"From beginning to end this was a complete good experience. John came out and showed us the window and explained the process. After doing my research I have found the windows he uses to be excellent quality. Ordered the windows, 12 weeks to the date they were installed. The install was done in half a day. They team was very clean, helpful and complete. They answered all my questions and even let me watch! We noticed a difference within hours of sealing up the windows how cool my second story remained with the Energy Efficient windows in. I cleaned all of them with an easy process of sliding the clips and opening them. What a dream window and only wished we had done this ten years earlier. The windows were 29 years old, solid wood and clad. From the outside you can hardly tell the difference. These were a great purchase, and we are looking forward to having the other 13 windows done with Best Windows."

Windows FAQs, answered by experts

Hopper windows aren’t flawless when it comes to keeping rain and debris out of your house because if there’s wind pushing the precipitation, it could easily get in through the open space. On top of that, hopper windows aren’t potential escape routes the way regular windows are in case of a fire or emergency. If that’s a priority or need, it’s something to consider when choosing a window type.

To lower your home’s humidity level overnight, you can open your windows when the air is less damp. This tactic allows air to circulate around the window, preventing condensation from forming. However, you should consider the disadvantages of leaving your windows open overnight, including safety risks and pest intrusions.

The best time to remove and restore old windows is during temperate weather. Late spring and the early onset of winter are ideal seasons. While summer has its challenges (e.g., bugs, heat, and dust), it’s also a good time to do restoration work. The worst time to restore old windows is during the winter, especially if it is particularly cold and snowy.

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.

Yes, every window needs a lintel. The lintel is necessary for redistributing the load above the window to the walls around the window. Windows aren’t meant to support a load, so lintels are an important part of a window installation. If you go to replace your windows and discover there are no lintels, you may need a window company or structural engineer to install lintels for your new windows.
