How Installing Energy-Efficient Windows in Mansfield Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, such as:

• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Mansfield

Each window installer provides varying services and has varying costs depending on several factors.

How Much Do New Windows Cost?

Typically, homeowners in Mansfield can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. But costs differ remarkably 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 provide door installations, which have a higher price tag.

It’s important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Mansfield homeowners $461+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations entail replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has noticeable rot. Because these installations are more involved, they will increase the total cost. A pocket installation means replacing a window without removing the whole frame, which tends to be less expensive than a full-frame installation.

Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Mansfield

EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Mansfield and assigned rankings using the following methodology:

Service Area

Since this is a guide for Mansfield, we only included companies that cover the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Mansfield.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews 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 most other categories, including warranty, professionalism, cost, quality of parts, quality of installation 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 providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure 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

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