Best Window Installation & Replacement Companies

Energy Efficiency

A handful of windows manufactured by the Andersen corporation were awarded Energy Star’s “Most Efficient” in 2021, and Andersen was named Energy Star’s Partner of the Year in 2019.3 Not all of the company’s home windows are Energy Star certified, so be sure to mention that you want high-quality Energy Star windows when inquiring.

We admire that Renewal by Andersen has earned Green Seal’s approval for sustainability. (Green Seal is a nonprofit that reviews products and companies with rigorous standards for environmental impact.) According to the company’s website, Green Seal has estimated that if all windows were as efficient as Andersen windows, Americans would save up to 2.5% of annual energy consumption, or an estimated 200 gallons of oil per household.4

Many of Andersen’s windows are also approved by Scientific Certification Systems (SCS) Global Services — an organization that offers environmental, sustainability and quality certification to products around the world — for the amount of recycled materials they contain.5 The company claims to use 40% reclaimed wood fiber by weight during its wood-window manufacturing process.6

Renewal by Andersen: Pros

  • Select windows recognized as “Most Efficient” by Energy Star
  • Great industry reputation
  • Award-winning company
  • Member of the U.S. Green Building Council
  • Manufactures products in-house

Renewal by Andersen: Cons

  • Does not offer lifetime warranty
  • More expensive than competitors

Window World: Window Veteran

Window World is the largest window replacement company in the country, known for its vinyl windows and affordability as the “Home of the Original $189 Window.”7 Each Window World store is independently owned, which can be beneficial because it will feel more like dealing with a small business. That said, there may also be varying quality and services depending on your local Window World dealer.

As a company, Window World has many admirable qualities, like a foundation to support St. Jude Children’s Research Hospital and a military initiative to honor and serve America’s active military and veterans. It’s also certified for quality and safety by many reputable organizations, including the Environmental Protection Agency (EPA) and Energy Star.8

Estimated Costs & Services From Top Window Replacement Companies

Let’s take a look at the cost of window installation and the types of services you may need for your home.

Typical Window Installation Costs

best window installation companies quick tip

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. This is due to the fact that window installations are based on a variety of factors specific to your home, such as the size, type of material and number of windows you need to install, as well as the location of your property.

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 a year when replacing double-pane windows, clear glass windows.17 These savings vary depending on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary depending on the type of window material you choose. Wood windows are typically the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass compared to vinyl windows tend to be a bit more expensive, although they are not shown to be much more efficient.18

We recommend getting free quotes from multiple reputable window installation companies to find an installer that works best for your budget.

Window Installation Services

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

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: It’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation.

A pocket installation involves replacing a window within the existing frame. So, instead of tearing out the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which type of window installation service you need, your installer should be able to help you out. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How Did We Choose the Best Window Installers?

EcoWatch reviews differ from most websites, as we’re examining these companies through a sustainability lens. We’ve reviewed the best window installers primarily 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 lower energy 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 installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

Quality of Services

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Cost

As with most services, cheap window installers are not going to provide the most quality service, so this one is a give-and-take. Still, we want to make sure we’re highlighting window installation companies that offer a wide range of price and financing options so they’re accessible to most homeowners. Still, some companies on this list may be more expensive because they’ve got a reputation for high-quality services and products to back up their pricing.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Customer Satisfaction

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have nice things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
