"I called Mike after we discovered a leak in a window was not taken care of by installation of a new window. The project was open-ended and required investigation of the source of the leak which wouldn't be determined until the siding was removed. Mike was thorough in his investigation of the problem and up front about pricing being a bit of an unknown and gave me a minimum bid which we agreed to readily. Once the siding was removed the source of the problem was quickly diagnosed and fixed. Mike gave us documentation for the window company and advice on how to proceed. He will return to address further outdoor water damage once the rest of the windows have been replaced. Mike is honest, knowledgeable, and capable of handling issues that others couldn't even begin to address. We are grateful for his expertise and guidance and will be using him in the future."

"I had them install all of the windows in my house. Then I also referred them to my son in law and he had windows replaced in his house. I know what the price of a window is and quality, but what I got from them was not only a good price. It was the exact windows that I wanted. They finished the inside of the windows with a molding and I had to do no work when they left. I have like three windows on one side of the bedroom and then there's the corner and then a window on the other side of the bedroom. They even covered that with vinyl so I don't have to paint the anymore. They were fast, efficient, they took everything away. They were nice and polite. It was just a joyful experience. I'm thinking of getting new doors for the back of the house. They sell doors too. I replaced 20 windows, three of which were picture windows. The picture windows are more pricey. They were about $1500, but this includes installation. I think the casement windows were about $5,000. But you have to think this was a few years ago. But it was just the quality of the work. <br /> <br /> I started off with a window that was cracked, on the add-on on my house, which has 7 windows. After they put in my broken window and I'm looking at the other windows. I said well I guess we'll do the rest of them. So I started off with what I had to do, and I ended up doing the whole house."

"They did an awesome job! Sales and installers were all professional from start to finish !! They were on time and finished the job quickly and did a stellar job."

"The entire process went smoothly. The reservation went quickly, once we paid an extra $200 to reduce the pickup window to 3 days. The pickup and drop off process also went well. The car was returned in the same condition we left it. We would recommend using United Freight."
