20 Best Window Companies in Union, MO (2025 Reviews)

How Installing Energy-Efficient Windows in Union Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:

• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your carbon footprint by about 12%, according to Energy Star.
• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce 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• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Union

Each window installation company provides varying services and has varying prices based on a few factors.

How Much Do New Windows Cost?

Typically, homeowners in Union can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at about $600. This is because window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Union homeowners $374+ a year when replacing single-pane windows.

Something else that affects the total cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

When considering window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. 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, you may have to get a full-frame installation instead.

Your window installation company can help you choose which type of installation you need.
