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

Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to think about making the switch:

• Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household 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.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
• Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
• 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.

Estimated Cost of Window Replacement in National City

Windows come in varying shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you'll find from the average window installation company.

How Much Do New Windows Cost?

Generally, homeowners in National City can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is because window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save National City homeowners $491+ per year after replacing single-pane windows.

Asking for free quotes from multiple installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window installation 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 damage. Wood can decay if not maintained properly over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in National City

EcoWatch reviews are different from most reviews because we assess these companies through a sustainability lens. We have evaluated the top window installation companies in National City mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for National City, we only included companies that serve the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in National City.

Work Quality

When it comes to 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 get. 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 patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, warranty, cost, quality of parts, quality of installation and more.

Cost

Cheaper windows certainly don't 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 points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

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