How Installing Energy-Efficient Windows in Cos Cob Saves You Money

There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.

Estimated Cost of Window Replacement in Cos Cob

Each window replacement company provides various services and has different price points based on several factors.

How Much Do New Windows Cost?

Though the average of installing one window is about $600, it can range anywhere from $200 to $1,200. Costs will differ significantly depending on the number of windows you need, the current condition of your home, the quality of your products and your location. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Cos Cob homeowners $459+ a year after replacing single-pane windows.

Costs will also vary based on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable deterioration. Full-frame installations are more involved and will raise overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window replacement company should be able to help you decide what's best for your needs. In Cos Cob, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Cos Cob

EcoWatch is different from most reviewers, as we assess these companies through a sustainability lens. We've evaluated the top window replacement companies in Cos Cob 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 have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

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

Work Quality

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

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of installation, quality of parts, professionalism, warranty 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 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 provide 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 experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Cos Cob, CT Window Replacement FAQs

How much should a window install cost?

The national average cost of installing a window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window is the best?

A window's energy efficiency is influenced by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Do I really need to use a window installation company?

You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best left to the professionals.

How long does it generally take to install windows?

Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.

Should I replace all my windows at once?

If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
