How Installing Energy-Efficient Windows in National City Saves You Money

There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help reduce that number, which helps you save some money on your bills.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In National City, that’s about 117 pounds per year on average.

Estimated Cost of Window Replacement in National City

Windows come in varying styles, purposes and shapes, so costs and services will differ considerably based on several factors. Below, we go over the typical cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Even though the national average cost to install a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, including number of windows, size, type, the location of your home, material and more.

It’s important to note that windows with higher 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 National City homeowners $491+ a year when replacing single-pane windows.

Something else that influences the total cost is the material of the frame you pick. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company should be able to help you decide what’s best for your needs. In National City, the decision will mostly depend on how old your home is and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in National City

In our hunt to find the most reliable, eco-friendly window installers in National City, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We’ve evaluated the top window replacement companies in National City mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, quality of parts, warranty, quality of installation, professionalism and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want 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

As discussed, windows are a considerable investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

National City, CA Window Replacement FAQs

What is the typical cost to install new windows?

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

What kind of window is the best for energy efficiency?

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

What do window installation companies do?

Window installers cover the entire process — from replacing old windows with new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.

How often should you replace your windows?

Windows generally have a lifespan of about 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?

Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
