Home Window Replacement

Choose home window replacement from the experts at Sullivan Contracting CT and transform your space. Our selection of wood, fiberglass, aluminum and vinyl windows are designed and built with exceptional detail and fit virtually any home and budget.

Vinyl Windows – Durable, inexpensive, and easy to maintain, vinyl window frames are made from extruded and tempered PVC and are available in a broad selection of colors. Most types of vinyl frame are designed with a hollow core to reduce heat loss and condensation. Over time, low-quality vinyl frames may experience air loss.

Wood Windows – The traditional material for window construction, wood provides excellent insulation against temperature and condensation while offering classic natural beauty. Wood windows are generally sold unfinished, allowing the purchaser to stain or paint them to taste. Wood frames tend to have a shorter operating life than synthetic materials, and provide limited fire resistance.

Fiberglass Windows – Much stronger than wood, but able to be painted, unlike vinyl. Fiberglass offers a blend of natural product appearance and synthetic material durability. More rigid than wood or vinyl, fiberglass frames rarely experience warping or sticking. Many manufacturers have embraced glass recycling techniques in fiberglass production, making it an environmentally responsible option.

Aluminum – Lighter, more durable, and easier to handle than wood, aluminum windows are long-lasting and available in a wide variety of colors. Aluminum provides superior weather resistance, but generally requires a layer of vinyl or foam composite to reduce heat loss.

Four Signs that it’s Time to Replace Your Windows.


ROTTING WOOD – If a screwdriver can sink easily into the wooden frame, then it likely needs replacing. A damp environment is especially hard on many types of older all-wood or wood-based frames.

ENERGY EFFICIENCY – Extremely high utility bills? Your windows could be to blame. Windows are thermal holes. An average home may lose 30% of its heat or air-conditioning energy through its windows.

COMPROMISED GLASS – Fog or moisture build-up inside the windows glass panels. If the glass shows visible gaps between the pane and the sealant or frame, or if the glass is physically damaged by cracks, chips, or holes, the window is no longer an effective insulator.

BROKEN & OLD WINDOWS – Operating a compromised window may further damage the existing window, as well as create a security hazard for your home. Repairing or restoring old windows is almost always an option, but not always worth the time and expense. Consider replacement.
