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.

A review of the top window replacement companies in Concord may not seem like the most interesting article on the EcoWatch site, but trust us, windows impact your life more than you might think. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could make up around 30% of residential energy climate use. In Concord, where the energy bills are an average of $33 per month, that’s almost $$118 per year wasted.

That’s also bad news for the environment, as the additional energy used by drafty windows increases your carbon footprint.

We’ve made a list of the top installation companies to help you in your search, so you can not only take advantage of brand-new windows, but also save money on your electric bills.

How Installing Energy-Efficient Windows in Concord Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:

  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
  • 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  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Concord

Each window installation company provides varying services and has different prices depending on a few factors.

How Much Do New Windows Cost?

According to our market research, the national average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. But costs will differ considerably depending on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.

Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Asking for free quotes from multiple companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. A pocket installation involves replacing a window without taking out the complete frame, which is usually less expensive than a full-frame installation.

Your window replacement company will be able to help you figure out what’s best for your needs. In Concord, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Concord

EcoWatch reviews are different from most reviews since we look at these companies through a sustainability lens. We have reviewed the top window installation companies in Concord mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Concord, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Concord.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included on this list to make sure 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 online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, quality of installation, professionalism, cost, quality of parts and more.

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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