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

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

• Decrease your carbon footprint: By using less energy after you switch to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save $509 a year on your bills.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in San Fernando

Windows come in various styles, shapes and purposes, so costs and services will vary considerably depending on several factors. Below, we detail the average cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

Though the typical cost to install a single window is around $600, it can range from $200 to $1,200. These figures vary based on specific characteristics of your installation, such as material, number of windows, the location of your home, type, size and more.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in San Fernando.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

When considering window replacements, there are typically two types that your provider will have: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different 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 (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In San Fernando, the decision will mostly be based on the efficiency of your home and how old your existing frames are.
