How Installing Energy-Efficient Windows in Old Saybrook Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- 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.
- Save on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 147 pounds.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Old Saybrook
Windows come in varying shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
Even though the typical of replacing one window is about $600, it can range from $200 to $1,200. But costs will vary considerably depending on the quality of your products, the number of windows you need, the current condition of your home and your location. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $403 a year on your energy bills in Old Saybrook.
Getting free quotes from several providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're not sure which window installation service you need, your installer can advise you. Typically, 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 Old Saybrook
EcoWatch reviews are different from other reviews, as we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:
Service Area
Since this is a guide for Old Saybrook, we gave more points to companies that provide services to the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Old Saybrook.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice feedback about their service from a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Old Saybrook's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Old Saybrook window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Old Saybrook, CT Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally influenced by the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies offer?
Window installers cover the entire process — from replacing your old windows with new ones to cleaning up after the installation. In addition, many companies offer window manufacturing, customization and repairs.
How long does it generally take to install windows?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.
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 make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
