What's Included in Every Installation

Every window installation includes proper weatherproofing, interior and exterior trim work, and complete cleanup. We handle permits when required and make sure everything meets local building codes.

You get windows designed for New England weather, not generic products that might work somewhere else. We source materials that handle temperature swings, humidity, and salt air exposure that comes with living near the coast.

The installation includes proper insulation around each window frame, quality caulking that lasts, and attention to details that prevent air leaks. Your windows will perform the way they’re supposed to from day one.

How long does window installation typically take in East Lyme?

Most residential window installations take one to two days, depending on how many windows you’re replacing and the complexity of the job. Single-story homes with standard-sized windows usually wrap up in a day. Two-story homes or custom window sizes might need an extra day. We’ll give you an accurate timeline during the initial consultation based on your specific project. Weather can sometimes affect scheduling, especially during Connecticut’s winter months, but we plan around seasonal conditions to minimize delays.

What type of windows work best for coastal Connecticut weather?

Vinyl and fiberglass windows perform exceptionally well in East Lyme’s coastal climate. They resist salt air corrosion, handle humidity without warping, and provide excellent insulation against temperature extremes. Double or triple-pane glass with low-E coatings helps with energy efficiency during hot summers and cold winters. Wood windows can work but require more maintenance due to moisture exposure. We’ll recommend specific window types based on your home’s exposure to coastal conditions and your energy efficiency goals.

Do I need permits for window replacement in East Lyme?

Most standard window replacements don’t require permits in East Lyme if you’re replacing existing windows with similar sizes. However, if you’re changing window sizes, adding new windows, or doing structural modifications, permits are typically required. We handle permit applications when needed and ensure all work meets local building codes. It’s always better to check with the town beforehand, and we can guide you through the requirements during our consultation.

How much can new windows actually save on energy bills?

Homeowners in Connecticut typically see 10-25% reductions in heating and cooling costs after replacing old, drafty windows with energy-efficient models. The exact savings depend on your current windows’ condition, your home’s overall insulation, and the efficiency rating of your new windows. Homes with single-pane windows or windows over 15 years old usually see the biggest improvements. With Connecticut’s energy costs, these savings add up significantly over time, often paying for a portion of the window investment within a few years.

What happens if there's damage to the wall during installation?

Professional window installation rarely causes wall damage when done correctly, but we’re prepared for any issues that arise. Sometimes we discover rot or structural problems around old windows that weren’t visible beforehand. We’ll discuss any findings with you immediately and provide options for repairs. We handle minor trim work and touch-ups as part of the installation. For larger structural issues, we’ll give you a clear explanation of what’s needed and fair pricing for additional work.

How do I know if my windows need replacement or just repair?

If you’re feeling drafts, seeing condensation between glass panes, or struggling to open and close windows, replacement is usually the better investment. Windows over 15-20 years old, especially single-pane models, typically cost more to heat and cool than they’re worth keeping. Visible rot, warping, or gaps around the frame are clear signs it’s time for new windows. We can assess your current windows and give you an honest evaluation of whether repair or replacement makes more financial sense for your situation.
