How Installing Energy-Efficient Windows in Stratford Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, including:

  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
  • Save on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in Stratford

Windows come in different shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you’ll find from window installers.

How Much Do New Windows Cost?

Even though the average cost of installing one window is around $600, it can range anywhere from $200 to $1,200. This is because the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $441 a year on your energy bills in Stratford.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

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

A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which type of installation you should get, you can talk to your provider and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Stratford

EcoWatch is different from other reviewers since we’re examining these companies through a sustainability lens. We’ve evaluated the top window installers in Stratford mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Stratford, we only included companies that cover the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Stratford.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have nice feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.

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 awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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

Stratford, CT Window Replacement FAQs

How much does window installation cost?

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

What type of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies do?

Window installation professionals will do the entire process — from replacing old windows with new ones to cleaning up after the installation. In addition, a lot of companies offer window manufacturing, customization and repairs.

How often should you replace windows?

Windows typically have a lifespan of 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 determine if they are in need of a repair or replacement.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, it’s probably time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
