How Installing Energy-Efficient Windows in Largo Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 249 pounds per year on average.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Save money on energy bills: Once 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 house.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Largo
Windows come in different shapes and sizes, so costs and services will differ tremendously. 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 average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. These numbers are based on the specifics of your installation, like number of windows, type, the location of your home, size, material and more.
It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Largo home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We advise getting free quotes from several window installers to find the one that works best for you.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the overall 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 without replacing the 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.
If you’re not sure which window installation service you need, your installer should be able to advise you. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Largo
In our search to make your home improvements easier and more eco-friendly in Largo, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We’ve assessed the best window installation companies in Largo mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Largo, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Largo.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you opt for. We do give window installers higher marks 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, quality of installation, quality of parts, professionalism, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Largo’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Largo window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
