How Installing Energy-Efficient Windows in Graham Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, such as:
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- 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- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky.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.
Estimated Cost of Window Replacement in Graham
Windows come in different shapes and sizes, so costs and services will vary considerably. Here are the average costs and the primary services that you’ll find from window installers.
How Much Do New Windows Cost?
Typically, homeowners in Graham can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. Costs will vary considerably depending on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
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 $350 a year on your energy bills in Graham.
Costs will also vary based on the material you want for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most 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 installations, there are typically two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations involve replacing the total 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. Because these installations are more involved, they will increase the overall cost. A pocket installation entails replacing a window within the existing frame. This means instead of taking out the whole unit and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Graham
EcoWatch is different from most reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Graham and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Graham area so you can find a quality 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 company included in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, warranty, quality of installation, cost, quality of parts and more.
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 the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Graham’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Graham window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Graham, NC Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to install one window is about $600 but can range between $200 and $1,200, based on several factors. The price is usually dependent on 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 upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
There are several different kinds of windows you can get for your home, including transom windows, picture windows, bay windows, double-hung and single-hung windows, awning windows, casement windows and slider windows.
What do window installation companies do?
Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
How long does window installation generally take?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
