Year-Round Energy Savings
Wisconsin winters are tough, and drafty windows are a major source of heat loss.

Stop heating the outdoors and start enjoying lower utility bills and a more comfortable interior climate.
Precision Installation & Finishing
A great window is only as good as the installation. Our carpentry background means we don’t just “pop” windows in; we ensure the rough opening is solid, the insulation is tight, and the interior and exterior trim work is flawless. We handle the full carpentry scope, ensuring your new windows look like they were part of the original design.

At Bontrager Exteriors, we specialize in fenestration solutions that blend security with aesthetic appeal.
We offer a wide range of styles, including double-hung, casement, bay/bow windows, and sliding patio doors. Whether you need a simple “insert” replacement to preserve existing trim or a “full-frame” tear-out to maximize glass area, our team has the expertise to execute the job correctly. We also install stunning entry doors that serve as the focal point of your home’s facade.
With over two decades of experience, we ensure that your new windows and doors operate smoothly and seal tightly for decades to come.

… It was an unusual experience. Mark said the crew would be there at 8:00 am, and they were! … The work was done at a reasonable price and completed within budget. The property was free of any waste once they were done. The whole project was completed by 5:00 pm. I can’t say enough about what a pleasure it was working with Mark and the crew!!!
We chose Allen Bontrager for the metal siding and roof on our lake house, and it’s absolutely beautiful. The team does timely, quality work, and we could not be more pleased with the finished product. We highly recommend their metal siding and roofing products, and you could not ask for a more professional team. Thank you, Allen Bontrager Carpentry!
They did an awesome job on our roof. They worked very hard and they got it done as they said they would in the same timeframe that they had told us I would totally suggest hiring them. They do awesome work and great guys. Very nice!
Everyone we interacted with from Mark who came out to give our estimate to the entire crew who were polite, worked hard and fast, and were very helpful with any questions. The new roof and door wrappings look great and the price was very fair. We were very happy with the entire operation and did already recommend to a friend and we will use them again when needed. Great job!
Allen Bontrager Carpentry did a fantastic job for us after a tornado hit our home.
