How Installing Energy-Efficient Windows in Castaic Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:

• Protect your investment: The older your home is, the more likely it is that getting new 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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 property if you decide to sell.

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% because you need less energy.

Estimated Cost of Window Replacement in Castaic

Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the typical cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. Costs will vary significantly depending on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.

It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your Castaic home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Another factor that influences the total cost is the material of the frame you pick. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer 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 as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers 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 more simple and affordable. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

If you’re still trying to decide which type of installation you need, you can talk to your installer and get their advice. The choice mostly depends on how old the frames are and if there’s any damage.
