How Installing Energy-Efficient Windows in Milford Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Decrease your carbon footprint: In Milford, you can lower your indirect greenhouse gas emissions by about 147 pounds per year when you upgrade to energy-efficient windows.
- Save on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Milford
Each window installation company provides various services and has varying costs based on a few factors.
How Much Do New Windows Cost?
Typically, Milford homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. This is due to the fact that window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.
It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that switching out the windows on your Milford home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer 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?
The first question to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in Milford
In our search to find the most reliable, eco-friendly window installers in Milford, the EcoWatch team evaluated dozens of companies before settling on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Milford, we only included companies that serve the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Milford.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you get. 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 online reviews to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, cost, professionalism, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

You should use a window installation company whenever you want to upgrade your windows. Installing windows is a involved process that can be difficult to do on your own, so it’s best handled by the professionals.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
