"Craig the installer did a great job. I was pleasantly surprised by how sturdy the windows were - i picked window source's mid-tier level window. The day after my windows were installed the first storm of the season (snow, rain & ice) arrived and the windows completely performed as they should. I never realized what in eyesore my old windows were until i had these installed. i cant even tell how the wrapping on the windows improved the look of my house! I would definitely recommend window source & i did to a family member. Also, their quote process was quick, 1/2 hour to get a price. Window Source wasn't on my radar while i was requesting quotes on angie's list but they came up as a recommendation & i can't tell you how glad i am I hired Window Source to install all my new windows. A friend had windows installed by a popular chain & Window Source beat the quality and look hands down! If you are like me nervous about hiring a contractor you really know nothing about - i am here to tell you will be happy you hired Window Source. Thank you window source for making my 55 year old house look new!!!"

** Angie's List Super Service award winner in Insulation for 2008,2009,2010,2011,2013,2014,2015,2016,2017,2018,2019,2020,2021 and 2022**Calnan's Energy Systems Inc. has been in business for 40 continuous years and has more than 10,000 completed projects. Specializing in Energy Saving Insulation, Window and Door Installations! We have evolved from a multiple crew to a one crew company. This reduction in size has allowed us to deliver the high level of service our customers have come to expect. Direct supervision by the owner on each and every project, as well as family members involved can eliminate the concern of "Who will be working in my house?" Cost is determined by the job and all estimating is performed by the owner. No travel charges. We are proudly not a Mass Save contractor.
"The roofing company we hired to reshingle our roof suggested that we consider upgrading the attic insulation, and recommended Rob Calnan. Rob came by the day we called him. He was very attentive to our schedule, and went out of his way to fit us in, and through the entire process was readily available and responsive both to cell phone and email. The work took five days, and after each day we received a call about how things went, and what would be done the next working day. This is a family business. Several of his employees are his own children. He takes great pride in the quality of the work that they do under difficult work conditions, squeezing up through narrow openings into cramped, dark attics with little headroom. Rob was very knowledgeable, and enthusiastic about sharing his storehouse of knowledge about insulation. He educated us. He has been actively involved in developing standards in the insulation industry. Three months after the job was completed, when we emailed on the eve of solar panel installation to ask about whether the solar installers should know anything about the insulation, he responded immediately, and said that the solar installers should call him with any questions. We are very impressed by his commitment to his work. The insulation has made the house noticeably cooler."

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.
