"We replaced the windows in our 1933 home through the services of MadCity Windows. From the initial contact with their sales representative to final installation, the company provided top notch professional work. With the draft from the old windows and the cold of the glass, we are already saving on our energy bills. Our house had old, large windows, so they had to be custom made. As an industrial designer and interior designer, we find our windows to be of excellent quality."

"I called and the next day the sales rep came out to our building with samples to pick from and she was very informative about the products and professional. I had to call back in because i did not count the right number of windows to be done. And again the sales rep was accommodating and was able to add the windows 3 days before installing. Also was able to schedule a sunday Installation when the lab was closed. The installer was here early, very courteous , professional and efficient. I was able to leave him to do his work so i could get my tasks done also. Exceptional service"

Windows questions, answered by experts

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously. 

When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.

Wood windows will help keep an old home's charm, but they are more expensive and harder to maintain. Vinyl or fiberglass windows offer the best benefits in terms of durability and ease of care while still somewhat blending into the look and feel of an older home.  If the vinyl or fiberglass looks too out of place, consider adding shutters or something similar. The cost of plantation shutters is about $2,990, but the charm they bring to a home is unmatched.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

There are many signs to look out for that tell you it’s time to replace a double-hung window. If the window is drafty and inefficient, you may need a new window to block out air leaks and keep your utility bills from skyrocketing. Other signs that it’s time to replace a window include foggy glass, soft or broken window frames, or window sashes that won’t open or close easily.

A window may fail because of age, defective mechanisms, or moisture. Depending on the issue, the window may be fixed with simple repairs. Otherwise, you’ll have to invest in replacing it. You can avoid damaged windows but keeping up with window maintenance.
