How Installing Energy-Efficient Windows in Cornelius Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:

• Save on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Cornelius, that’s about 271 pounds per year on average.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
• Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Cornelius

Let’s go over the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Generally, homeowners in Cornelius can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. These estimates vary depending on the specifics of your installation, like number of windows, the location of your home, type, size, material and more.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install 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.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first step of a window installation is to clarify whether you need a full-frame or pocket installation.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Cornelius, the decision 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 Cornelius

In our search to find the most reliable, eco-friendly window installers in Cornelius, the EcoWatch Reviews team assessed many companies before deciding on these. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

Because this is a guide for Cornelius, 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 Cornelius.

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 on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installers won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is protected. Window installation companies that provide 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 quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
