How Installing Energy-Efficient Windows in Fairfax Saves You Money

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

  • Better temperature control in your home: When you reside in a place like Fairfax where the winters can get very cold, you often need to depend on your heater to keep your home warm. Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Upgrading to energy-efficient windows can help decrease that number, which helps you save $451 a year on your bills.

Estimated Cost of Window Replacement in Fairfax

Each window replacement company offers varying services and has varying price points depending on several factors.

How Much Do New Windows Cost?

Generally, homeowners in Fairfax can anticipate that most window installations will cost between $250 and $1,200, with the average cost at around $600. But prices vary considerably based 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 add extra costs to your project.

Whether or not you want to install 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 $451 a year on your energy bills in Fairfax.

Asking for free quotes from multiple providers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

In regard to window installations, there are generally two kinds that your installer will have: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the trim, sill and frame. Pocket installations are on the simpler end and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Fairfax

EcoWatch reviews are different from other reviews since we're examining these companies through a sustainability lens. We have evaluated the top window replacement companies in Fairfax mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Fairfax, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Fairfax.

Work Quality

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

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of parts, professionalism, quality of installation, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to 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 considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Fairfax, CA Window Replacement FAQs

How much should a window install cost?

The average cost of replacing one window can range from $450 to $650. There are a variety of factors that affect the price, including the materials used in designing the windows, how energy-efficient the windows are, your property's location, styles and sizes of windows, local labor costs and the number of windows.

Which type of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll get 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.

What do window installers do?

Window installers go to your property to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

How long does window installation typically take?

Because the average installation time is 30 minutes per window, about 16 windows can be installed in a typical 8-hour work day.
