How Installing Energy-Efficient Windows in South El Monte Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
• Reduce your carbon footprint: Reducing how much 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 South El Monte

Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the typical costs and the primary services that you’ll find from window installation companies.

How Much Do New Windows Cost?

On average, South El Monte homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at around $600. This is because of the fact that window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save South El Monte homeowners $509+ a year when replacing single-pane windows.

Something else that influences the total cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide 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?

In general, there are two types of window installation services companies offer: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of deterioration. With this service, your professionals will replace the whole window, including the sill, frame and trim. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company will be able to advise you on the best type for your project. In South El Monte, the decision will mostly be based on the efficiency of your home and how old your existing frames are.
