How Installing Energy-Efficient Windows in Largo Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save money on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in Largo
Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, Largo homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost depends on several factors, including material, size, number of windows, the location of your home, type and more.
It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Largo homeowners $338+ a year when replacing single-pane windows.
Asking for free quotes from several companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket 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 still trying to decide which type of installation you should get, you can talk to your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Largo
EcoWatch differs from most reviewers because we look at these companies through a sustainability lens. We have decided to review the top window installers in Largo mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Largo area so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, cost, quality of parts, professionalism, warranty 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 the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Largo’s climate, homeowners will want to mitigate water damage, low efficiency and rot. 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.
