How Installing Energy-Efficient Windows in Slidell Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, including:
- Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Decrease your carbon footprint: By using less energy once you switch to Energy Star certified windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Slidell
When considering window installation, each company provides different services and costs. Let's look at some typical costs and services.
How Much Do New Windows Cost?
On average, homeowners in Slidell can anticipate that most window installations will cost between $250 and $1,200, with the average cost at about $600. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which have a higher price tag.
It's also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star predicts that upgrading the windows on your Slidell home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Another factor that affects the total cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because 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 thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
Your window replacement company should be able to help you decide what's best for your needs. In Slidell, the decision will mostly be based 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 evaluate your frames and window sills.

How We Choose the Best Window Installers in Slidell
In our search to make your home improvements easier and more eco-friendly in Slidell, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Slidell, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Slidell.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, cost, quality of installation, warranty, quality of parts 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 awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Slidell's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Slidell window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Slidell, LA Window Replacement FAQs
How much does window installation cost?
The average cost to replace a single window ranges between $450 and $650. There are a variety of factors that affect the price, such as local labor costs, your property's location, styles and sizes of windows, how energy-efficient the windows are, the number of windows and the materials used in designing the windows.
What are the most common types of replacement windows?
There are various kinds of windows you can get for your home, including transom windows, bay windows, double-hung and single-hung windows, slider windows, picture windows, casement windows and awning windows.
Can you install your own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. But if you don't have the time or know-how, we recommend hiring a professional.
How long does window installation take?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed during a typical 8-hour work day.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are usually 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.
