How Installing Energy-Efficient Windows in Mount Pleasant Saves You Money

When you switch to energy-efficient windows, you may see several perks, including:

  • Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save money on energy bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.

Estimated Cost of Window Replacement in Mount Pleasant

Windows come in various styles, purposes and shapes, so costs and services will differ considerably based on your project. Below, we describe the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Typically, Mount Pleasant homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at about $600. These amounts are based on specific characteristics of your installation, like the location of your home, number of windows, size, material, type and more.

It’s important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Mount Pleasant homeowners $313+ a year when replacing single-pane windows.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also offer 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?

There are generally two kinds of window installation services: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the complete window, including the sill, frame and trim. Pocket installations are on the simpler end and won’t cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

If you’re still trying to decide which type of installation you need, you can ask your installer and get their advice. The choice mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Mount Pleasant

In our search to find the most reliable, eco-friendly window installers in Mount Pleasant, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We’ve decided to review the top window installers in Mount Pleasant mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Mount Pleasant, we gave more points to companies that cover the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Mount Pleasant.

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 installer included in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of 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, quality of installation, quality of parts, warranty, professionalism and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like 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. That’s why window installation companies that provide 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 a while. 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, SC Window Replacement FAQs

How much does a window install cost?

The typical cost to install a single window ranges between $450 and $650. There are several factors that affect the price, which include the materials used in designing the windows, local labor costs, styles and sizes of windows, how energy-efficient the windows are, the number of windows and your property’s location.

What are the types of windows?

The most common types of windows for homes include: bay windows, awning windows, double-hung and single-hung windows, casement windows, transom windows, picture windows and slider windows.

Can I replace my own windows?

Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

How often do you need to replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
