What You Get With Proper Installation

Your energy bills drop. That’s usually the first thing homeowners notice after we install their new windows.

But the real difference shows up in January when your house stays warm without cranking the heat. No more cold spots near windows. No more fighting with the thermostat because one room won’t heat up.

Your home becomes quieter too. Traffic noise, lawn mowers, barking dogs – all muffled by windows that actually seal properly. And if you’re thinking about selling eventually, quality windows add real value that buyers notice immediately.

Lebanon Window Installation Company

We Know Connecticut Windows

Sullivan Contracting has been installing windows in Lebanon and eastern Connecticut for years. We understand how New England weather beats up windows and what it takes to install them right.

Most window problems come down to installation, not the window itself. A great window installed poorly will leak, draft, and fail early. We measure twice, install once, and make sure everything seals properly before we leave.

Window Installation Process Lebanon

How We Install Your Windows

We start with accurate measurements at your home. Every window opening is different, even in the same house, so we measure each one individually.

Once your windows arrive, we remove the old windows carefully to avoid damaging your siding or interior trim. The new window goes in with proper flashing and sealing – this step matters more than most people realize because it prevents water damage and air leaks.

We insulate around the frame, adjust everything so it opens and closes smoothly, then clean up completely. You’ll know immediately if the installation is right because the window will operate easily and you won’t feel any air movement around the edges.

What's Included With Every Installation

Every window installation includes proper flashing, insulation, and weatherproofing. We don’t cut corners on the details that prevent problems later.

You get windows sized exactly for your openings, not generic sizes that kind of fit. We handle any necessary permits and make sure everything meets Connecticut building codes. Most Lebanon homes were built when energy codes were different, so we bring everything up to current standards.

The installation includes cleanup and disposal of your old windows. We also adjust and test every window to make sure it opens, closes, and locks properly before we consider the job finished.

How long does window installation take in Lebanon, CT?

Most window installations take one to two days depending on how many windows you’re replacing. Single-story homes with standard-sized windows usually finish in one day. Two-story homes or houses with custom-sized windows might take two days. We work efficiently but don’t rush the sealing and insulation steps because those determine how well your windows perform long-term. Weather can affect timing since we need dry conditions for proper installation.

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

Spring through fall works best for window installation in Connecticut. We can install windows in winter, but it’s harder on everyone when it’s 20 degrees outside and we’re opening up your house. Late spring and early fall are ideal because the weather is mild and you have time to enjoy the energy savings before the next heating season. Summer works fine too, though you’ll want to plan around any vacation schedules since we’ll need access to your home.

Do I need permits for window replacement in Lebanon?

Most window replacements in Lebanon 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 work, you’ll need permits. We handle permit applications when they’re required and make sure all work meets Connecticut building codes. It’s always better to check with the town first rather than assume, especially for older homes where previous work might not have been permitted.

How much do new windows cost in Lebanon, CT?

Window replacement costs vary based on window size, style, and quality level. Most homeowners in Lebanon spend between $400-800 per window including installation. Larger windows, custom sizes, or premium features like triple-pane glass cost more. The total project cost depends on how many windows you’re replacing and whether any repairs are needed to the window openings. We provide detailed written estimates so you know exactly what you’re paying for before work begins.

What window brands do you install in Lebanon?

We install several quality window brands that perform well in Connecticut’s climate. The specific brand matters less than proper installation and choosing windows rated for our weather conditions. We typically recommend vinyl or fiberglass windows for most Lebanon homes because they handle temperature changes well and require minimal maintenance. We’ll discuss different options during your estimate and explain the pros and cons of each based on your specific situation and budget.

Will new windows really lower my energy bills?

Yes, if your current windows are old or poorly installed. Most homeowners see 15-25% reductions in heating and cooling costs after replacing single-pane or failing double-pane windows. The savings depend on what you’re replacing and how much you currently spend on energy. Homes with very old windows or windows that visibly leak air see the biggest improvements. New windows also make your heating and cooling system work less, which can extend its life and reduce repair costs.
