How Installing Energy-Efficient Windows in Clayton Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save more on your bills.
- Better temperature control in your home: Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Clayton
Let's go over the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
Even though the typical of installing a single window is around $600, it can range from $200 to $1,200. These estimates vary based on specific characteristics of your installation, such as material, size, the location of your home, number of windows, type and more.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts 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 depending on your local climate, energy rates and individual home characteristics.
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 if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Because full-frame installations are more involved, they will raise the overall cost. A pocket installation entails replacing a window without taking out the entire frame, which is generally cheaper than a full-frame installation.
Your window installation company will be able to recommend the best type for your project. In Clayton, the choice will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Clayton
In our hunt to make your home improvements easier and more eco-friendly in Clayton, the EcoWatch team evaluated dozens of companies before deciding on these. We've assessed the top window installers in Clayton mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Clayton so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you opt for. 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
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have nice things to say about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Clayton's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Clayton window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Clayton, DE Window Replacement FAQs
How much should a window install cost?
The typical cost of replacing a single window can range between $450 and $650. There are many factors that influence the price, including the number of windows, local labor costs, the materials used in designing the windows, how energy-efficient the windows are, your property's location and styles and sizes of windows.
What are the kinds of windows?
There are various kinds of windows you can get for your house, such as picture windows, bay windows, awning windows, transom windows, double-hung and single-hung windows, slider windows and casement windows.
When should I use a window installation company?
Unless you're handy and have all the tools you need to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
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 should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
