"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

Yes, egress windows must meet local building codes for size and accessibility. Professional installers ensure compliance.

The visibility through tinted house windows depends on the lighting. During the day, when it is brighter outside, privacy film prevents people from seeing into your home. However, this effect reverses at night. If you have lights on inside, it becomes brighter indoors than outdoors, allowing people to see inside. To optimize privacy, you can select from various shades of film, ranging from lighter to darker, which affects how much is visible from the outside.

The key difference between a hung window and an awning window is that hung windows (including single-hung and double-hung versions) slide vertically to open and close. In contrast, awning windows have a hinge at the top and open outward at an angle. You can use both types of windows throughout your home, but awning windows are best suited for kitchens and bathrooms.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

A double-hung window features two operable sashes, meaning it has an upper window part and a lower part that can both open to let in fresh air. A picture window has one fixed glass panel that doesn’t open. Double-hung windows cost about $200 to $2,500, while picture windows cost about $200 to $1,900.
