered and we would like to convert it to electric. We have an estimate of 895 for the whole job, and the type of heater we want. I think there charges for the extra items are high. There work and professionalism and punctuality were good but I can get that elsewhere for less.
