Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although renewable energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house’s energy efficiency can also have a big impact on home energy conservation. Potential leaks or drafts can reduce your home’s energy efficiency by up to 30%, according to the Department of Energy. In Clinton, that’s about $403 per year that you could save on your power bills after making the switch.

Installing upgraded, efficient windows on your house can help you save money each month on your electric bills — and you can help the environment as well.

Unlike other sites, EcoWatch ranks window companies based on energy efficiency while also factoring in cost, customer satisfaction and service area.

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  • Protect your investment: When you have an older home, your windows could also be outdated or leaky.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. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.

Keep in mind that energy-efficient windows may come at a higher price tag, 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 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Asking for free quotes from several installers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations are on the simpler end and won’t cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

Your window installation company should be able to help you understand what’s best for your needs. In Clinton, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Clinton

The EcoWatch Reviews team differs from most reviewers since we’re examining these companies through a sustainability lens. We’ve evaluated the best window installation companies in Clinton primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Clinton, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Clinton.

Work Quality

When picking new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, cost, quality of installation, professionalism, warranty and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try 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. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Clinton’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Clinton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Clinton, CT Window Replacement FAQs

How much should window installation cost?

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

What kind of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.

What do window installation companies do?

Window installation companies 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 do you know it’s time to replace your windows?

Windows generally have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have an expert take a look at them to see if they need any repairs or replacements.
