How Installing Energy-Efficient Windows in Mount Prospect Saves You Money
Upgrading 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: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 449 pounds.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way.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 Mount Prospect
When considering window installation, each company offers varying services and costs. Let’s take a look at some typical costs and services.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.
Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $295 a year on your energy bills in Mount Prospect.
Another factor that influences the total cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
Your window replacement company should be able to help you understand what’s best for your needs. In Mount Prospect, the decision will mostly depend on the age of your home and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Mount Prospect
EcoWatch reviews differ from most reviews, as we examine these companies through a sustainability lens. We’ve evaluated the top window replacement companies in Mount Prospect mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. 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 Mount Prospect, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Mount Prospect.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including cost, quality of parts, professionalism, quality of installation, warranty and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try 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
As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Mount Prospect, IL Window Replacement FAQs
How much does a window install cost?
The average cost of replacing a single window can range from $450 to $650. There are many factors that affect the cost, which include the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, the number of windows, your property’s location and local labor costs.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: awning windows, transom windows, slider windows, casement windows, double-hung and single-hung windows, bay windows and picture windows.
When should I use a window installation company?
Unless you have experience with home improvement projects and have all the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
How long does window installation typically take?
