Why you can trust EcoWatch
A guide on the top window installation companies in Spencer may not seem like the most compelling article on EcoWatch, but trust us, windows have more of an impact on your life than you might think. The Department of Energy estimates that heat or cool air lost through traditional or outdated windows could be responsible for close to 30% of residential energy climate usage. In Spencer, where the electricity bills are an average of $42 per month, that's almost $$149 per year wasted.
That's not great for either your wallet or the environment, but one of the best window installation companies can help with that.
Efficient windows are particularly important in Spencer, where summers are long and hot. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $347 per year.

How Installing Energy-Efficient Windows in Spencer Saves You Money
Switching 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 benefit you:
- Better temperature control in your home: When you reside in a city like Spencer where the summers can be very hot, you often need to depend on your air conditioner to keep your house cool. Energy-efficient windows can reduce how hard your AC needs to work to cool your home.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Spencer, that's about 345 pounds per year on average.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household 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.
Estimated Cost of Window Replacement in Spencer
Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
According to our market research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. These estimates vary based on the specifics of your installation, like the location of your home, number of windows, type, material, size and more.
Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Requesting free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the full window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end 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 type of installation to get, you can talk to your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Spencer
EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We've assessed the best window installers in Spencer primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Spencer, we only included companies that cover the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Spencer.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, quality of parts, warranty, cost, professionalism and more.
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 provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a hefty investment, so you'll want to be certain 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 Spencer's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Spencer window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Spencer, NC Window Replacement FAQs
What is the typical cost to install windows?
The average cost to install one window ranges between $450 and $650. There are many factors that affect the price, which include the number of windows, styles and sizes of windows, the materials used in designing the windows, local labor costs, how energy-efficient the windows are and your property's location.
Which type of window should I get?
A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installers visit your home to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How often do you need to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace all my windows at once?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
