"We had mold that another company removed. Todd and Dave at Booth Home repair were very professional during the estimate phase and pointed out a few areas the other three contractors did not see. They were punctual, friendly and had a reasonable quote. They started when they said they would, and treated our house as if it were their own. We are more than pleased with their finished work and would recommend them highly."

Universal Windows Direct of Manchester serves all of Central and Southern NH; we specialize in windows, doors, siding, and roofing. We carry our own exclusive brand of windows and siding called Unishield, and we have some of the best warranties in the industry. We are a preferred Owens Corning roofing installer. One of the key points that differentiates our window products from our competitors is that we use only virgin vinyl, built in one solid piece custom to each opening rather than standard sizes modified during installation. This creates a seamless fit that will not bend, crack, or warp over time. We also use the exclusive super spacer in between the panes of glass instead of metal, which is used by most window manufacturers. This amazing material almost completely diminishes any heat or cold transfer within the panes of glass, keeping you and your home comfortable and energy-efficient no matter the season!
"Great. It looks very nice. Two workers very professional"

Making an existing window bigger always requires some construction, but the extent varies by project. Vertical expansions involve less structural work because they often don't affect load-bearing elements. Even so, any enlargement requires removing siding or drywall, cutting framing members, and installing appropriate support. Non-load-bearing walls allow for simpler modifications, while load-bearing walls require proper headers and structural support. A consultation with a structural engineer is advisable before beginning any window enlargement project.
Building permits are required for window enlargement projects in most municipalities. Since enlarging windows involves structural modifications to your home's exterior walls, local building departments need to review and approve the plans. Permit costs range from $100 to $300, though projects requiring significant structural changes may incur permit fees of $500 or more. Additionally, homes in historic districts or those governed by HOAs may need special approvals. Always check local requirements before beginning work.
An average window enlargement project takes between five hours and three days to complete. Simple projects with minimal structural changes might be finished in five to ten hours, while more complex enlargements requiring significant structural modifications could take up to three days. Factors affecting the timeline include the window's location, wall construction, weather conditions, and the need for specialized materials. The process involves demolition, framing, window installation, and interior/exterior finishing work.
