"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."

"Perfect Choice Exteriors was fantastic. They helped us find some specialty windows for a new addition to our home. We added a new bay window and an octagon window in the living room. I was surprised by all the options and their ability to make custom windows. Products were expensive but worth the cost!"

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"Hired to replace 2 window screens on the second story of our home. Val found another one that needed replacing, and he did that one too, for no additional charge. He also fixed our kitchen light so that it stopped blinking when we first turned it on. Friendly, courteous, punctual and professional. Will be hiring again."

"Costly! Incorrect measurement of basement windows delayed installation by months. I had to recaulk inside and out, to reseal. Broken window-slider handle. My continuous calls for window installation yielded, no apology or price break. Once installed payment notice immediately mailed with threat of collections because contract states payment at time of completion. No follow up on warranty, servicing etc of my crawl space encapsulation as promised to me at time of signing contract."

Windows questions, answered by experts

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.

Garden windows last about 15 to 30 years, depending on the materials, ongoing maintenance, and local climate. Fiberglass and wood windows tend to have the longest life spans as long as you keep up with cleaning, lubricating, and refinishing them. Make sure to inspect your windows about once a year for signs of trouble, like worn-out seals, frame damage, or cracks in the panes.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.

Whether or not you need permission to change the windows in your house depends on your local laws. If you’re enlarging an opening or installing a new window and need to make structural changes to the house, you’ll need a permit. In most locations, you won’t need permission if you’re just replacing a window with another window of the same size. The window installation company you work with will be able to help you navigate any planning permits you may need.
