How Installing Energy-Efficient Windows in White Oak Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to consider making the switch:
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help decrease how much you have to pay, 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 harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In White Oak, that’s about 234 pounds per year on average.
Estimated Cost of Window Replacement in White Oak
Each window installer offers varying services and has different price points based on several factors.
How Much Do New Windows Cost?
According to our market research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
It’s also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star predicts that switching out the windows on your White Oak home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that influences the overall cost is the material of the frame you pick. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services you can get: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in White Oak
The EcoWatch Reviews team differs from other reviewers, as we examine these companies through a sustainability lens. We have decided to review the top window replacement companies in White Oak mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the White Oak area so you can find the best window installation company near you.
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 featured in our guide to ensure 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 super important review factor. If most customers don’t have good feedback about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a hefty investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to White Oak’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of White Oak window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
White Oak, MD Window Replacement FAQs
How much does window installation cost?
The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the kinds of windows?
There are several different kinds of windows you can get for your home, such as picture windows, awning windows, bay windows, double-hung and single-hung windows, transom windows, slider windows and casement windows.
When should I use a window installation company?
Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for one 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?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
How long does it take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed during an 8-hour work day.
