• Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.

Estimated Cost of Window Replacement in South St. Paul

Windows come in different purposes, styles and shapes, so costs and services will vary tremendously depending on several factors. Below, we detail the average cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

According to our market research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. These figures are based on specific characteristics of your installation, including the location of your home, type, size, number of windows, material 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 install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Because these installations are more involved, they will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re still debating which kind of installation you need, you can talk to your provider and get their advice. The choice mostly depends on how old the frames are and if there’s any damage present.

Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for South St. Paul, 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 South St. Paul.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer included on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have nice things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

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