Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's efficiency can also have a large impact on home energy conservation. The Department of Energy estimates that heat gained or lost through traditional or outdated windows could account for close to 30% of heating and cooling usage. In LaSalle, where the electric bills are an average of $32 per month, that's almost $$117 per year wasted.
Installing energy-efficient windows on your property can help you save money each month on your power bills — and you can help the environment as well.
So if you're building a new home, renovating or replacing your windows in LaSalle, this guide is the best place to get started.

How Installing Energy-Efficient Windows in LaSalle Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could help you:
- More efficient energy usage in your home: In LaSalle where the winters can be very cold, energy-efficient windows lower how much heat is lost through your windows, making it easier to keep your house warm.
- Protect your valuables from fading: When you switch 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.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
- Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save $308 a year on your bills.
Estimated Cost of Window Replacement in LaSalle
Windows come in various shapes, styles and purposes, so costs and services will vary considerably depending on several factors. Below, we go over the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
Typically, homeowners in LaSalle can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. This is because window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly 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.
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, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has noticeable rot or deterioration. Full-frame installations are more involved and will raise the overall cost. Pocket installations are simpler and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're still trying to decide which type of installation you need, you can ask your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in LaSalle
EcoWatch differs from most reviewers, as we examine these companies through a sustainability lens. We have assessed the best window installers in LaSalle mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the LaSalle area so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you choose. 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 trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, warranty, professionalism, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
