How Installing Energy-Efficient Windows in Union Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, such as:

  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 415 pounds.
  • Save money on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $391 annually on your energy bills in Union.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Union

Windows come in different purposes, shapes and styles, so costs and services will vary remarkably based on several factors. Below, we go over the typical cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

According to our research, the average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. But prices differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will make your project cost more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Union homeowners $391+ per year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer 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 offer decent insulation for your home.

What Services do Window Installers Offer?

In regard to window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage. Full-frame installations are more involved and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

Your window replacement company will be able to help you choose what's best for your needs. In Union, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Union

In our hunt to find the most reliable, eco-friendly window installers in Union, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Union, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Union.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured on this list to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have nice things to say about their experience with a certain installer, you won't see it featured on EcoWatch.

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 providers' prices, we gave 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Union, SC Window Replacement FAQs

What is the average cost to replace windows in a home?

The national average cost of replacing one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the different types of windows?

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

Can I install 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 installation is done properly and that you won't have to spend the time and effort to do it yourself.

What time of year is the best time to replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.

Should I replace all my windows at the same time?

If you're upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to gain that benefit. However, if you have only a few windows that are broken or drafty, you can replace just those.
