How Installing Energy-Efficient Windows in Darien Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, including:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Darien, that's about 147 pounds per year on average.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save more on your bills.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Darien

Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the average costs and the primary services that you can find from window installation companies.

How Much Do New Windows Cost?

According to our market research, the typical cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. Costs will vary considerably based on the number of windows you need, your location, the current condition of your home and the quality of your products. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

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

How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the full window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're still debating which type of installation to get, you can talk to your provider and get their recommendation. 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 Darien

In our hunt to make your home improvements easier and more eco-friendly in Darien, EcoWatch landed on the above companies as the top window installation companies in the city. We've decided to evaluate the top window installers in Darien mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve Darien so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand 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 most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, professionalism, quality of parts, warranty, quality of installation and more.

Cost

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

Warranty

Protecting your investment in new windows is important. For that reason, 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 good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Darien, CT Window Replacement FAQs

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

The typical cost of installing one window ranges between $450 and $650. There are several factors that affect the price, such as styles and sizes of windows, how energy-efficient the windows are, the number of windows, your property's location, local labor costs and the materials used in designing the windows.

What are the kinds of windows?

The most common types of windows for homes are bay windows, transom windows, awning windows, casement windows, picture windows, double-hung and single-hung windows and slider windows.

What do window installation companies do?

Window installers cover the entire process — from replacing old windows with brand new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.

How long does window installation generally take?

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

When is it time to replace your windows?

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