How Installing Energy-Efficient Windows in St. Louis Park Saves You Money

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

• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in St. Louis Park

Let’s take a look at the cost of updating your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

On average, St. Louis Park homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. These numbers are based on the specifics of your installation, like type, number of windows, size, the location of your home, material and more.

It’s important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save St. Louis Park homeowners $505+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most 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 general, there are two kinds of window installation services companies offer: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In St. Louis Park, the decision will mostly depend on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in St. Louis Park

EcoWatch reviews are different from most reviews since we’re examining these companies through a sustainability lens. We have assessed the top window installers in St. Louis Park mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for St. Louis Park, we only included companies that cover the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in St. Louis Park.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have positive things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
