How Installing Energy-Efficient Windows in Mount Prospect Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could benefit you:

  • Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $295 a year on your bills.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Mount Prospect, that's about 449 pounds per year on average.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.

Estimated Cost of Window Replacement in Mount Prospect

Let's take a look at the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

On average, Mount Prospect homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. Costs will vary considerably based on the quality of your products, your location, the current condition of your home and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Mount Prospect homeowners $295+ each year after replacing single-pane windows.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

When considering window installations, in general there are two types that your installer will have: full-frame and pocket installations.

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations are simpler and won't carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're still trying to decide which type of installation to get, you can ask your installer and get their advice. The decision mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Mount Prospect

EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. We have assessed the best window installation companies in Mount Prospect primarily based on their energy efficient offerings, 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 takes the following factors into consideration:

Service Area

Since this is a guide for Mount Prospect, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Mount Prospect.

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. 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 customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, cost, professionalism, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a significant investment, so you'll want to be certain that investment is 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 been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
