How Installing Energy-Efficient Windows in Middletown Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on power bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save around $403 annually on your energy bills in Middletown.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 147 pounds.
Estimated Cost of Window Replacement in Middletown
Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
Generally, Middletown homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.
It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Middletown homeowners $403+ a year when replacing single-pane windows.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In general, there are two types of window installation services you can get: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window replacement company will be able to help you decide what's best for your needs. In Middletown, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Middletown
In our search to find the most reliable, eco-friendly window installers in Middletown, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We have reviewed the top window installation companies in Middletown mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your energy 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 Middletown, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Middletown.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies 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 sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Middletown, CT Window Replacement FAQs
How much should a window install cost?
The national average cost to install a window is around $600 but can range from $200 to $1,200, based on several factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
The most common kinds of windows for homes are transom windows, double-hung and single-hung windows, casement windows, picture windows, bay windows, awning windows and slider windows.
Can I replace my own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of 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. What's most important is that the weather should be dry.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
