"Sean was awesome from the get-go. He was incredibly responsive, answered all my questions, and gave me a "best guess" number over the phone even before he had seen the window that was being replaced. He then showed up with his team (exactly on time) and they did the measurements and were right on with their initial estimate. The glass was a few weeks out to order (given the size) but right when they got it, Sean called and set up a delivery. Again, they were right on time within the window that they said for doing the install and were quick to get the old window out, and the new one put in place. It went perfectly, and it looks as good as new. I will use them again any time I have anything glass related 100%. Thanks guys."

"Four of the five windows ordered were fine. One window did not fit (by wide margin) due to measuirement error. Champion has not shown any of the expected urgency about correcting the problem."

Windows FAQs, answered by experts

Vinyl window frames are by far the most popular window frames in modern homes. Many favored vinyl frames due to their affordability, durability, energy efficiency, and various colors and styles. Single-pane vinyl windows range from $200 to $900 per window, and double-pane vinyl windows range from $400 to $1,500 per window.

In some cases, you might need a permit for a window replacement, which is hard to get if you’re not a professional contractor. You should probably just hire a window replacement company in the first place because the job is complicated and can be dangerous for the average DIYer. You may not even save any money doing it yourself because contractors purchase materials wholesale.

Use a high-quality caulk with silicone around your windows, as it’s waterproof and shrink-proof. Or, you can use a caulk consisting of polyurethane or acrylic if you want to be able to paint over it. Caulk made from silicone is not paintable. Avoid using inexpensive caulk that has a resin or oil base. These caulks will not last long and may shrink and pull away from the window as temperatures go up and down.

Windows provide light and a view of the outdoors without the inconveniences that the outside world can come with, like noise, rain, snow, and unpleasant scents. Vinyl windows also provide energy efficiency thanks to their insulating properties, keeping your home at its coziest temperature no matter what season it is. They’re also excellent noise dampeners, so your interior space can stay calm and quiet.

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.
