"We had several windows and doors replaced and I was really impressed with the new windows and doors as well as the professional installation by Perry and his crew. They made sure everything was square, clean, and caulked. Great job! I highly recommend Metropolitan High Performance Windows."

Customers say: True professional

"After 20 years of neglect on my part, the windows in my house are now unbelievably clear thanks to the work of Justin and José from Clear Glass. I can recommend them without reservation. The two men did a first-class job washing the windows and cleaning the screens and the windowsills, both inside and outside. When I pointed out to Justin that two of the windows were particularly dirty, he told me that the dirt was actually discoloration caused by an issue with the argon gas insulation between the double-panes. He then told me that I should ask the manufacturer to replace the two damaged windows. In addition, José realigned three of the windows that had come off the tracks on either side of the panes. The cost of the job was very competitive, especially considering the time it took to remove so much dirt. Justin also gave me a seven-day guarantee to come back and redo anything that he had missed or that needed attention. (I did not need to take advantage of that service.)"

"What a great investment! The quality of the windows is the best I’ve seen. We are returning customers - Brothers Home Improvement replaced all of our windows and two sliding doors in our home about 15 years ago. However, we held-off on replacing out ten bay windows, until now. The two gentlemen who replaced our windows were complete professionals and left the entire work area “spotless”! These windows are worth it and the service provided is excellent! Thank you!"

Windows FAQs, answered by experts

The rough opening refers to the framed space in the wall where the window will be placed. That means the full size of the space will be filled with both glass and frame once the new window is installed. For a standard window, a rough opening adds 1/2 inch to 3/4 inch to both the length and width.

Your new windows may let in more noise than your old windows because they are not the right size or they were installed improperly. Improper installation, or choosing windows that are too small for the opening, can create gaps around the window that let in noise.

Another factor could be the STC and OITC ratings. If your new windows have lower ratings than your old windows, this means they have lower performance when it comes to dampening noise from the outdoors.

Yes, window manufacturers and installers can mull together three windows—or even more—for a more impressive appearance that lets maximum natural light into your home. However, you may have constraints regarding the total size of the wall opening. Your installer can help you determine what size wall opening is safe based on the structural load. In most cases, you can install additional supports to span the opening, like a steel I-beam, but this drastically increases the installation cost.

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.
