How Installing Energy-Efficient Windows in Smyrna Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy once 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 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $281 a year on your bills.
Estimated Cost of Window Replacement in Smyrna
Windows come in different shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you can find from window installers.
How Much Do New Windows Cost?
According to our market research, the national average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will make your project cost more.
It’s important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Smyrna homeowners $281+ a year when replacing single-pane windows.
We advise requesting free quotes from several window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
When considering window replacements, in general there are two kinds that your installer will offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re not sure which window installation service you should get, your installer can assist you. Typically, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Smyrna
In our search to find the most reliable, eco-friendly window installers in Smyrna, the EcoWatch team assessed dozens of companies before deciding on these. We’ve decided to assess the best window installation companies in Smyrna mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Smyrna, we only included companies that cover the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Smyrna.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, cost, warranty, quality of installation, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window installers won’t always provide the most quality service. On the other hand, we want to make sure 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 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 Smyrna’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Smyrna window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Smyrna, DE Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of replacing a window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
The most common kinds of windows for homes are casement windows, awning windows, picture windows, bay windows, transom windows, slider windows and double-hung and single-hung windows.
Can I replace my own windows?
If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don’t have the time or experience, we recommend getting a professional to do it for you.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, it shouldn’t be raining, because rain can make the installation more difficult.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
