How Installing Energy-Efficient Windows in Paramount Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Better temperature control in your home: Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Paramount

Windows come in various styles, shapes and purposes, so costs and services will differ greatly depending on your project. Below, we detail the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Generally, Paramount homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. Costs will differ significantly based on the number of windows you need, your location, the quality of your products and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

When it comes to window installations, in general there are two types that your provider will offer: full-frame and pocket installations.

Full-frame installations involve replacing the full 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 damage. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation entails replacing a window without taking out the whole frame, which is generally less expensive than a full-frame installation.

If you're still trying to decide which type of installation you need, you can ask your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Paramount

EcoWatch reviews are different from most reviews, as we examine these companies through a sustainability lens. We have decided to evaluate the best window installation companies in Paramount mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Paramount so you can find the right window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers won't always provide the most quality service. Still, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a significant investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Paramount's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Paramount window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Paramount, CA Window Replacement FAQs

What is the typical cost to install new windows in a home?

The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What type of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

When do I have to use a window installation company?

You should hire a window installation professional whenever you want new windows. Installing windows is a complicated process that can take a lot of time, so it's best handled by the professionals.

How often do you need to replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.

Should I replace all my windows at once?

If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
