How Installing Energy-Efficient Windows in Sugar Loaf Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 642 pounds.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Sugar Loaf
Windows come in various shapes, purposes and styles, so costs and services will vary tremendously based on several factors. Below, we go over the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Generally, Sugar Loaf homeowners can expect their window installations to range from $250 to $1,200. The average cost is at approximately $600. These numbers are based on specific characteristics of your installation, like the location of your home, number of windows, material, size, type and more.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Requesting free quotes from multiple installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot or deterioration. Full-frame installations are more involved and will increase the overall cost. A pocket installation involves replacing a window within the existing frame. This means instead of tearing out 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 hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Sugar Loaf, the decision will mostly depend on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Sugar Loaf
The EcoWatch Reviews team is different from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Sugar Loaf and ranked them based on the following methodology:
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 our list 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 tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, professionalism, quality of installation, cost, quality of parts and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Sugar Loaf's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Sugar Loaf window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Sugar Loaf, IL Window Replacement FAQs
How much should window installation cost?
The national average cost to install one window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically dependent on the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes are casement windows, double-hung and single-hung windows, awning windows, transom windows, picture windows, slider windows and bay windows.
Can you replace your 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 know-how, we recommend hiring a professional.
How long does window installation take?
Because a window takes about 30 minutes to install, around 16 windows can be installed during an 8-hour work day.
Should I replace all my windows at once?
If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
