How Installing Energy-Efficient Windows in Weldon Spring Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:

  • Save money on electricity bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.
  • Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Weldon Spring

Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

Though the typical of replacing one window is about $600, it can range anywhere from $200 to $1,200. These amounts vary based on specific characteristics of your installation, including size, number of windows, the location of your home, material, type and more.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Requesting free quotes from multiple installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

In general, there are two types of window installation services you can get: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has significant deterioration. With this service, your professionals will replace the total window, including the trim, sill and frame. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you're not sure which kind of window installation service you need, your installer can advise you. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Weldon Spring

In our hunt to find the most reliable, eco-friendly window installers in Weldon Spring, the EcoWatch Reviews team examined many companies before settling on these. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Weldon Spring, we paid more attention to companies that provide services to 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 picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, quality of parts, warranty, professionalism, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why 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 been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Weldon Spring, MO Window Replacement FAQs

How much should a window install cost?

The national average cost to install a window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the kinds of windows?

The most common types of windows for homes include: awning windows, bay windows, double-hung and single-hung windows, transom windows, picture windows, slider windows and casement windows.

When do I have to use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.

How do you know it's time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
