Complete Window Installation Services

Everything Included, Nothing Extra

Your window installation includes removal and disposal of old windows, proper insulation and sealing, interior and exterior trim work, and complete cleanup.

We handle the permit process if required and coordinate timing around your schedule. Most installations finish in one day, so you’re not dealing with open windows overnight.

Living near the base means understanding military schedules and deployment timelines. We work with families who need flexibility and reliability, whether you’re PCSing next year or staying put long-term.

How long does window installation take for a typical home?

Most homes get completed in one day, depending on the number of windows. A typical house with 10-15 windows usually takes 6-8 hours from start to finish. Larger homes or custom windows might need two days, but we’ll never leave you with open windows overnight. We plan the work so your home stays secure and weather-tight throughout the process.

What type of windows work best in Connecticut's climate?

Double-hung vinyl windows with low-E glass perform best here. They handle temperature swings without warping, the low-E coating cuts energy costs, and quality vinyl won’t rot or need painting. For coastal areas like ours, you want windows rated for high winds and driving rain. We recommend specific brands based on your home’s exposure and your budget.

How much can new windows actually save on energy bills?

Most homeowners see 15-25% reductions in heating and cooling costs after replacing single-pane or old double-pane windows. The exact savings depend on your current windows, home size, and energy usage. Homes with really old windows sometimes save even more. The key is proper installation – even great windows won’t save money if they’re not sealed correctly.

Do you handle permits and inspections for window replacement?

Yes, we handle all permit requirements. Most window replacements don’t need permits if we’re keeping the same size openings, but we check local requirements for every job. When permits are needed, we pull them and coordinate inspections. You don’t have to deal with town offices or worry about code compliance – that’s our responsibility.

What happens if there's damage when you remove old windows?

We inspect the window openings before starting and let you know if we find any issues. Sometimes old windows hide water damage or structural problems that need addressing. We’re equipped to handle common repairs like replacing trim boards or fixing minor framing issues. Major structural work gets discussed and approved before we proceed, so there are no surprise costs.

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

If you’re taping plastic over windows, fighting to open or close them, or seeing condensation between glass panes, replacement usually makes more sense than repairs. Single-pane windows should almost always be replaced for energy efficiency. Windows over 20 years old typically cost more to repair than they’re worth. We’ll give you an honest assessment of whether repair or replacement serves you better.
