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

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to think about making the switch:

• Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating 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 from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Mount Pleasant

When researching window installation, each company provides different services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Generally, homeowners in Mount Pleasant can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs differ remarkably 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 provide door installations and replacements, which will make your project cost more.

It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Mount Pleasant homeowners $293+ a year when replacing single-pane windows.

Requesting free quotes from multiple companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

When it comes to window replacements, there are generally two types that your installer will have: full-frame and pocket installations.

Full-frame installations entail replacing the total 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 noticeable rot. Because these installations are more involved, they will increase the total cost. Pocket installations are on the simpler end and won’t cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Mount Pleasant

The EcoWatch Reviews team differs from other reviewers since we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Mount Pleasant and assigned rankings using the following methodology:

Service Area

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

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window 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

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have nice things to say about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Mount Pleasant’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Mount Pleasant window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
