How Installing Energy-Efficient Windows in Gretna Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to make the switch:

• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
• Save money on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Gretna

Windows come in various shapes and sizes, so costs and services will vary greatly. Here are the typical costs and the primary services that you’ll find from window installers.

How Much Do New Windows Cost?

Although the national average cost of replacing a single window is about $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, including the location of your home, material, type, number of windows, size and more.

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

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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 provide decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has significant deterioration. Because these installations are more involved, they will increase overall costs. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

Your window replacement company should be able to help you decide what’s best for your needs. In Gretna, the decision will mostly depend on the age of your home and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Gretna

The EcoWatch Reviews team differs from most reviewers since we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Gretna and ranked them using the following methodology:

Service Area

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

Work Quality

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

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, professionalism, quality of parts, warranty, quality of installation and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a hefty investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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