How Installing Energy-Efficient Windows in Stratford Saves You Money

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

  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
  • Better temperature control in your home: Living in a very cold place like Stratford can often mean needing your heater to keep your home cool. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Stratford

Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the average costs and the primary services that you'll find from window installers.

How Much Do New Windows Cost?

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

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

Getting free quotes from several installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the full window, including the sill, frame and trim. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Stratford

EcoWatch differs from other reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:

Service Area

Since this is a guide for Stratford, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Stratford.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company included in our guide to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, warranty, cost and more.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is well protected. 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 installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Stratford, CT Window Replacement FAQs

How much does window installation cost?

The national average cost of installing a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What type of window is the best for energy efficiency?

A window's energy efficiency is affected by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Can you install your own windows?

Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

How long does window installation generally take?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.
