How Installing Energy-Efficient Windows in Mount Pleasant Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, such as:
- Better temperature control in your home: Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
- Reduce your carbon footprint: In Mount Pleasant, you can cut your indirect greenhouse gas emissions by about 467 pounds per year once you upgrade to energy-efficient windows.
- Better temperature control in your home: Energy-efficient windows can decrease the amount of cool air lost through your windows when cooling your home.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Mount Pleasant
Let's take a look at the cost of window installation and the kinds of services you may need for your home.
How Much Do New Windows Cost?
Although the typical to install one window is around $600, it can range from $200 to $1,200. How much it will cost you depends on several factors, like number of windows, size, type, material, the location of your home and more.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Mount Pleasant home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by switching 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 choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step of an installation is to decide whether you need a full-frame or pocket installation.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the full window, including the trim, sill and frame. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're still debating which type of installation you need, you can consult with your provider and get their advice. The decision mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Mount Pleasant
The EcoWatch Reviews team is different from other reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services often plays 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including cost, professionalism, warranty, quality of installation, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, 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. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) 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 installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Mount Pleasant, PA Window Replacement FAQs
What is the typical cost to replace windows in a home?
The typical cost of replacing a single window can range from $450 to $650. There are many factors that influence the cost, including your property's location, how energy-efficient the windows are, the number of windows, the materials used in designing the windows, local labor costs and styles and sizes of windows.
What are the different types of windows?
There are various types of windows you can get for your home, such as awning windows, bay windows, slider windows, double-hung and single-hung windows, casement windows, transom windows and picture windows.
What do window installation companies do?
Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How often should you 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 open or close, they may need to be replaced.
