How Installing Energy-Efficient Windows in Clayton Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Clayton
Let's take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
On average, Clayton homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. Costs will vary considerably based on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.
It's also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Clayton home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from multiple window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are usually recommended 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 total window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window without replacing the 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 trying to decide which kind of installation to get, you can consult with your installer and get their advice. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Clayton
EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer 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 a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to ensure its contractors 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 the majority of customers don't have good feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

What is the typical cost to replace windows?
The average cost of installing a window can range between $450 and $650. There are many factors that affect the cost, which include the materials used in designing the windows, styles and sizes of windows, your property's location, the number of windows, how energy-efficient the windows are and local labor costs.
What are the most common types of replacement windows?
