How Installing Energy-Efficient Windows in South Holland Saves You Money

There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
• Reduce your carbon footprint: In South Holland, you can reduce your indirect greenhouse gas emissions by about 449 pounds per year after you install energy-efficient windows.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in South Holland

Windows come in different styles, shapes and purposes, so costs and services will vary tremendously depending on several factors. Below, we describe the average cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

Typically, South Holland homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will make your project cost more.

Keep in mind that energy-efficient windows may have a higher price, 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 you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that influences the overall cost is the material you select for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer 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 and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step of a window replacement is to think about whether you want a full-frame or pocket installation.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window replacement company should be able to help you figure out what’s best for your needs. In South Holland, the decision will mostly be based on the age of your windows and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in South Holland

EcoWatch reviews differ from most reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in South Holland and ranked them using the following methodology:

Service Area

Because this is a guide for South Holland, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in South Holland.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in insulation 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 factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, professionalism, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a considerable investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
