How Installing Energy-Efficient Windows in Simsbury Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Save on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Reduce your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Simsbury
Let’s go over the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which have a higher price tag.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Simsbury homeowners $446+ a year after replacing single-pane windows.
We recommend requesting free quotes from multiple window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In regard to window installations, there are typically two types that your provider will offer: full-frame and pocket installations.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations are simpler and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
Your window installation company will be able to advise you on the best type for your project. In Simsbury, the choice will mostly depend on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Simsbury
EcoWatch differs from most reviewers because we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Simsbury and assigned rankings using the following methodology:
Service Area
Because this is a guide for Simsbury, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Simsbury.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the highest quality service. On the other hand, 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 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
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Simsbury, CT Window Replacement FAQs
How much does a window install cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally dependent on the size of the window, the type and material of the window and the location of your property. Also, remember 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 types of windows?
There are several different kinds of windows you can get for your home, such as bay windows, picture windows, casement windows, slider windows, awning windows, transom windows and double-hung and single-hung windows.
What services do window installation companies offer?
Window installers visit your house to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
How long does window installation generally take?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that have to be installed.
