Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. If your windows are drafty or damaged, you could be losing 25-30% of your house's heat or cool air right out of them.
Installing efficient windows on your property can help you save money each month on your power bills — and you can help the environment, too.
Efficient windows are of particular importance in Griswold, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $424 a year.

How Installing Energy-Efficient Windows in Griswold Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to consider making the switch:
- Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
- 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 fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Griswold
Let's take a look at the cost of window installation and the kinds of services offered by installers.
How Much Do New Windows Cost?
Though the typical of replacing one window is around $600, it can range from $200 to $1,200. This is because window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Griswold home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, though 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?
When it comes to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you understand what's best for your needs. In Griswold, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Griswold
EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Griswold and ranked them using the following methodology:
Service Area
Since this is a guide for Griswold, we only included companies that serve 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 Griswold.
Work Quality
When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. 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 customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, quality of parts, quality of installation, professionalism, warranty and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Griswold's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Griswold window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Griswold, CT Window Replacement FAQs
How much should a window install cost?
The typical cost to replace one window ranges from $450 to $650. There are several factors that affect the price, which include your property's location, styles and sizes of windows, the number of windows, local labor costs, the materials used in designing the windows and how energy-efficient the windows are.
What are the most common types of replacement windows?
The most common kinds of windows for homes are slider windows, double-hung and single-hung windows, picture windows, casement windows, bay windows, transom windows and awning windows.
Do you really have to use a window installation company?
Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.
How long does it usually take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed in a typical 8-hour work day.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
