How Installing Energy-Efficient Windows in Severna Park Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Severna Park, that’s about 249 pounds per year on average.
Estimated Cost of Window Replacement in Severna Park
Let’s take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is because window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step of an installation is to think about whether you should get a full-frame or pocket installation.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations are simpler and won’t carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re unsure which window installation service you should get, your installer should be able to advise you. Generally, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Severna Park
In our hunt to make your home improvements easier and more eco-friendly in Severna Park, the EcoWatch Reviews team assessed many companies before settling on these. We have evaluated the top window installation companies in Severna Park mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Severna Park area so you can find a quality window installation company near you.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. 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 very important review factor. If most customers don’t have nice things to say about their service from 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 try to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Severna Park’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Severna Park window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Severna Park, MD Window Replacement FAQs
What is the average cost to install windows in a home?
The average cost of replacing one window ranges from $450 to $650. There are several factors that affect the cost, which include the materials used in designing the windows, how energy-efficient the windows are, your property’s location, local labor costs, the number of windows and styles and sizes of windows.
Which type of window is the best?
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 typically the most energy-efficient and are certified by the U.S. Department of Energy.
When do I need to use a window installation company?
You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best handled by the professionals.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
