How Installing Energy-Efficient Windows in Walnut Saves You Money

When you switch to energy-efficient windows, you may see some benefits, including:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Walnut

Each window replacement company offers varying services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

Typically, Walnut homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. How much it will cost depends on several factors, such as material, the location of your home, size, number of windows, type and more.

It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Walnut homeowners $509+ a year when replacing single-pane windows.

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid 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?

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

A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. This means instead of taking 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.

If you’re still trying to decide which kind of installation to get, you can consult with your installer and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Walnut

In our search to make your home improvements easier and more eco-friendly in Walnut, EcoWatch evaluated many companies before deciding on these. We’ve assessed the top window installation companies in Walnut primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

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 brand 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

Customer feedback is another super important review factor. If most customers don’t have good feedback about their experience with a certain window installation 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 want to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Walnut, CA Window Replacement FAQs

What is the average cost to install windows?

The national average cost of replacing one window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window should I get?

A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

You should hire a window installation company whenever you want new windows. Installing windows is a complicated process that can take a lot of time, so it’s best handled by the professionals.

How long does window installation generally take?

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