Why you can trust EcoWatch
Although green 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 big impact on home energy conservation. According to the Department of Energy, heat or cool air lost through outdated, drafty windows could make up 25-30% of household energy climate control costs.
Installing efficient windows on your property can help you save money every month on your power bills — and you can help the environment as well.
Efficient windows are of particular importance in Mystic, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $424 per year.

How Installing Energy-Efficient Windows in Mystic Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, such as:
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 147 pounds.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Mystic
Each window installation company offers varying services and has varying price points based on a few factors.
How Much Do New Windows Cost?
According to our research, the typical cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But prices differ remarkably 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 installations, which will add extra costs to your project.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $424 a year on your energy bills in Mystic.
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 light, but they provide 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 as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two types of window installation services you can get: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has significant deterioration. With this service, your professionals will replace the whole window, including the frame, trim and sill. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.
Your window replacement company will be able to help you understand what's best for your needs. In Mystic, the decision will mostly be based on the age of your home and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Mystic
In our hunt to make your home improvements easier and more eco-friendly in Mystic, EcoWatch evaluated many companies before landing on these. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Mystic, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Mystic.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, quality of parts, professionalism, cost, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you'll want to make sure that investment is protected. Window installation companies that offer 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 a proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Mystic, CT Window Replacement FAQs
How much does window installation cost?
The average cost to install one window ranges from $450 to $650. There are many factors that affect how much it costs, which include the number of windows, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, local labor costs and your property's location.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
Although you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
When is it time to replace your windows?
Windows generally have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on your energy bills, replacing all of your windows together is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
