How Installing Energy-Efficient Windows in Clinton Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could help you:

  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Clinton, that’s about 147 pounds per year on average.

Estimated Cost of Window Replacement in Clinton

Each window installation company offers various services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

Although the typical cost to replace one window is about $600, it can range from $200 to $1,200. But costs will vary significantly depending on the quality of your products, the current condition of your home, the number of windows you need and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your 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 a year when replacing single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies offer: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without taking out the entire frame, which is usually less expensive than a full-frame installation.

Your window installation company can advise you on the best type for your project. In Clinton, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Clinton

The EcoWatch Reviews team differs from most reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Clinton area so you can find a quality window installation company near you.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you choose. 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 most customers don’t have good feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. 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.

Clinton, CT Window Replacement FAQs

What is the average cost to install windows?

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

Which type of window should I get?

A window’s energy efficiency depends on a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

What do window installation companies do?

Window installers visit your home to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.

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. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
