How Installing Energy-Efficient Windows in Sugar Loaf Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to consider making the switch:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: In Sugar Loaf, you can cut your indirect greenhouse gas emissions by about 642 pounds per year when you install energy-efficient windows.
Estimated Cost of Window Replacement in Sugar Loaf
When researching window installation, each company offers different services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. This is because window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $316 a year on your energy bills in Sugar Loaf.
Costs will also vary depending on the material you want for your window frames. 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 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 step when considering an installation is to think about whether you want a full-frame or pocket installation.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Sugar Loaf
EcoWatch is different from other reviewers, as we're examining these companies through a sustainability lens. We've reviewed the top window replacement companies in Sugar Loaf mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Sugar Loaf, we gave more points to companies that cover the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Sugar Loaf.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured on this list to make sure its contractors are well-qualified and that the company has gotten a lot 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 installer, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Sugar Loaf's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Sugar Loaf window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Sugar Loaf, IL Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost of replacing one window can range between $450 and $650. There are many factors that influence the price, such as local labor costs, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, your property's location and styles and sizes of windows.
Which kind of window is the best?
A window's energy efficiency is influenced by a variety of factors, including 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 experience with installing a replacement window, it's possible to install your own windows. However, if you don't have the time or experience, we recommend hiring a professional.
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 make sure that too much hot or cold air doesn't get into the house, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
