How Installing Energy-Efficient Windows in Kirkwood Saves You Money

When you switch to energy-efficient windows, you may see several perks, such as:

• Save on energy bills: Since energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $376 annually on your energy bills in Kirkwood.
• Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Kirkwood

Windows come in different shapes, styles and purposes, so costs and services will vary tremendously based on several factors. Below, we detail the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

Even though the average cost to install one window is about $600, it can range from $200 to $1,200. But costs will differ considerably based on your location, the current condition of your home, the number of windows you need and the quality of your products. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.

It’s important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Kirkwood homeowners $376+ a year when replacing single-pane windows.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, although it depends on whether they are completely 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?

The first step of a replacement is to decide whether you want a full-frame or pocket installation.

Full-frame installations are usually recommended when you want a new style or your window has significant deterioration. With this service, your installers will replace the total window, including the sill, frame and trim. A pocket installation involves installing a new window within the old frame. So, instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Kirkwood, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Kirkwood

In our hunt to make your home improvements easier and more eco-friendly in Kirkwood, the EcoWatch team evaluated many companies before landing on these. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Kirkwood, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Kirkwood.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list 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

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive things to say about their experience with a certain company, you won’t see it featured on EcoWatch.

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 the prices of providers, 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 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
