Window Replacement Services in Connecticut
Upgrade to energy-efficient windows that reduce drafts, lower utility bills, and enhance your home's beauty. Professional installation with meticulous attention to detail.
Windows That Perform & Impress
Connecticut's extreme temperature range—from bitter cold winters to humid summers—makes energy-efficient windows essential. Cold winters can drive heating costs through the roof when older windows let warmth escape. Quality replacement windows can reduce energy bills by up to 30%, and proper installation for New England's harsh climate ensures a tight seal that prevents drafts and keeps every room comfortable year-round.
At Hoffman Exteriors, we help you select the right windows for your home's style, your performance needs, and your budget. Then we install them with the precision that ensures they'll perform beautifully for decades.

Windows for Every Home

Casement Windows
Crank-operated windows that swing outward for maximum ventilation and an unobstructed view. Excellent energy efficiency with tight seals.
Bay & Bow Windows
A bay or bow projects past the wall, so it adds floor area and light that a flat window cannot. It also carries its own load: the unit needs a supported seat and a properly flashed roof above it. Most of the bay leaks we are called out to fix are failures of that little roof, not the window.
Picture Windows
A fixed sash with no operating hardware, so the glass area is larger and the air-seal is better than any window that opens. Used where you want light and a view rather than ventilation — paired with casements or double-hungs on either side.

Connecticut window code, and how to read a quote
Replacement windows are specified by performance numbers, not by brand name. There are three that decide whether a window suits a Connecticut house, and all three are printed on a label you are entitled to see before you buy.
Design pressure, and why a good window can still leak
A window's design pressure rating describes the pressure it can take without leaking or deflecting. It is a property of the unit, its size, and how it is anchored and flashed into the opening — which is why an excellent window installed badly still leaks, and why the install detail deserves as much attention in a quote as the product name. Ask how the sill will be flashed and how the unit will be shimmed and fastened.
Connecticut is in the ENERGY STAR Northern zone: U-factor 0.22 or lower
Under ENERGY STAR version 7.0, which took effect in October 2023, windows in the Northern climate zone must have a U-factor of 0.22 or lower and a solar heat gain coefficient of at least 0.17. All of Connecticut is in that zone.
The U-factor is heat loss, so lower is better. The SHGC minimum is the one that surprises people: it is a floor, not a ceiling, and it is there on purpose. In a heating-dominated climate a window that blocks too much solar gain is costing you free winter heat.
Coastal exposure changes the hardware, not just the glass
On homes near the Sound, salt reaches locks, hinges and crank mechanisms long before it troubles the glazing. Corrosion-resistant hardware and a properly sloped, flashed sill are what keep a window working in year fifteen rather than year five.
When window work needs a permit, and when it does not
Most Connecticut towns do not require a permit for a like-for-like replacement where the opening size does not change. A permit is generally required if you are resizing an opening, cutting in a new window, or altering structure such as a header.
Historic districts: like-for-like is exempt, changing material is not
Several of the towns we serve have local historic districts, and the rule that matters is narrower than most homeowners expect. Under Connecticut General Statutes Sec. 7-147f(a) you do not need a Certificate of Appropriateness to put the same material back on. You do need one if the material type changes — slate to asphalt, wood to vinyl — or if the configuration changes. Ordinary maintenance and repair in matching materials is not subject to review at all.
That single distinction usually decides whether a project starts on schedule or waits for a commission meeting, so it is worth settling before anyone orders material.
