How Installing Energy-Efficient Windows in New Canaan Saves You Money

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

  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In New Canaan, that’s about 147 pounds per year on average.

Estimated Cost of Window Replacement in New Canaan

Let’s take a look at the cost of window replacement and the types of services you may need for your home.

How Much Do New Windows Cost?

Typically, New Canaan homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at about $600. But costs will vary considerably depending on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.

Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. So, instead of taking out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which type of installation to get, you can consult with your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in New Canaan

In our hunt to find the most reliable, eco-friendly window installers in New Canaan, the EcoWatch team evaluated dozens of companies before landing on these. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:

Service Area

Because this is a guide for New Canaan, we gave more points to companies that cover the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in New Canaan.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, quality of parts, professionalism, warranty, quality of installation and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of New Canaan’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of New Canaan window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

New Canaan, CT Window Replacement FAQs

What is the average cost to install new windows?

The average cost of installing a window can range from $450 to $650. There are many factors that affect the cost, including how energy-efficient the windows are, local labor costs, the materials used in designing the windows, styles and sizes of windows, the number of windows and your property’s location.

Which kind of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installers go to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.

What time of year is a good time to replace my windows?

Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, it’s most likely time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
