Zephyr installed a new storm door for us. This is the second time we have used their services and have been happy with their workmanship both times. The staff is professional and courteous as well as knowledgeable. We love working with Kim in the office and Dave our installer. Couldn't ask for better people. Service: General door installation

Zephyr installed a new sliding glass door to our screened porch. Daryel was the sales consultant and he did an excellent job throughout the process. The door arrived on schedule and the install team was thorough and courteous. There was a minor follow up issue that was handled in a timely manner. I would definitely use this company again for future work.

I had such high hopes that we'd have a great experience with Zephyr. They came out to do an estimate and I was told it would be 14 days for us to receive an estimate which is Completely reasonable and standard. After two weeks, I didn't receive a quote so I call to follow up only to learn they didn't have my email address on file. I provide it and two weeks later still have yet to receive quote. If its this hard just to get a quote -I can't imagine how communication or any follow up with project concerns would be a total nightmare. Definitely going with the "little guy" a much smaller company that despite not having support staff manages to communicate in a timely manner.

Amazing work on removing/installing some double-wide shed doors. Everything looks great, works well, and was finished very nicely. Two man crew did the install, and cleaned up afterwards to near-perfection. Could not have asked for better work: very satisfied! Service: General door installation

We had a front deck replaced and a new front door installed. The construction team, lead by Bill, were great. They were professional, knowledgeable, neat and quick. The deck looks so sturdy and well made, it seems it will outlast our home. Brad Thomas, our salesman, was friendly and easy to work with. I would definitely hire them again. There is much work to be done at our house.
