"We just needed the pane in one window replaced. They came to look at it the same day I called. He measured and ordered the window in less than 10 mins. As he said, 10 days later the window pane arrived. They came and installed the window that day in less than half an hour. The service was great, timely and affordable. I will definitely remember them for any future window replacements."

Windows questions, 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.

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.

Double-pane windows cost an average of $900 per window. The price range for double-pane windows goes as low as $300 and as high as $4,500 per window. This window type differs from single-pane windows by spacers separating the panes and helping strengthen them while holding them in place. A gas like argon or krypton typically fills the space between the panes.

Depending on size, material, and labor, two windows can cost between $600 and $1,600.

There are several downsides to choosing casement windows for your home. Firstly, casement windows can cost significantly more than standard windows—especially if you need to install custom windows. If you plan on installing window AC units, then casement windows aren’t the best option, as it can be difficult to fit an AC unit into windows that open sideways or outwards. 

The hinges on casement windows also pose a higher risk for break-ins, as rust and wear and tear can make the hardware easier for burglars to break into.
