Estimated Cost of Window Replacement in Glen Carbon

Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

According to our research, the typical cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because the cost of window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Glen Carbon homeowners $313+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

In regard to window installations, in general there are two types that your installer will offer: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage. These installations are more involved and will increase the overall cost. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Glen Carbon, the decision will mostly be based on the efficiency of your home and the age and condition of your existing frames.

Energy Star certified windows have been shown to 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 Glen Carbon, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Glen Carbon.

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 included on this list to ensure its contractors are well-qualified and that the company has gotten tons 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 nice feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a hefty investment, so you’ll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
