Complete Window Installation, Done Right

Every window installation includes proper removal of old windows, professional installation with weatherproofing, interior and exterior trim work, and complete cleanup. We handle all the details so you don’t have to.

We work with quality window manufacturers that offer energy-efficient options suitable for Connecticut’s climate. Whether you need double-hung, casement, or specialty windows, we’ll help you choose the right style and features for your home and budget.

Our installations include proper insulation, flashing, and sealing to prevent air leaks and water infiltration. This attention to detail is especially important in coastal areas like Niantic where weather exposure is more intense.

How long does window installation typically take?

Most window installations are completed in one to two days, depending on the number of windows and any complications we encounter. A typical home with 10-12 windows usually takes a full day. We’ll give you a realistic timeline during your consultation and stick to it. We work efficiently but never rush the important details like proper sealing and weatherproofing that ensure your windows perform well for years.

What's the best time of year for window installation?

Window installation can be done year-round in Connecticut, but spring through fall offers the most comfortable conditions. We avoid installation during severe weather, but moderate temperatures actually make the work easier and more comfortable for everyone. If you’re dealing with drafty windows, don’t wait – the energy savings start immediately after installation, and delaying just means higher heating bills through winter.

How do I know if I need full window replacement?

If your windows are drafty, difficult to open or close, show condensation between glass panes, or are more than 20 years old, replacement usually makes more sense than repairs. Single-pane windows or windows with rotting frames definitely need replacement. During our consultation, we’ll assess your current windows honestly and let you know if some can be repaired or if replacement is the better investment.

What type of windows work best in coastal Connecticut?

Vinyl or fiberglass windows perform exceptionally well in coastal areas like Niantic because they resist salt air corrosion and don’t require regular maintenance like wood. Double or triple-pane glass with low-E coatings help with energy efficiency. We recommend windows specifically rated for coastal exposure and high wind loads. The investment in quality materials pays off in longevity and performance in our challenging climate.

Do you handle permits for window replacement?

Most standard window replacements in existing openings don’t require permits in Connecticut, but we’ll verify this based on your specific project and local requirements. If permits are needed, we can guide you through the process or handle it directly. We’re familiar with local building codes and ensure all installations meet or exceed requirements, whether permits are required or not.

What warranty comes with your window installation?

You get two warranties – one from the window manufacturer covering the windows themselves, and our installation warranty covering our workmanship. Manufacturer warranties typically range from 10 years to lifetime depending on the brand and model you choose. Our installation warranty covers any issues related to our work, including leaks or installation defects. We stand behind both the products we install and the quality of our installation work.
