How Installing Energy-Efficient Windows in East Haddam 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 are the following:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your home.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in East Haddam
Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the average costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
The average cost to replace a single window is about $600 but can range from $200 to $1,200. How much it will cost varies depending on several factors, like number of windows, the location of your home, material, size, type and more.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save East Haddam homeowners $403+ per year after replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from 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 provide decent insulation for your home.
What Services do Window Installers Offer?
When considering window replacements, there are typically two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has significant deterioration. With this service, your installers will replace the full window, including the frame, trim and sill. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
Your window replacement company will be able to help you choose what's best for your needs. In East Haddam, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in East Haddam
EcoWatch reviews differ from most reviews, as we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed each installer 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 East Haddam so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window 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
We analyzed patterns in recent customer feedback to find the companies with the most 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, quality of parts, warranty, cost, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, 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 to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
East Haddam, CT Window Replacement FAQs
What is the average cost to install windows in a home?
The average cost of installing one window ranges from $450 to $650. There are several factors that influence how much it costs, which include the number of windows, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, your property's location and local labor costs.
Which type of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are 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 attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installation companies will do the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. In addition, some companies offer window manufacturing, customization and repairs.
How often do you need to replace windows?
Windows typically have a lifespan of about 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.
Should I replace my windows all at once?
If you're upgrading your windows to get more efficient windows, replacing all of your windows at once is the only way to gain that benefit. However, if you have only one or two windows that are damaged or leaky, you can replace just those.
