How Installing Energy-Efficient Windows in Zachary Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to think about making the switch:
- Decrease your carbon footprint: In Zachary, you can cut your indirect greenhouse gas emissions by about 608 pounds per year when you upgrade to energy-efficient windows.
- Save money on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
- 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 because of their ability to filter out damaging UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way.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 Zachary
Windows come in varying purposes, shapes and styles, so costs and services will differ remarkably depending on your project. Below, we go over the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These figures are based on specific characteristics of your installation, including size, number of windows, material, type, the location of your home and more.
It’s also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your Zachary home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are typically 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 as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a window replacement is to figure out whether you need a full-frame or pocket installation.
A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations are simpler and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company should be able to help you figure out what’s best for your needs. In Zachary, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly 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 Zachary
EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Zachary and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
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 you opt for. 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 customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of installation, quality of parts, cost and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like 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 previously, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Zachary, LA Window Replacement FAQs
How much should window installation cost?
The typical cost of replacing a window can range between $450 and $650. There are many factors that influence the cost, which include the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows, your property’s location, the number of windows and local labor costs.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
Do you really have to use a window installation company?
You should use a window installation professional whenever you need new windows. Installing windows is a complicated process that can take a lot of time, so it’s best handled by the professionals.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
How long does window installation typically take?
Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
