How Installing Energy-Efficient Windows in Biloxi Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could benefit you:

• Save money on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save some money on your bills.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Biloxi, that’s about 600 pounds per year on average.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Biloxi

Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

According to our market research, the national average cost to replace a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. Costs will vary significantly depending on your location, the current condition of your home, the number of windows you need and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Biloxi homeowners $315+ per year after replacing single-pane windows.

The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

There are typically two kinds of window installation services: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation entails installing a new window within the old frame. So, instead of tearing out the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to recommend the best type for your project. In Biloxi, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Biloxi

EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Biloxi area so you can find the best window installation company near you.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. 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

Customer feedback is another very important review factor. If most customers don’t have good things to say about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a significant investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Biloxi’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Biloxi window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
