How Installing Energy-Efficient Windows in Lasalle Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that amount, which helps you save more on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Decrease your carbon footprint: In Lasalle, you can cut your indirect greenhouse gas emissions by about 642 pounds per year once you switch to energy-efficient windows.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in Lasalle
Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, homeowners in Lasalle can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. But costs will vary considerably based on the number of windows you need, the quality of your products, your location and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
With windows, efficiency is one of the most important factors for many 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 provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lasalle homeowners $308+ each year after replacing single-pane windows.
We advise requesting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step when planning a window replacement is to decide whether you want a full-frame or pocket installation.
A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the overall cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window installation company will be able to recommend the best type for your project. In Lasalle, the choice will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Lasalle
In our search to make your home improvements easier and more eco-friendly in Lasalle, the EcoWatch Reviews team evaluated many companies before landing on these. We've assessed the best window installation companies in Lasalle mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Lasalle, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Lasalle.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide 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 customer feedback to find the companies with the most consistent 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 nearly every category, including warranty, quality of parts, cost, professionalism, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a sizable investment, so you'll want to make sure that investment is protected. Window installation companies that give you 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 good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Lasalle, IL Window Replacement FAQs
How much should a window install cost?
The average cost to replace a window can range between $450 and $650. There are many factors that influence how much it costs, which include your property's location, local labor costs, the materials used in designing the windows, the number of windows, styles and sizes of windows and how energy-efficient the windows are.
What are the most common types of replacement windows?
The most common types of windows for homes are double-hung and single-hung windows, slider windows, casement windows, awning windows, picture windows, transom windows and bay windows.
Can you replace your own windows?
While you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year should I replace my windows?
Although you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation harder.
Should I replace my windows all at once?
If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
