How Installing Energy-Efficient Windows in Middlebury Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:
- Save money on energy bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save around $420 annually on your energy bills in Middlebury.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 147 pounds.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Middlebury
Let's go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Typically, homeowners in Middlebury can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will add extra costs to your project.
Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Another factor that influences the overall cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage or rot. Full-frame installations are more involved and will raise overall costs. Pocket installations (or retrofits) entail 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 should opt for a full-frame installation instead.
Your window replacement company should be able to help you decide what's best for your needs. In Middlebury, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Middlebury
EcoWatch reviews differ from other reviews since we're examining these companies through a sustainability lens. We've assessed the top window replacement companies in Middlebury mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Middlebury, we only included companies that provide services to the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Middlebury.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers more points 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 most customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have 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 been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Middlebury, CT Window Replacement FAQs
How much should a window install cost?
The national average cost to replace one window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the types of windows?
There are several different types of windows you can get for your house, including double-hung and single-hung windows, casement windows, awning windows, transom windows, slider windows, bay windows and picture windows.
What do window installers do?
Window installers go to your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How often do you need to replace windows?
Windows usually last around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them looked at by an expert to determine if they need any repairs or replacements.
