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.

Whether you're doing home renovations or have windows that need repairs, windows play a key role in conserving your home's energy. If your windows are outdated or damaged, you could be sending 25-30% of your house's heat or cool air out of them.

That's also bad news for the environment because the additional energy used by leaky windows increases your carbon footprint.

Unlike other review sites, EcoWatch ranks window installation companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Columbia Saves You Money

When you switch to energy-efficient windows, you may see several benefits, including:

  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Columbia, that's about 147 pounds per year on average.

Estimated Cost of Window Replacement in Columbia

Let's go over the cost of updating your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

On average, homeowners in Columbia can anticipate that most window installations will cost between $250 and $1,200, with the average cost sitting at around $600. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will add extra costs to your project.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Something else that affects the total cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation involves replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Columbia

In our hunt to make your home improvements easier and more eco-friendly in Columbia, EcoWatch examined dozens of companies before landing on these. We have reviewed the best window installation companies in Columbia mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Columbia so you can find the right window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain installer, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won't always provide the most quality service. Still, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies 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.

Columbia, CT Window Replacement FAQs

What is the typical cost to install new windows?

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

What type 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're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

Can you install your own windows?

If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend getting a professional to do it for you.

How long does it take to install windows?

Since the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
