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

By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:

• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading 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 not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on energy bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
• Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.

Estimated Cost of Window Replacement in National City

Windows come in various styles, shapes and purposes, so costs and services will vary considerably based on several factors. Below, we describe the typical cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is because of the fact that window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Asking for free quotes from multiple providers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

The first step when considering a window replacement is to decide whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re unsure which window installation service you should get, your installer can advise you. Generally, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in National City

We’ve reviewed the best window installation companies in National City mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for National City, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in National City.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their service from a certain company, it won’t be featured on EcoWatch.

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 the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
