"Bill Millis did an excellent job removing our original windows and installing new Pella windows. He also worked hard to allow us to keep our existing aluminum siding, which was no longer available. I have provided his contact information to several neighbors and friends."

Windows FAQs, answered by experts

Bay windows are supported by braces and industrial strength cables, often at the top of the window but sometimes at the bottom. The bay window may need buttress supports if installed on the second floor. Wood screws on the interior also hold the bay window in place. Bay windows are heavy and need proper support to prevent sagging and wall damage. You need to ensure that the support system can hold the weight of the window and the roof cab over the window.

Yes, with modifications or the use of adapter kits for tricky placements.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window.
