How Installing Energy-Efficient Windows in Union Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to consider making the switch:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
  • Decrease your carbon footprint: In Union, you can lower your indirect greenhouse gas emissions by about 763 pounds per year once you upgrade to energy-efficient windows.
  • Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Union

Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the typical costs and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Although the average to replace a single window is about $600, it can range from $200 to $1,200. How much it will cost you is based on several factors, like size, type, number of windows, the location of your home, material and more.

It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Union home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material you want for your window frames. 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 from 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?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. 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 rot, you may need a full-frame installation instead.

Your window installation company should be able to help you decide what's best for your needs. In Union, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if it's not maintained properly 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

EcoWatch reviews are different from other reviews since we're examining these companies through a sustainability lens. We've reviewed the top window installation companies in Union primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Union, we only included companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Union.

Work Quality

When it comes to new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you choose. 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

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Union, MO Window Replacement FAQs

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

The typical cost to replace one window ranges between $450 and $650. There are a variety of factors that influence how much it costs, which include styles and sizes of windows, local labor costs, your property's location, the materials used in designing the windows, the number of windows and how energy-efficient the windows are.

What are the most common types of replacement windows?

There are several different kinds of windows you can get for your home, including casement windows, slider windows, transom windows, bay windows, double-hung and single-hung windows, awning windows and picture windows.

Do I really have to use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer alternative.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.

When is it time to replace your windows?

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