How Installing Energy-Efficient Windows in Duncanville Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could benefit you:

  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 507 pounds.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: If you have an older 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 house if you decide to sell.

Estimated Cost of Window Replacement in Duncanville

Windows come in different purposes, styles and shapes, so costs and services will vary greatly based on your project. Below, we detail the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

On average, Duncanville homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at about $600. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which have a higher price tag.

Whether or not you choose energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $376 a year on your energy bills in Duncanville.

We recommend getting free quotes from several window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant deterioration. Because these installations are more involved, they will increase the total cost. A pocket installation involves installing a new window without replacing the frame. So, instead of tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Duncanville

EcoWatch reviews differ from other reviews since we’re examining these companies through a sustainability lens. We’ve decided to evaluate the best window installers in Duncanville primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded 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 well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Duncanville, TX Window Replacement FAQs

What is the average cost to replace windows?

The national average cost to install a window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often influenced by the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What kind of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.

Can you install your own windows?

Even though it is possible to install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

How often do you need to replace windows?

Windows typically last around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them checked by an expert to determine if they are in need of a repair or replacement.

Should I replace all my windows at once?

If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
