Thebco has been out to our home several times replacing windows, siding, entry door and a patio door. It's nice to be able to pick up the phone, call the Thebco office and know you don't have to fear a pushy sales pitch. We have dealt with both Steve Bobeck, the owner and Bob B. sales rep. Both of these gentlemen have been great to work with, very professional, patient with our numerous questions we tend to ask and responsive when we made contact with them. Replacing windows and doors can be a big investment and we have felt very confident in the quality of Thebco's products and install crews. We had double hung windows replaced this past fall due to some very leaky, cheap replacement windows that had been installed 10 years ago. Mike, our installer was promptly on time and got to work immediately.(Actually, Mike has been to our house on previous installs over the past 8 years. It's great to know that the installation is not farmed out to any Joe Blow and Thebco has had the same installers for years) The installation went smoothly and there was no mess left behind. We love our new windows, they work great and I know I have saved money on my utility bills. Thebco installed our patio door about 8 years ago and that has been one the best investments ever! We went with the 3 panes of glass for extra insulation and sunscreen. Our patio door gets baked all summer long and we don't feel the heat at all, not like we used to. It's a solid patio door that gets tons of use and still works like we had it installed yesterday. We had Thebco install a new entry door with 2 side lites a new storm door with a full glass view. What a major improvement on the utility bill - It was worth every penny. It was hard to select which door and lite set to go with because there are so many options. Again, Mike did an awesome job installing the door and storm door. This door was installed roughly 6 years ago and is living up to all expectations. Thebco sided the front of our house years ago and again we had the same great service. The siding job went smoothly, the installer was very courteous and was careful not to leave nails in my flower beds or lawn. The siding to this day still looks great. One time that we had to call the office for a door knob issue, they set the appointment right away and the service manager was out the next day. He was on-time, professional and adjusted the door knob in 5 minutes. Quick and easy with no hassle. That is my kind of service! We have no issues in recommending Thebco. The entry doors, windows and siding that they offer are of excellent quality plus you are working with a family owned business that has been in Madison for years. Thebco doesn't sell cheap products and you never have to worry about who is at your house doing the installation.
