"I checked out other companies and their craftsmanship was very poor compared to your men. The Pella windows your men installed look great, and my wife loves the built-in blinds. I checked with 2 of my neighbors, who have the same cluster home, on their heating expenses for the winter so far. My heating bills are more than 30% below theirs. My house seems to be more comfortable and evenly heated during the winter, and I save money." H. Leslie Baron Pella windows and James Hardie fiber-cement siding Bloomfield Hills, '07

Together, we were able to pick the perfect Pella windows and doors to compliment the overall design scheme of the project. Phase Two of the job involved reconfiguring and renovating the interior of the home and to build a new Florida room. Again, we hired 21st Century Building Company."
