I had hired a contractor to help remodel a duplex. After a bad experience I started working with Dahl Mechanical. John and his team have done miracles. Open doorways and adjusted sinks for a handicapped client. They installed an automatic door as well. Some of the work John did included, hanging new light fixtures, installing ceiling fans, installing new flooring, installing tile, installing sink and sink fixtures. They updated a wooden ramp to make it more accessible and safe. Looked at my furnace, made an upgrade to my wiring, did cement work and even fixed the running toilets. John's knowledge has been a wonderful resource and they are always dependable, trustworthy and quick! I will continue to use his services and would hire them again and again.
