How Installing Energy-Efficient Windows in Livermore Saves You Money

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

  • Decrease your carbon footprint: In Livermore, you can cut your indirect greenhouse gas emissions by about 117 pounds per year when you install energy-efficient windows.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.

Estimated Cost of Window Replacement in Livermore

Windows come in different purposes, shapes and styles, so costs and services will differ considerably based on your project. Below, we detail the average cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Generally, homeowners in Livermore can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. Costs will vary considerably depending on the number of windows you need, the quality of your products, the current condition of your home and your location. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.

Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $531 a year on your energy bills in Livermore.

Another factor that influences the overall cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when considering a window replacement is to clarify whether you need a full-frame or pocket installation.

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re still trying to decide which kind of installation you need, you can ask your provider and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Livermore

EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Livermore, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Livermore.

Work Quality

When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, cost, quality of parts, quality of installation, professionalism and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Livermore, CA Window Replacement FAQs

How much should a window install cost?

The national average cost of replacing one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is often influenced by the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What type of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

Can you replace your own windows?

If you’re handy and know how to replace a window, you may be able to install your own windows. But if you don’t have the time or skills, we recommend getting a professional to do it for you.

What time of year is a good time to replace my windows?

Although you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, the weather should be dry, since rain can make the installation harder.

When is it time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably 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.
