How Installing Energy-Efficient Windows in Weldon Spring Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, such as:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Save on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
Estimated Cost of Window Replacement in Weldon Spring
When considering window installation, each company provides varying services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which have a higher price tag.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
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 thing to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
If you're still trying to decide which kind of installation you should get, you can talk to your installer and get their advice. The choice mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Weldon Spring
EcoWatch is different from most reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:
Service Area
Because this is a guide for Weldon Spring, we paid more attention to companies that cover the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Weldon Spring.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of installation, cost, quality of parts, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
