"The contractor scheduled our initial meeting almost immediately. When he first arrived he removed the window, that was broken, for measurement. He noted the size and explained that it would be ordered and should take 7-10 days. He followed up and let me know the progress. Once window was completed by manufacturer he scheduled the appointment to replace the window, keeping me updated and aware. He installed the window on the day he scheduled and the window looks great. I would definitely Ro again for any window needs and would recommend him as well."

Windows questions, answered by experts

A common way to modernize arched windows is to install interior window treatments that allow light through the curved portion up to and let you cover the bottom portion for privacy. You can also install plantation shutters to make an arched window look more modern. From the exterior, arched windows can appear outdated if they’re coupled with ornate trim, so toning down the decor can make your window look more natural with a modern design.

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.

Yes, triple-pane glass windows cost more than double or single-pane windows. You’ll eventually get that money back in energy savings. Depending on how much you pay for the installation, you could recoup your costs in 10 to 20 years. Triple-pane windows have extra layers of glass, which improve insulation and help save money in long-term heating and cooling costs.

While plywood will keep winds and debris from shattering your windows from the outside, window film can help protect your windows from the inside. Window film can keep a window from shattering. If your windows break, the film can hold the shards of glass in place, reducing the risk of cuts.

While you may sometimes see window film marketed as "hurricane window film," note that it doesn't provide sufficient hurricane protection on its own. It's no substitute for plywood, storm windows, or hurricane shutters.

Costs depend on hardware type, labor rates, and the extent of the repair.
