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- Protect your investment: If your home is on the older side, your windows are most likely outdated.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 expect that most replacement window installations will cost between $250 and $1,200, with the most common installations 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.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has significant rot. Because these installations are more involved, they will raise the overall cost. A pocket installation means replacing a window without removing the entire frame, which is generally cheaper than a full-frame installation.
If you’re still trying to decide which kind of installation you should get, you can consult with your installer and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Union
EcoWatch reviews are different from most reviews, as we evaluate these companies through a sustainability lens. We have decided to review the best window installers in Union mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
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 they wouldn’t be able to serve homeowners in Union.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, quality of parts, professionalism, warranty, quality of installation and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we gave higher points 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 labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers 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
How much does a window install cost?
The typical cost of installing one window can range between $450 and $650. There are a variety of factors that affect the cost, which include how energy-efficient the windows are, local labor costs, your property’s location, the materials used in designing the windows, styles and sizes of windows and the number of windows.
What are the most common types of replacement windows?
There are various types of windows you can get for your house, such as transom windows, picture windows, awning windows, double-hung and single-hung windows, bay windows, slider windows and casement windows.
Do I really need to use a window installation company?
You should hire a window installation professional whenever you want to replace your windows. Installing windows is a complicated process that can take a lot of time, so it’s best handled by the professionals.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
How long does it take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.
