12 Best Window Companies in Hermantown, MN (2025 Reviews)

How Installing Energy-Efficient Windows in Hermantown Saves You Money

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

• Save money on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
• Decrease your carbon footprint: In Hermantown, you can reduce your indirect greenhouse gas emissions by about 519 pounds per year when you install energy-efficient windows.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Hermantown

When looking into window installation, each company offers different services and prices. Let’s look at some average costs and services.

How Much Do New Windows Cost?

The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which have a higher price tag.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Hermantown homeowners $607+ per year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with 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 offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a replacement is to think about whether you need a full-frame or pocket installation.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the entire window, including the trim, frame and sill. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

Your window replacement company should be able to help you figure out what’s best for your needs. In Hermantown, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Hermantown

EcoWatch differs from most reviewers since we examine these companies through a sustainability lens. We have reviewed the best window installation companies in Hermantown mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Hermantown area so you can find a quality window installation company near you.

Work Quality

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

Customer Reviews

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

Cost

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

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Hermantown’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Hermantown window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
