How Installing Energy-Efficient Windows in Oak Ridge Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Oak Ridge
Windows come in various styles, shapes and purposes, so costs and services will vary greatly depending on several factors. Below, we describe the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
Typically, Oak Ridge homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at around $600. But costs will differ significantly based on the number of windows you need, your location, the current condition of your home and the quality of your products. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.
With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oak Ridge homeowners $345+ each year after replacing single-pane windows.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its 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 still debating which kind of installation you should get, you can ask your provider and get their recommendation. The choice mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Oak Ridge
EcoWatch reviews differ from most reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Oak Ridge and assigned rankings based on the following methodology:
Service Area
This one is pretty 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 best window installation company near you.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the most quality service. Still, we want to make sure we're highlighting companies that provide 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 give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Oak Ridge, NC Window Replacement FAQs
How much does a window install cost?
The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
There are several different types of windows you can get for your home, such as awning windows, casement windows, picture windows, slider windows, bay windows, double-hung and single-hung windows and transom windows.
When do I need to use a window installation company?
You should hire a window installation professional whenever you need new windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best handled by the professionals.
How often should you replace your windows?
Windows usually have a lifespan of about 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 see if they need any repairs or replacements.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are broken or drafty, you can replace just those.
