How Installing Energy-Efficient Windows in Darien Saves You Money

Energy-efficient windows can provide benefits in more than one way. Here are a few reasons you may want to think about making the switch:

• Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll need less energy to heat or cool 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
• 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.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Darien, that's about 449 pounds per year on average.

Estimated Cost of Window Replacement in Darien

Let's go over the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. These figures vary based on the specifics of your installation, including number of windows, material, type, the location of your home, size and more.

It's important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Darien homeowners $300+ a year when replacing single-pane windows.

Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer 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 thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

Full-frame installations entail replacing the full window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has significant deterioration. Full-frame installations are more involved and will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to recommend the best type for your project. In Darien, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Darien

In our search to make your home improvements easier and more eco-friendly in Darien, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We have assessed the best window installation companies in Darien mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower energy 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 Darien, we paid more attention to companies that cover the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Darien.

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 type 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 patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, cost, quality of installation, warranty, quality of parts and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, 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 been in the industry for quite some time. Window installers 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.
