Jeremy Miknis

Great company to work with and friendly and knowledgeable techs

Kenneth Iman

Normally I fix my own plumbing. But this leak was 16' above ground inside an outside overhang. Trenton from Haller had to go through a lot of effort and ladders to fix the leak. Expertly done and friendly staff. Significant water damage and not a pleasant experience but Haller came to our rescue. I highly recommend them!
Edit: Used them a second time for a bathtub faucet replacement. Daniel did top quality work and was a joy to encounter. This was a fairly difficult repair. A quality repair. The cost was also less than half the estimate of a local "handyman".

Billy

Technicians were very professional and knowledgeable .

Eric Musser

Don did an excellent job on our Geo system repair. He is very contentious and always a pleasure to work with.
