How Installing Energy-Efficient Windows in Rock Falls Saves You Money

When you upgrade to energy-efficient windows, you may see a few benefits, such as:

  • Better temperature control in your home: Residing in a very cold place like Rock Falls often means relying on your heater to keep your house cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Installing energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • 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 because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Rock Falls

When considering window installation, each company offers varying services and costs. Let's go over some average costs and services.

How Much Do New Windows Cost?

On average, homeowners in Rock Falls can anticipate that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will add extra costs to your project.

It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your Rock Falls home translates to 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. How much you'll save by upgrading 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 cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with 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 step of a window installation is to think about whether you want a full-frame or pocket installation.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations are simpler and won't carry as large a bill, as they entail 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 will be able to help you understand what's best for your needs. In Rock Falls, the decision will mostly be based on how old your home is and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Rock Falls

EcoWatch differs from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Rock Falls and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Rock Falls, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Rock Falls.

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Rock Falls, IL Window Replacement FAQs

What is the typical cost to replace windows?

The typical cost of replacing a window can range between $450 and $650. There are a variety of factors that influence how much it costs, such as local labor costs, the materials used in designing the windows, your property's location, the number of windows, styles and sizes of windows and how energy-efficient the windows are.

Which kind of window is the best?

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

When should I use a window installation company?

Unless you're handy and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.

When is the best time of year to replace 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 more important than the temperature is that the weather should be dry.
