How Installing Energy-Efficient Windows in St. Augustine Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, including:

• Save on electricity bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your home.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• 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 due to their ability to filter out harmful UV rays.
• Protect your investment: If your home is on the older side, 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 house if you decide to sell.

Estimated Cost of Window Replacement in St. Augustine

When looking into window installation, each company offers different services and prices. Let’s look at some average costs and services.

How Much Do New Windows Cost?

Although the average cost of replacing one window is around $600, it can range anywhere from $200 to $1,200. These numbers vary depending on specific characteristics of your installation, such as type, the location of your home, size, material, number of windows and more.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two kinds that your installer will offer: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around 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 simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re unsure which kind of window installation service you should get, your installer can help you out. Typically, the choice 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 St. Augustine

EcoWatch reviews differ from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:

Service Area

Since this is a guide for St. Augustine, we only included companies that provide services to 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 St. Augustine.

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have good feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try 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, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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 good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
