How Installing Energy-Efficient Windows in McHenry Saves You Money

Upgrading to energy-efficient windows can 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:

• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Save on power bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
• Decrease your carbon footprint: In McHenry, you can cut your indirect greenhouse gas emissions by about 449 pounds per year after you switch to energy-efficient windows.

Estimated Cost of Window Replacement in McHenry

Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the average costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

Generally, McHenry 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 number of windows you need and the current condition of your home. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save McHenry homeowners $317+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step when planning a window replacement is to decide whether you need a full-frame or pocket installation.

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation involves replacing a window without taking out the complete frame, which is usually cheaper than a full-frame installation.

If you’re still trying to decide which type of installation you need, you can talk to your installer and get their advice. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in McHenry

In our hunt to make your home improvements easier and more eco-friendly in McHenry, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed several window installers in McHenry and assigned rankings using the following methodology:

Service Area

Since this is a guide for McHenry, we paid more attention to companies that provide services to 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 McHenry.

Work Quality

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

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, cost, quality of parts, warranty and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like 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 previously, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of McHenry’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of McHenry window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
