Get answers to common questions about windows services in Sunapee, New Hampshire.
Sunapee experiences cold, snowy winters and humid summers, making energy efficiency paramount. We strongly recommend windows with a low U-factor for superior insulation and a low Solar Heat Gain Coefficient (SHGC) to manage summer heat. Look for ENERGY STAR® certified products specifically rated for the "Northern" climate zone to ensure they are built to handle our temperature extremes and reduce heating costs significantly.
While installations can be performed year-round, late spring through early fall (May to October) is ideal. This avoids the deep winter cold that can complicate sealing and allows for more flexible scheduling before the busy holiday season. However, reputable local installers are equipped to perform interior-protected installations in winter, so don't delay a necessary replacement that could lead to heat loss and ice dam issues on your roof.
In most cases, a simple window replacement where the opening size is not altered does not require a building permit in Sunapee. However, if you are changing the window's structural opening, adding new openings, or working on a historic property or in a protected village district, you must check with the Sunapee Town Offices. A reputable local installer will know these regulations and handle any necessary permitting for you.
Always choose a company licensed by the New Hampshire Secretary of State and insured (liability and workers' compensation). For added assurance, look for providers who are accredited by the Better Business Bureau and have strong, verifiable local references in the Sunapee/Lake Sunapee region. Be wary of out-of-state "storm chasers" who may not understand local building practices or be available for future warranty service.
Beyond drafts and high energy bills, look for persistent condensation or frost between glass panes (failed seal), difficulty opening/closing due to swollen frames from our humidity, and visible rot in the wood sills or frames—a common issue in our climate. Also, check for cold spots and noticeable air leakage during our windy winters on the lake, which indicate the window's insulating and sealing capabilities have failed.
