Lockhart Window Cost Calculator

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Lockhart Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could benefit you:

  • 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.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Reduce your carbon footprint: In Lockhart, you can lower your indirect greenhouse gas emissions by about 507 pounds per year when you switch to energy-efficient windows.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.

Estimated Cost of Window Replacement in Lockhart

Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the national average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. But prices vary 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 will add extra costs to your project.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lockhart homeowners $392+ per year after replacing single-pane windows.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. These installations are more involved and will increase overall costs. A pocket installation involves replacing a window within the old frame. This means instead of tearing out the whole unit 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 can help you decide which type of installation you need.

How We Choose the Best Window Installers in Lockhart

The EcoWatch Reviews team differs from most reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Lockhart and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Lockhart so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company 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

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Lockhart, TX Window Replacement FAQs

What is the average cost to install new windows?

The typical cost of installing a single window can range from $450 to $650. There are several factors that influence the price, such as your property’s location, the materials used in designing the windows, how energy-efficient the windows are, the number of windows, styles and sizes of windows and local labor costs.

Which type of window is the best?

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

Can I replace my own windows?

While it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.

When is it time to replace your windows?

Windows generally have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have them looked at by an expert to see if they need any repairs or replacements.

How long does it generally take to install windows?

Because the average installation time is 30 minutes per window, around 16 windows can be installed in a typical 8-hour work day.
