How Installing Energy-Efficient Windows in LaSalle Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:

• Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Save money on electricity bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $308 annually on your energy bills in LaSalle.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in LaSalle

Let’s go over the cost of updating your windows and the types of services you may need for your home.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These estimates vary depending on the specifics of your installation, including material, size, number of windows, type, the location of your home and more.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Another factor that influences the total cost is the material you pick for your frame. Aluminum frames are usually the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, 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 replacement services: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your professionals will replace the full window, including the frame, trim and sill. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you decide which type of installation you need.

We’ve reviewed the best window installation companies in LaSalle mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback 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 nearly every category, including professionalism, warranty, cost, quality of installation, quality of parts and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we gave 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 provide 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 been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
