How Installing Energy-Efficient Windows in Walker Mill Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, such as:
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Walker Mill, that's about 249 pounds per year on average.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Walker Mill
Windows come in different shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
On average, Walker Mill homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. Costs will vary significantly depending on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
Bear in mind that energy-efficient windows may cost more, 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. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without removing the whole frame, which is usually cheaper than a full-frame installation.
Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Walker Mill
In our search to find the most reliable, eco-friendly window installers in Walker Mill, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:
Service Area
Since this is a guide for Walker Mill, we only included companies that serve the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Walker Mill.
Work Quality
When picking 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 rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, cost, warranty, quality of installation, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Walker Mill, MD Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost to replace a single window ranges between $450 and $650. There are a variety of factors that influence how much it costs, which include the materials used in designing the windows, how energy-efficient the windows are, your property's location, the number of windows, styles and sizes of windows and local labor costs.
Which type of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
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, since rain can make the installation more difficult.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows at once is the only way to gain that benefit. However, if you have only one or two windows that are damaged or leaky, you can replace just those.
