Why you can trust EcoWatch
A guide on the best window replacement companies in Troy may not seem like the most compelling article on EcoWatch, but trust us, windows impact your life more than you might think. The Department of Energy estimates that heat or cool air lost through traditional or outdated windows could make up around 30% of heating and cooling costs. In Troy, where the power bills are an average of $39 per month, that's almost $$140 per year wasted.
That's also bad news for the environment, as the additional energy used by outdated windows increases your carbon footprint.
As windows are so important for your home, choosing the right company for you is a big choice to make. That's why the EcoWatch team has curated this list of the best window installation companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Troy Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, including:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Better temperature control in your home: Energy-efficient windows can lower how much heat is lost through your windows when heating your home.
- Save on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Troy
Windows come in varying shapes and sizes, so costs and services will vary remarkably. Here are the average costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range from $200 to $1,200. These estimates are based on the specifics of your installation, including material, type, the location of your home, number of windows, size and more.
Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $383 a year on your energy bills in Troy.
We recommend getting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
Your window installation company will be able to help you choose what's best for your needs. In Troy, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Troy
In our search to find the most reliable, eco-friendly window installers in Troy, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:
Service Area
Because this is a guide for Troy, we paid more attention to 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 Troy.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of parts, professionalism, cost, quality of installation and more.
Cost
This one is a give-and-take: as with most services, cheap window installers won't always provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
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
Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Troy, MO Window Replacement FAQs
How much should window installation cost?
The average cost to install a single window can range between $450 and $650. There are many factors that affect the price, which include local labor costs, the number of windows, styles and sizes of windows, your property's location, how energy-efficient the windows are and the materials used in designing the windows.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: picture windows, bay windows, casement windows, awning windows, slider windows, double-hung and single-hung windows and transom windows.
Do I really need to use a window installation company?
You should hire a window installation professional whenever you need new windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best left to the professionals.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows together is the only way to gain that benefit. However, if you have just one or two windows that are damaged or leaky, you can replace just those.
