"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"I cannot say enough good things about FCB. Max bends over backwards to make sure the customer is completely satisfied. I’ve never had a more responsive and conscientious contractor. We had FCB replace all of our windows in 2022. We were so impressed by the quality work and price that we called them again to replace our storm door, front door, sidelights and shutters. Great experience. Highly recommend!"

Windows questions, answered by experts

Folding window installation costs about $1,600 on average, ranging from $500 to $3,000. The cost factors of this project include the size, the type of folding windows, the number of panels, and the type of glass. Different types of folding windows include:

  • Standard folding window: $200 per linear foot

  • Glazed folding window: $240 per linear foot

  • Standard folding window and swing door: $1,000 per linear foot

  • Folding window and sliding door: $2,000 per linear foot

Bay windows are expensive mostly because their above-average size means higher material costs. Unlike bow windows, most bay windows also include casement windows on either side of a picture window, and the opening mechanisms for casement windows drive up costs. You’ll also pay higher labor costs to install a bay window, as you’ll often need multiple technicians to lift the window into place.

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.

Picture windows are still in style, even though they are one of the oldest types of windows. Other windows, like single- or double-hung windows and casement windows, have increased in popularity because they can open up for fresh air. However, homeowners still love the way a picture window can frame their lush outdoor garden or other pleasant neighborhood views.

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.
