• Save money on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In DeForest, that’s about 715 pounds per year on average.

Estimated Cost of Window Replacement in DeForest

Each window replacement company offers various services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range from $200 to $1,200. These figures are based on the specifics of your installation, like type, size, material, the location of your home, number of windows and more.

It’s also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your DeForest home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

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 provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer 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?

In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot. Because these installations are more involved, they will raise the total cost. A pocket installation means replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

If you’re not sure which type of window installation service you should get, your installer should be able to assist you. Generally, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

We’ve reviewed the top window installation companies in DeForest mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for DeForest, we only included 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 DeForest.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured on this list to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have positive things to say about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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