How Installing Energy-Efficient Windows in Fairland Saves You Money
There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
Estimated Cost of Window Replacement in Fairland
Let’s take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.
It’s also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your Fairland home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material you want for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations are more involved and will increase overall costs. A pocket installation entails replacing a window without replacing the frame. This means instead of removing the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to help you understand what’s best for your needs. In Fairland, the decision will mostly be based on the age of your windows and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Fairland
In our search to find the most reliable, eco-friendly window installers in Fairland, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We have evaluated the top window installation companies in Fairland primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your power 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 Fairland, we paid more attention 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 Fairland.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand 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 customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, quality of parts, professionalism, quality of installation, cost and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Fairland’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Fairland window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Fairland, MD Window Replacement FAQs
What is the average cost to replace windows?
The national average cost to install a window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
A window’s energy efficiency is affected by several 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 since they are certified by the U.S. Department of Energy.
When do I need to 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 a professional. 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 save money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
Should I replace my windows all at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
