How Installing Energy-Efficient Windows in Delaware Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Save on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $328 annually on your energy bills in Delaware.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Decrease your carbon footprint: In Delaware, you can cut your indirect greenhouse gas emissions by about 286 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Delaware

Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

Generally, Delaware homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost you is based on several factors, like size, number of windows, the location of your home, material, type and more.

It's also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your Delaware home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are completely 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?

There are generally two types of window installation services: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has a lot of rot. With this service, your installers will replace the total window, including the frame, trim and sill. Pocket installations are simpler and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

If you're still debating which kind of installation you need, you can ask your provider and get their recommendation. 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 Delaware

In our search to find the most reliable, eco-friendly window installers in Delaware, the EcoWatch team examined dozens of companies before settling on these. We've evaluated the top window installers in Delaware mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Delaware, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Delaware.

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer featured on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, professionalism, quality of installation, cost, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the highest quality service. On the other hand, 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 significant investment, so you'll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Delaware's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Delaware window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Delaware, PA Window Replacement FAQs

How much does a window install cost?

The average cost to install a window can range from $450 to $650. There are several factors that influence the price, such as local labor costs, the number of windows, styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows and your property's location.

What are the different types of windows?

There are several different types of windows you can get for your home, such as slider windows, picture windows, double-hung and single-hung windows, transom windows, awning windows, bay windows and casement windows.

Can you install your own windows?

Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

How often do you need to replace 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 any damage on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all your windows at the same time is the only way to gain that benefit. However, if you have only a few windows that are damaged or leaky, you can replace just those.
