How Installing Energy-Efficient Windows in Smyrna Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Save on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Better temperature control in your home: Residing in a very cold place like Smyrna can often mean needing your heater to keep your home cool. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Smyrna
Windows come in varying purposes, styles and shapes, so costs and services will differ tremendously based on several factors. Below, we detail the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
According to our market research, the national average cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. Costs will differ significantly depending on the number of windows you need, your location, the quality of your products and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Asking for free quotes from several providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first step when planning a window replacement is to clarify whether you need a full-frame or pocket installation.
A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation involves replacing a window within the frame that's already there. So, instead of tearing out the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to advise you on the best type for your project. In Smyrna, the decision will mostly depend on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Smyrna
In our search to make your home improvements easier and more eco-friendly in Smyrna, the EcoWatch team landed on the above companies as the best window installation companies in the city. We've reviewed the best window installation companies in Smyrna primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Smyrna, we gave more points to companies that cover the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Smyrna.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have good things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a significant investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Smyrna's climate, homeowners need to be wary of rot, low efficiency and water damage. 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 average cost to install new windows?
The average cost of installing one window can range between $450 and $650. There are several factors that affect the price, such as your property's location, the materials used in designing the windows, styles and sizes of windows, the number of windows, how energy-efficient the windows are and local labor costs.
Which type of window should I get?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Do you really need to use a window installation company?
You should use a window installation company whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best left to the professionals.
How long does window installation generally take?
Since the average installation time is 30 minutes per window, around 16 windows can be installed in a typical 8-hour work day.
