How Installing Energy-Efficient Windows in New London Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to consider making the switch:

  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
  • Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in New London

Windows come in various styles, purposes and shapes, so costs and services will vary greatly based on your project. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

On average, New London homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. This is due to the fact that the cost of window installations are based 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.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save New London homeowners $424+ each year after replacing single-pane windows.

Another factor that affects the overall cost is the material of the frame you choose. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two types of window installation services companies provide: full-frame and pocket installations.

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation involves installing a new window within the existing frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which type of installation to get, you can talk to your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in New London

In our hunt to make your home improvements easier and more eco-friendly in New London, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We’ve reviewed the best window installers in New London mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your 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 installers that serve New London so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you get. 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

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their experience with a certain installer, it won’t be featured on EcoWatch.

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 points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that have 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 installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

New London, CT Window Replacement FAQs

How much does a window install cost?

The national average cost to replace one window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which type 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 typically the most energy-efficient and are certified by the U.S. Department of Energy.

What services do window installation companies offer?

Window installation professionals will do the entire process — from replacing old windows with brand-new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.

How often should you replace 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. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, it’s probably time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
