How Installing Energy-Efficient Windows in Beloit Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could help you:

  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
  • Decrease your carbon footprint: In Beloit, you can cut your indirect greenhouse gas emissions by about 715 pounds per year after you upgrade to energy-efficient windows.
  • Save on electricity bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save around $483 annually on your energy bills in Beloit.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Beloit

Each window installation company offers various services and has varying price points based on a few factors.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range from $200 to $1,200. But costs differ remarkably 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 will make your project cost more.

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

Getting free quotes from multiple providers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies offer: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has noticeable rot or deterioration. Because these installations are more involved, they will raise the total cost. Pocket installations are simpler and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Beloit

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

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you choose. 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

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, professionalism, warranty, quality of installation, cost and more.

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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Beloit’s climate, homeowners will want to mitigate rot, low efficiency and water damage. 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 typical cost to install windows?

The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What type of window is the best for energy efficiency?

A window’s energy efficiency is affected by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

Can I install my own windows?

If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or skills, we recommend hiring a professional.

What time of year is a good time to replace my windows?

Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.

How long does it generally take to install windows?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.
