After some unexpected challenges with the way our home was built, our installation crew quickly and efficiently adapted to make sure our windows and door were installed with expert care. Every time we see our new beautiful picture window we are left breathless! And our beautiful front door is the perfect upgrade for the look of our home. Thank you RBA!"

Windows questions, answered by experts

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Typically, a bay window is, at minimum, 42 inches wide. That said, you can always design a custom bay window that is smaller—box bay windows are usually less than three feet in width and are ideal for smaller spaces.

The gas between window panes, typically argon or krypton, acts as a barrier to heat transfer. This means it helps keep your home warmer in the winter and cooler in the summer by preventing heat from passing through the glass. This gas layer also reduces condensation by stabilizing the temperature across the window and helps minimize noise. Essentially, it’s all about improving energy efficiency and comfort while lowering those utility bills.

A window may fail because of age, defective mechanisms, or moisture. Depending on the issue, the window may be fixed with simple repairs. Otherwise, you’ll have to invest in replacing it. You can avoid damaged windows but keeping up with window maintenance.   

The most common types of window frames include frame and sash, metal or aluminum frames, composite frames, fiberglass frames, vinyl frames, wood frames, glass or glazed frames, and insulated frames. Frames can also be categorized by operating types, such as awning frames, single/double-sliding frames, fixed frames, casement frames, and single/double-hung frames.
