How Installing Energy-Efficient Windows in Irmo Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to think about making the switch:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way.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.
• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
• Reduce your carbon footprint: By using less energy once you switch to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Irmo

Let’s take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

Generally, Irmo homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. Costs will differ considerably based on the number of windows you need, your location, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Irmo homeowners $393+ 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 maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window installation is to clarify whether you should get a full-frame or pocket installation.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

If you’re not sure which kind of window installation service you should get, your installer should be able to help you out. Generally, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Irmo

EcoWatch reviews are different from most reviews since we assess these companies through a sustainability lens. We’ve evaluated the top window installers in Irmo primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your power 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 Irmo, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Irmo.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, warranty, quality of parts, cost, quality of installation and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Irmo’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Irmo window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
