How Installing Energy-Efficient Windows in Marion Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Marion

When considering window installation, each company offers varying services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Even though the average cost to replace a single window is around $600, it can range anywhere from $200 to $1,200. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which carry a higher price tag.

It’s also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that switching out the windows on your Marion home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We advise getting free quotes from several window installers to find the one that works best for your budget.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the complete window, including the frame, trim and sill. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you choose what’s best for your needs. In Marion, the decision will mostly depend on how old your home is 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.

In our search to find the most reliable, eco-friendly window installers in Marion, EcoWatch assessed dozens of companies before landing on these. We’ve evaluated the best window installers in Marion mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Marion, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Marion.

Work Quality

When choosing new windows, the quality and variety of services can often play 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 patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, cost, quality of parts, warranty, professionalism and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want 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

Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
