"Second time hiring Action windows and I wish I could hire them for everything. Where it counts us if you have an issue and how it's handle. Small. Problem was handled asap and they even sent manufacturer out right away to repair it. Said they would do it themselves if necessary. Wonderful superb company to work with. You won't be sorry. I look forward to siding next with Action windows and siding."

"Can't say enough about them. Punctual, clean,and courteous - and I am very anal about the clean part! Windows look beautiful! On a side note there was a closure of a major highway on route to my house that tied traffic up for miles - they were 15 minutes late and apologized profusely. I was expecting them to be much later due to the closure, so they really did make every attempt to get there on time. Great people and great company and now consider having them install siding and gutters

Windows FAQs, answered by experts

Most homeowners prefer to service their windows during the spring or fall when temperatures are the most bearable, and having large openings in your wall won’t drastically increase your heating and cooling bills. However, while these seasons are the most convenient, you’ll also tend to pay more for window repair due to the increased demand. If you want to reduce labor costs, consider making window repairs in the off-seasons. Avoid waiting until the heart of winter to do repairs, though, as you could run into leaks and heat loss issues.

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.

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.

Yes, window manufacturers and installers can mull together three windows—or even more—for a more impressive appearance that lets maximum natural light into your home. However, you may have constraints regarding the total size of the wall opening. Your installer can help you determine what size wall opening is safe based on the structural load. In most cases, you can install additional supports to span the opening, like a steel I-beam, but this drastically increases the installation cost.

The maximum protruding distance allowed for a bay window is determined by its flank angles. 30-degree flanks can extend about 13 to 14 inches. If the angle is 45 degrees or larger, then the bay window can stick out about 19 inches. If the window extends too far out, it would cause structural instability and safety concerns.
