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

Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Save money on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Oak Forest

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

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range from $200 to $1,200. Costs will differ considerably based on the current condition of your home, your location, the quality of your products and the number of windows you need. Many window companies also offer door installations and other add-ons like baths, shutters, coating and more. Additional services will increase your overall project costs.

Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

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

A full-frame installation replaces the complete window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the 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.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Oak Forest, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Oak Forest

In our hunt to find the most reliable, eco-friendly window installers in Oak Forest, the EcoWatch team examined many companies before deciding on these. We have reviewed the top window replacement companies in Oak Forest primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Oak Forest, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Oak Forest.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers higher marks 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 determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, quality of installation, cost, warranty, professionalism and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we gave higher points 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 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

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