How Installing Energy-Efficient Windows in Stratford Saves You Money

There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Stratford

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

How Much Do New Windows Cost?

Typically, 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 significantly based on your location, the current condition of your home, the number of windows you need and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra 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 are the different kinds of windows?

The most common types of windows for homes are awning windows, slider windows, picture windows, casement windows, double-hung and single-hung windows, transom windows and bay windows.

What do window installation companies do?

Window installers visit your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, the weather should be dry, since rain can make the installation more difficult.

When is it time to replace your windows?

Windows typically last around 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to see if they are in need of a repair or replacement.
