A guide on the best window replacement companies in Lake Forest may not seem like the most interesting article on the EcoWatch site, but trust us, windows have more of an impact on your life than you might think. Drafty, leaky windows can cost you in power bills. In fact, the Department of Energy estimates that 25-30% of your home’s heat or cool air could be lost through your windows.

That’s also bad news for the environment because the extra energy used by drafty windows increases your carbon footprint.

      How Installing Energy-Efficient Windows in Lake Forest Saves You Money

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

      • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
      • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Lake Forest, that’s about 449 pounds per year on average.
      • Save on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
      • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

      Estimated Cost of Window Replacement in Lake Forest

      Windows come in various shapes, purposes and styles, so costs and services will vary tremendously depending on several factors. Below, we go over the typical cost and services that you’ll find from window installation companies.

      How Much Do New Windows Cost?

      The average cost to replace a single window is about $600 but can range from $200 to $1,200. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.

      It’s important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Lake Forest homeowners $298+ a year when replacing single-pane windows.

      Something else that affects the total cost is the material of the frame you select. Aluminum frames are generally 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 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?

      In regard to window installations, there are typically two kinds that your provider will offer: full-frame and pocket installations.

      Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

      Your window installation company can recommend the best type for your project. In Lake Forest, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

      How We Choose the Best Window Installers in Lake Forest

      EcoWatch reviews are different from other reviews, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

      Service Area

      This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Lake Forest area so you can find a quality window installation company near you.

      Work Quality

      We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

      Customer Reviews

      Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain company, you won’t see it featured on EcoWatch.

      Cost

      Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when 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 sizable investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

      Years of Experience

      Because of Lake Forest’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Lake Forest window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

      Lake Forest, IL Window Replacement FAQs

      How much does a window install cost?

      The national average cost of installing one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

      What are the most common types of replacement windows?

      There are several different types of windows you can get for your house, including picture windows, casement windows, transom windows, slider windows, bay windows, double-hung and single-hung windows and awning windows.

      Do you really need to use a window installation company?

      You should use a window installation professional whenever you need new windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best left to the professionals.

      When is the best time of year to replace windows?

      Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

      Should I replace my windows all at once?

      If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
