Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. Drafty, leaky windows can cost you in power bills. As a matter of fact, the Department of Energy estimates that about 30% of your house's heat or cool air could be lost through your windows.

Fortunately, saving you money with efficient windows also helps our goals of conserving energy and the resources it takes to produce it.

Unlike other review sites, EcoWatch ranks window companies on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Beloit Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, including:

  • More efficient energy usage in your household: Because the winters can get very cold in Beloit, homeowners usually depend on their heater a lot. Energy-efficient windows reduce the amount of heat that is lost through your windows, making it easier to keep your home warm.
  • Save on electricity bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $483 annually on your energy bills in Beloit.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which 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 real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Beloit

Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you'll find from window installation companies.

How Much Do New Windows Cost?

The national average cost to replace one window is about $600 but can range from $200 to $1,200. This is due to the fact that window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $483 a year on your energy bills in Beloit.

Costs will also vary based on the material you pick 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 offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive 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 thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won't cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

If you're not sure which kind of window installation service you should get, your installer can advise you. In general, the choice is based on 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

EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Beloit and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say about their service from a certain installer, it won't be 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 providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Beloit, WI Window Replacement FAQs

What is the average cost to install new windows?

The national average cost to replace a single window is around $600 but can range from $200 to $1,200, based on several factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the different kinds of windows?

The most common kinds of windows for homes include: transom windows, slider windows, casement windows, picture windows, awning windows, double-hung and single-hung windows and bay windows.

When do I have to use a window installation company?

You should use a window installation company whenever you need to replace your windows. Installing windows is a involved process that can take a lot of time, so it's best left to the professionals.

Should I replace my windows all at the same time?

If you're upgrading your windows because of energy-efficiency, replacing all of your windows together is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
