How Installing Energy-Efficient Windows in Fairfield Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, including:

• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 147 pounds per year on average.
• Save on power bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $441 annually on your energy bills in Fairfield.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Fairfield

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

How Much Do New Windows Cost?

Generally, homeowners in Fairfield can expect that most window installations will range from $250 to $1,200, with the average cost at around $600. This is because of the fact that the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

It’s also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Fairfield 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 installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

When considering window replacements, there are typically two kinds that your provider will have: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame. So, instead of tearing out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

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

How We Choose the Best Window Installers in Fairfield

In our hunt to make your home improvements easier and more eco-friendly in Fairfield, the EcoWatch team evaluated dozens of companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

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

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have good feedback about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a variety 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

Lastly, we like to see companies that have a proven 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.
