How Installing Energy-Efficient Windows in St Ann Saves You Money
There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Save on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
- Decrease your carbon footprint: In St Ann, you can cut your indirect greenhouse gas emissions by about 763 pounds per year once you upgrade to energy-efficient windows.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in St Ann
When considering window installation, each company provides different services and costs. Let's go over some typical costs and services.
How Much Do New Windows Cost?
Though the typical of replacing a single window is about $600, it can range anywhere from $200 to $1,200. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which carry a higher price tag.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save St Ann homeowners $376+ a year when replacing single-pane windows.
We recommend requesting free quotes from several window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable deterioration. Because full-frame installations are more involved, they will increase the total cost. A pocket installation entails installing a new window within the existing frame. This means instead of tearing out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which type of installation to get, you can ask your provider and get their advice. The choice mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in St Ann
In our search to find the most reliable, eco-friendly window installers in St Ann, the EcoWatch team landed on the above companies as the best window installation companies in the city. We've decided to assess the best window replacement companies in St Ann mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for St Ann, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in St Ann.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have positive things to say about their service from a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to St Ann's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of St Ann window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
St Ann, MO Window Replacement FAQs
