How Installing Energy-Efficient Windows in Mendham Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 206 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Save money on energy 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 that amount, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Mendham
Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from window installers.
How Much Do New Windows Cost?
Typically, Mendham homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at approximately $600. But costs will differ significantly based on the quality of your products, your location, the current condition of your home and the number of windows you need. Many window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Mendham homeowners $287+ each year after replacing single-pane windows.
Getting free quotes from multiple providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot or deterioration. Because full-frame installations are more involved, they will raise the overall cost. A pocket installation entails installing a new window within the existing frame. This means instead of tearing out the whole unit and rebuilding it, the window installer will just slide 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 Mendham, the decision will mostly be based on how old your windows are and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Mendham
In our hunt to make your home improvements easier and more eco-friendly in Mendham, the EcoWatch team assessed many companies before deciding on these. We've decided to review the best window installers in Mendham mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy 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 Mendham area so you can find a quality window installation company near you.
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 on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, cost, quality of installation, quality of parts, professionalism and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies may not provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Mendham, NJ Window Replacement FAQs
What is the typical cost to replace windows in a home?
The typical cost to replace a window can range from $450 to $650. There are a variety of factors that influence the cost, including the materials used in designing the windows, your property's location, styles and sizes of windows, how energy-efficient the windows are, the number of windows and local labor costs.
Which kind of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with 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're handy and have the tools needed to replace your own windows, we recommend hiring the pros. The process of installing windows is complicated 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 professional is a faster, more efficient and much safer option.
What time of year should I replace my windows?
Though you can install windows any time of year, warmer weather is often better for replacing windows. In addition, it shouldn't be raining, as rain can make the installation harder.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
