Estimated Cost of Window Replacement in Florissant

Let’s take a look at the cost of window installation and the kinds of services offered by installers.

How Much Do New Windows Cost?

The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost is based on several factors, like type, the location of your home, material, number of windows, size and more.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Florissant homeowners $376+ each year after 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 completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When it comes to window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the trim, sill and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage. Because these installations are more involved, they will increase the overall cost. Pocket installations are simpler and won’t cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can help you choose which type of installation you need.

Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Florissant area so you can find the best window installation company near you.

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 on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive things to say about their experience with 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 want to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
