How Installing Energy-Efficient Windows in Kensington Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could benefit you:

  • More efficient energy use in your household: In Kensington where the winters can be very cold, energy-efficient windows decrease the amount of heat that is lost through your windows, which makes it easier to keep your house warm.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Kensington, that's about 147 pounds per year on average.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Kensington

Windows come in various styles, shapes and purposes, so costs and services will differ considerably based on your project. Below, we describe the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is because window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

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 decreasing your energy bills. Investing in certified energy-efficient windows can save Kensington homeowners $446+ a year when replacing single-pane windows.

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 maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations are on the simpler end and won't cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Kensington

EcoWatch reviews are different from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Kensington and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Kensington, CT Window Replacement FAQs

How much should a window install cost?

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

What are the most common types of replacement windows?

There are several different types of windows you can get for your home, such as picture windows, bay windows, slider windows, double-hung and single-hung windows, casement windows, awning windows and transom windows.

Do I really have to use a window installation company?

Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.

How often do you need to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
