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

When you switch to energy-efficient windows, you may see several benefits, such as:

• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
• Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that number, which helps you save some money on your bills.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Mount Pleasant

When considering window installation, each company offers varying services and costs. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

On average, Mount Pleasant homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost is based on several factors, such as number of windows, type, the location of your home, size, material and more.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $331 a year on your energy bills in Mount Pleasant.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames have the lowest price. 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 with 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?

The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. These installations are more involved and will raise the overall cost. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

If you’re still debating which kind of installation to get, you can talk to your provider and get their recommendation. The decision mostly depends on the age of your window frames and if there’s any damage.
