How Installing Energy-Efficient Windows in Killingly Saves You Money

There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Save money on electricity bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll use less energy to heat or cool your house.
  • Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Killingly

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

How Much Do New Windows Cost?

On average, Killingly homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost varies depending on several factors, like material, type, number of windows, the location of your home, size and more.

It's important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Killingly homeowners $457+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step of a replacement is to think about whether you need a full-frame or pocket installation.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.

If you're not sure which kind of window installation service you should get, your installer can help you out. Generally, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Killingly

The EcoWatch Reviews team differs from other reviewers because we look at these companies through a sustainability lens. We have reviewed the best window installation companies in Killingly mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce 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 installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, cost, warranty, quality of parts, professionalism and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, 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. That's why window installation companies that provide lengthy warranties for products, parts and labor 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 experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Killingly, CT Window Replacement FAQs

What is the average cost to replace windows?

The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. 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 are the kinds of windows?

There are various kinds of windows you can get for your home, including casement windows, bay windows, awning windows, double-hung and single-hung windows, picture windows, transom windows and slider windows.

What do window installers do?

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

What time of year should I replace my windows?

Though you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, the weather should be dry, since rain can make the installation more difficult.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows at the same time is the only way to gain that benefit. However, if you have only one or two windows that are damaged or drafty, you can replace just those.
