How Installing Energy-Efficient Windows in Tolland Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, including:
- Save money on electricity bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $461 annually on your energy bills in Tolland.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- 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 your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Tolland
Windows come in varying shapes, styles and purposes, so costs and services will differ considerably depending on several factors. Below, we go over the typical cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. But costs differ remarkably 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 offer door installations and replacements, which carry a higher price tag.
It’s also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your Tolland home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that affects the overall cost is the material you select for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as 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?
When it comes to window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the 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 installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Tolland
In our hunt to make your home improvements easier and more eco-friendly in Tolland, EcoWatch evaluated many companies before landing on these. We’ve evaluated the top window installation companies in Tolland mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Tolland area so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of installation, professionalism, quality of parts, cost and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to be certain 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
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Tolland, CT Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost to replace a single window can range from $450 to $650. There are many factors that affect how much it costs, which include the number of windows, local labor costs, styles and sizes of windows, your property’s location, how energy-efficient the windows are and the materials used in designing the windows.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are awning windows, picture windows, casement windows, double-hung and single-hung windows, transom windows, bay windows and slider windows.
What do window installation companies do?
Window installation professionals visit your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
What time of year is a good time to replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
