Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home’s energy efficiency can also have a considerable impact on home energy conservation. If your windows are outdated or damaged, you could be sending 25-30% of your house’s heat or cool air right out of them.
Replacement windows improve your home’s insulation, not only making you and your family more comfortable during the summer and winter, but also saving you some money and helping the environment.
Efficient windows are especially important in Sanford, where summers are long and hot. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $355 per year.

How Installing Energy-Efficient Windows in Sanford Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:
- Save money on energy bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $355 annually on your energy bills in Sanford.
- Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- 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: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Sanford
Windows come in various shapes and sizes, so costs and services will differ considerably. Here are the average costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
Generally, homeowners in Sanford can expect that most window installations will cost between $250 and $1,200, with the average cost at about $600. But costs will vary considerably based on the quality of your products, the number of windows you need, your location and the current condition of your home. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.
Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $355 a year on your energy bills in Sanford.
The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Sanford, the decision will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Sanford
EcoWatch reviews differ from other reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Sanford and ranked them based on the following methodology:
Service Area
Since this is a guide for Sanford, we only included 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 Sanford.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have positive feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, 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. That’s why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Sanford, NC Window Replacement FAQs
How much should window installation cost?
The average cost to install a window ranges between $450 and $650. There are a variety of factors that affect the cost, which include the materials used in designing the windows, the number of windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are and your property’s location.
What are the most common types of replacement windows?
There are various kinds of windows you can get for your house, such as picture windows, double-hung and single-hung windows, bay windows, awning windows, transom windows, slider windows and casement windows.
When do I need to use a window installation company?
Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
