How Installing Energy-Efficient Windows in Lockport Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to think about making the switch:
- Save money on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll need less energy to heat or cool your home.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 449 pounds.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Lockport
Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Generally, Lockport homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But prices differ remarkably based 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 make your project cost more.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lockport homeowners $307+ per year after replacing single-pane windows.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using 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 thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without replacing the frame. This means instead of taking out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which kind of installation you need, you can ask your provider and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Lockport
In our hunt to make your home improvements easier and more eco-friendly in Lockport, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Lockport, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Lockport.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, quality of parts, warranty, professionalism, cost 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. Still, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Lockport's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Lockport window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Lockport, IL Window Replacement FAQs
How much does window installation cost?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, depending on several factors. The price is generally dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies do?
Window installers go to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How long does window installation take?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.
What time of year should I replace my windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the 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.
