How Installing Energy-Efficient Windows in Frederick Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, such as:
- 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $294 annually on your energy bills in Frederick.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Frederick
Windows come in varying purposes, shapes and styles, so costs and services will differ tremendously depending on your project. Below, we describe the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, Frederick homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These numbers vary based on specific characteristics of your installation, like material, type, the location of your home, number of windows, size and more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Requesting free quotes from multiple companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies offer: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the trim, sill and frame. A pocket installation means replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Frederick
In our search to make your home improvements easier and more eco-friendly in Frederick, EcoWatch evaluated dozens of companies before landing on these. We’ve decided to evaluate the top window replacement companies in Frederick mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your 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 Frederick, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Frederick.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their service from a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Frederick’s climate, homeowners need to be wary of low efficiency, water damage and rot. 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
What is the average cost to install windows?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on several factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.
Do I really have to use a window installation company?
Unless you have home repair skills 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 a single window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer option.
How often should you replace windows?
Windows usually 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 determine if they are in need of a repair or replacement.
Should I replace my windows all at the same time?
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 one or two windows that are broken or drafty, you can replace just those.
