How Installing Energy-Efficient Windows in Elizabethton Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Elizabethton, that’s about 528 pounds per year on average.
Estimated Cost of Window Replacement in Elizabethton
Each window installation company offers varying services and has different costs depending on several factors.
How Much Do New Windows Cost?
Typically, Elizabethton homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. These numbers are based on specific characteristics of your installation, such as type, material, the location of your home, size, number of windows and more.
Whether or not you want to install 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 $294 a year on your energy bills in Elizabethton.
We advise requesting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window within the old frame. This means instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company will be able to help you figure out what’s best for your needs. In Elizabethton, the decision will mostly be based on the age of your home and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Elizabethton
EcoWatch reviews differ from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
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 in our guide to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have nice things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Elizabethton’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Elizabethton window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Elizabethton, TN Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
A window’s energy efficiency is influenced by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installation professionals visit your house to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.
How do you know it’s time to replace your windows?
Windows usually have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have them checked by an expert to determine if they need any repairs or replacements.
