How Installing Energy-Efficient Windows in Northbrook Saves You Money

When you switch to energy-efficient windows, you may see several benefits, including:

• Reduce your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged.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 energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save more on your bills.

Estimated Cost of Window Replacement in Northbrook

Each window installer offers varying services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

Generally, Northbrook homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at about $600. This is because the cost of window installations are based on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that affects the overall cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Northbrook

EcoWatch reviews differ from most reviews since we evaluate these companies through a sustainability lens. We’ve assessed the top window installers in Northbrook mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Northbrook, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Northbrook.

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 on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. 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.
