"I contacted All Ways for window cleaning, then asked about gutter cleaning and treating the roof for moss. Brian got back to me within the hour. I would hire them again in an instant. Derek did all three tasks, was prompt, professional, with high commitments to quality and customer service. He finished after dark and came back the next morning to finish some slider door tracks he couldnâ t do well enough in the dark. I may never wash my own windows again, the price was so reasonable and the work so good. For sure, Iâ ll have a hard time convincing myself to prep my own gutters for winter for the same reasons. :)"

"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

Whether or not new windows increase property taxes depends on where you live and by how much your upgrade increases your home’s value. Smaller projects likely won’t result in increased property taxes, but it’s always a good idea to err on the side of caution and check. Contact your local county appraisal department for the most accurate information about property taxes in your area. 

Bay windows are supported by braces and industrial strength cables, often at the top of the window but sometimes at the bottom. The bay window may need buttress supports if installed on the second floor. Wood screws on the interior also hold the bay window in place. Bay windows are heavy and need proper support to prevent sagging and wall damage. You need to ensure that the support system can hold the weight of the window and the roof cab over the window.

Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you’ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you’re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

Yes, you can replace the frame around a window by completing either a partial replacement or a full replacement. With a partial replacement, your window specialist will remove the trim around the window and replace or repair just the damaged portion. For a full replacement, your tech will need to remove the window, replace the frame, and then reinstall the window.
