"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.

Window capping costs between $1 and $2 per linear foot. Since your average window size is 24 by 36 inches, you’re looking at 10 linear feet in total, or $10 to $20 per window. Labor adds another $30 to $100 per hour to the project. If you have custom windows, you’ll spend more to have your windows capped. Fiberglass tends to cost more than vinyl and aluminum, while vinyl costs the least but has the shortest lifespan and may have a higher long term cost.

When specifying window sizes, manufacturers use a standard four-digit code system. The first two numbers represent window width, and the last two represent window height. For example, a window with a code of 2917 has dimensions of 2 feet, 9 inches wide by 1 foot, 7 inches high. Windows with even dimensions include zeros as placeholders. For example, a window that is 5 feet wide by 2 feet high would have a code of 5020.

If you live in a colder region, consider installing double- or triple-pane windows with low-E coatings, which can trap heat and keep your house warm. In hot areas, windows with reflective coatings and insulated frames help keep cooling costs down. If you experience a lot of extreme weather, then impact-resistant glass might be a worthwhile investment. 

Shatter-resistant glass will ensure that even with a high impact, the glass of your window panes is less likely to break. If you’re looking for a more low-cost way to prevent vandalism, the most traditional answer would be to board up windows with a strong plywood sheet. Adding security cameras is also a surefire way to ward off potential vandalism.
