How Installing Energy-Efficient Windows in Pontiac Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Pontiac
Windows come in various shapes and sizes, so costs and services will differ considerably. Here are the average costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
According to our market research, the national average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. Costs will differ significantly based on your location, the quality of your products, the number of windows you need and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, although it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the entire window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installation company will be able to help you decide what’s best for your needs. In Pontiac, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Pontiac
The EcoWatch Reviews team is different from other reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good things to say 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 try 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. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Pontiac’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Pontiac window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Pontiac, IL Window Replacement FAQs
How much does window installation cost?
The typical cost of replacing a single window can range between $450 and $650. There are a variety of factors that affect the cost, such as styles and sizes of windows, how energy-efficient the windows are, local labor costs, your property’s location, the materials used in designing the windows and the number of windows.
Which type of window should I get?
A window’s energy efficiency is influenced 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.
What do window installers do?
Window installers will do the entire process — from replacing your old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.
How long does window installation take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.
