How Installing Energy-Efficient Windows in Costa Mesa 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 are the following:

• Save money on electricity bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Costa Mesa

When looking into window installation, each company provides different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Although the typical cost of replacing a single window is around $600, it can range anywhere from $200 to $1,200. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.

Whether or not you choose 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 $388 a year on your energy bills in Costa Mesa.

Another factor that affects the total cost is the material you choose for your frame. Aluminum frames are usually 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 offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a window replacement is to figure out whether you want a full-frame or pocket installation.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window within the existing frame. This means instead of removing the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Costa Mesa, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.
