How Installing Energy-Efficient Windows in Simsbury Saves You Money
There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky.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 real estate value.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save $446 a year on your bills.
Estimated Cost of Window Replacement in Simsbury
Windows come in different styles, purposes and shapes, so costs and services will vary remarkably depending on several factors. Below, we detail the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the typical cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, such as type, size, material, the location of your home, number of windows and more.
It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Simsbury homeowners $446+ a year when replacing single-pane windows.
Another factor that affects the overall cost is the material you pick for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your professionals will replace the full window, including the sill, frame and trim. A pocket installation involves installing a new window without replacing the frame. So, instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which kind of installation to get, you can consult with your installer and get their advice. The decision mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Simsbury
EcoWatch differs from other reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Simsbury, we only included companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Simsbury.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks 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 find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, cost, professionalism, quality of installation, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try 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. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Simsbury's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Simsbury window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Simsbury, CT Window Replacement FAQs
How much should a window install cost?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
The most common types of windows for homes include: slider windows, picture windows, transom windows, awning windows, bay windows, casement windows and double-hung and single-hung windows.
Can I replace my own windows?
If you're handy and have experience with installing a replacement window, you may be able to install your own windows. But if you don't have the time or skills, we don't recommend trying it.
What time of year is the best time to replace my windows?
Even though you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, the weather should be dry, because rain can make the installation more difficult.
Should I replace all my windows at once?
If you're upgrading your windows to get more efficient windows, replacing all of your windows at the same time is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
