20 Best Window Companies in Windsor, CT (2025 Reviews)

How Installing Energy-Efficient Windows in Windsor Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, such as:

• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Save on energy bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $446 annually on your energy bills in Windsor.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Windsor

Each window replacement company offers varying services and has different price points based on a few factors.

How Much Do New Windows Cost?

On average, homeowners in Windsor can expect that most window installations will range from $250 to $1,200, with the average cost at about $600. Costs will vary considerably based on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Windsor homeowners $446+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first step when considering a window replacement is to clarify whether you need a full-frame or pocket installation.

Full-frame installations are usually recommended when you want a new style or your window has significant deterioration. With this service, your professionals will replace the complete window, including the frame, sill and trim. Pocket installations are simpler and won’t carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

Your window installer should be able to help you figure out which type of installation you should get.
