How Installing Energy-Efficient Windows in Town and Country Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Save on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $376 annually on your energy bills in Town and Country.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Town and Country
When researching window installation, each company provides varying services and costs. Let’s look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. Costs will differ significantly based on the quality of your products, your location, the number of windows you need and the current condition of your home. Many window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Asking for free quotes from several installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot or deterioration. These installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re not sure which type of window installation service you should get, your installer can help you out. In general, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Town and Country
The EcoWatch Reviews team differs from most reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Town and Country and assigned rankings using the following methodology:
Service Area
Because this is a guide for Town and Country, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Town and Country.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have good feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Town and Country’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Town and Country window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window.

The most common kinds of windows for homes are double-hung and single-hung windows, awning windows, transom windows, casement windows, slider windows, bay windows and picture windows.
Can I replace my own windows?
If you’re handy and know how to replace a window, it’s possible to install your own windows. But if you don’t have the time or skills, we don’t recommend doing it on your own.
How do you know it’s time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.

Since a window takes about 30 minutes to install, about 16 windows can be installed during a typical 8-hour work day.
