How Installing Energy-Efficient Windows in East Whittier Saves You Money

When you upgrade to energy-efficient windows, you may see several perks, such as:

• Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient windows can help lower that amount, which helps you save $509 a year on your bills.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in East Whittier

Let’s go over the cost of updating your windows and the types of services offered by installers.

How Much Do New Windows Cost?

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

It’s also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your East Whittier home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Something else that influences the total cost is the material of the frame you choose. Aluminum frames are generally 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, as 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?

The first step of a window replacement is to figure out whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the complete window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage. These installations are more involved and will increase the total cost. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you’re still debating which type of installation to get, you can talk to your provider and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage present.

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the East Whittier area so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including warranty, quality of parts, professionalism, cost, quality of installation and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of East Whittier’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of East Whittier window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
