How Installing Energy-Efficient Windows in San Clemente Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, such as:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• 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 on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in San Clemente

Windows come in varying shapes, purposes and styles, so costs and services will vary tremendously 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?

The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $388 a year on your energy bills in San Clemente.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, but 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 more efficient.

What Services do Window Installers Offer?

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

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. A pocket installation involves replacing a window without taking out the complete frame, which is usually less expensive than a full-frame installation.

Your window installation company will be able to help you decide what’s best for your needs. In San Clemente, the decision will mostly depend on the age of your home and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional assess your frames and window sills.
