How Installing Energy-Efficient Windows in Slidell Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Slidell, that’s about 608 pounds per year on average.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Slidell
Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. These figures vary depending on specific characteristics of your installation, like type, number of windows, size, material, the location of your home and more.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $273 a year on your energy bills in Slidell.
Another factor that affects the total cost is the material of the frame you choose. 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 are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. 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 will be able to help you choose what’s best for your needs. In Slidell, 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 assess your frames and window sills.

How We Choose the Best Window Installers in Slidell
The EcoWatch Reviews team is different from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Slidell and ranked them using the following methodology:
Service Area
Because this is a guide for Slidell, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Slidell.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of parts, quality of installation, professionalism, warranty 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 the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, 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 installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
