How Installing Energy-Efficient Windows in Beloit Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could help you:
- 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.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Beloit, that's about 715 pounds per year on average.
- Save money on energy bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your home.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Beloit
When researching window installation, each company provides different services and prices. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the national average cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
It's also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Beloit home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. So, instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're not sure which kind of window installation service you need, your installer can advise you. Generally, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Beloit
In our hunt to find the most reliable, eco-friendly window installers in Beloit, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We have evaluated the top window installation companies in Beloit mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Beloit, we only included companies that provide services to the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Beloit.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer on this list to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a significant investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Beloit, WI Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost of replacing a single window can range from $450 to $650. There are many factors that influence the cost, including styles and sizes of windows, how energy-efficient the windows are, your property's location, the number of windows, the materials used in designing the windows and local labor costs.
Which kind of window should I get?
A window's energy efficiency is influenced by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window installation companies offer?
Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
How long does it usually take to install windows?
Since a window takes about 30 minutes to install, around 16 windows can be installed during an 8-hour work day.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, the weather should be dry, as rain can make the installation harder.
