Your energy bills drop because your HVAC system isn’t working overtime to compensate for inefficient windows. Rooms stay comfortable year-round instead of being too hot in summer and freezing in winter.

Quality window installation means your investment actually pays off. Windows that fit right, seal properly, and perform the way they’re supposed to. You get the energy savings, comfort, and peace of mind that comes with knowing the job was done correctly the first time.

What's Included in Professional Window Installation

Complete removal of existing windows and proper disposal. Full installation of new windows with weatherproofing, insulation, and interior/exterior trim work as needed.

We handle the details that matter: proper flashing, adequate insulation around the frame, and making sure everything operates smoothly. Your windows will open, close, and lock properly.

North Stonington homes often need custom solutions due to older construction. We’re equipped to handle non-standard sizes, structural considerations, and the unexpected issues that come up in established homes. You won’t get surprised with extra charges for work that should have been included from the start.

How long does window installation typically take for a whole house?

Most full-house window installations take 1-3 days depending on the number of windows and any complications we encounter. We can usually do 8-12 windows per day if everything goes smoothly. Older homes sometimes present challenges like non-standard sizes or structural issues that can add time, but we’ll let you know upfront if we see potential delays. We don’t rush the job just to meet an arbitrary timeline – proper installation is more important than speed.

What's the difference between cheap windows and quality windows?

Quality windows use better materials, stronger frames, and superior glass technology. Cheap windows often have thin frames that warp, seals that fail quickly, and glass that doesn’t provide real energy efficiency. You’ll replace cheap windows sooner and deal with more problems like drafts, condensation, and operation issues. Quality windows cost more upfront but last 20+ years with minimal maintenance. The energy savings alone usually justify the difference in price within a few years.

Do I need permits for window replacement in North Stonington?

Most window replacements don’t require permits 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 make sure all work meets local building codes. It’s always better to check with the town beforehand rather than deal with issues later when you try to sell your home.

How much money will new windows actually save on energy bills?

Energy savings depend on what you’re replacing and what you install. Homeowners typically see 10-25% reductions in heating and cooling costs with quality replacement windows. If your current windows are single-pane or have failed seals, savings can be even higher. Connecticut’s energy costs make efficiency improvements more valuable than in other areas. We can give you realistic expectations based on your specific situation rather than throwing around inflated savings numbers.

What happens if there's damage to my home during installation?

We carry full liability insurance specifically for this reason. Accidents are rare when you work with experienced installers, but we’re covered if something goes wrong. We also take precautions like protecting floors and furniture, using proper removal techniques, and having the right tools for the job. If we damage something, we fix it or pay to have it fixed properly. This is why working with licensed, insured contractors matters more than saving a few dollars with unlicensed installers.

Can you install windows in winter or do I have to wait?

We install windows year-round in Connecticut. Winter installations require more preparation to keep your home comfortable during the process, but it’s definitely doable. We work efficiently to minimize the time windows are out, and we can often do interior work first to reduce exposure time. Many homeowners actually prefer winter installation because they immediately feel the improvement in comfort and energy efficiency. We just schedule around severe weather and plan the work to minimize disruption to your home’s heating.
