How Installing Energy-Efficient Windows in Frederick Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Frederick
When researching window installation, each company offers different services and prices. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
According to our market research, the national average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. But costs differ remarkably depending 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.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations entail replacing the full window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Because these installations are more involved, they will increase the overall cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Frederick
EcoWatch reviews are different from other reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Frederick and assigned rankings using the following methodology:
Service Area
Since this is a guide for Frederick, we gave more points to companies that serve the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Frederick.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have good feedback about their service from a certain installer, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t 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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Frederick’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Frederick window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Frederick, MD Window Replacement FAQs
How much should window installation cost?
The average cost of replacing one window ranges from $450 to $650. There are many factors that affect how much it costs, which include the materials used in designing the windows, your property’s location, styles and sizes of windows, the number of windows, how energy-efficient the windows are and local labor costs.
Which kind of window is the best?
A window’s energy efficiency is influenced by a variety 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.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have all the necessary tools to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
When is it time to replace your windows?
Windows generally have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have an expert take a look at them to see if they are in need of a repair or replacement.
