How Installing Energy-Efficient Windows in East Granby Saves You Money
When you switch to energy-efficient windows, you may see several perks, including:
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Installing energy-efficient windows can help lower that amount, which helps you save more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in East Granby
Each window installation company provides varying services and has different costs depending on a few factors.
How Much Do New Windows Cost?
Though the national average of installing a single window is about $600, it can range from $200 to $1,200. How much it will cost you depends on several factors, such as material, the location of your home, number of windows, type, size and more.
It's also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your East Granby home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end 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, you should opt for a full-frame installation instead.
If you're unsure which kind of window installation service you need, your installer should be able to help you out. Generally, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in East Granby
In our search to make your home improvements easier and more eco-friendly in East Granby, the EcoWatch team assessed many companies before settling on these. We have evaluated the top window replacement companies in East Granby 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 cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for East Granby, we paid more attention 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 East Granby.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies with 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 installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
East Granby, CT Window Replacement FAQs
What is the average cost to install windows in a home?
The typical cost of replacing one window ranges from $450 to $650. There are a variety of factors that influence the price, such as the number of windows, styles and sizes of windows, your property's location, how energy-efficient the windows are, the materials used in designing the windows and local labor costs.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes include: casement windows, awning windows, slider windows, bay windows, picture windows, double-hung and single-hung windows and transom windows.
Can you replace your own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
How long does window installation take?
Each window takes around 30 minutes to install depending 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 need to be installed.
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 often better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
