How Installing Energy-Efficient Windows in Mount Holly Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 345 pounds per year on average.
- 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.
- Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Mount Holly
Windows come in varying purposes, shapes and styles, so costs and services will vary remarkably based on several factors. Below, we describe the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Typically, Mount Holly homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. This is because window installations depend on several 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.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Mount Holly homeowners $343+ each year after replacing single-pane windows.
Asking for free quotes from multiple installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your professionals will replace the total window, including the frame, sill and trim. Pocket installations are on the simpler end and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company will be able to help you figure out what’s best for your needs. In Mount Holly, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Mount Holly
The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Mount Holly and assigned rankings using the following methodology:
Service Area
Because this is a guide for Mount Holly, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Mount Holly.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of installation, warranty, quality of parts, cost and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as 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 protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
