How Installing Energy-Efficient Windows in Flagstaff Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:

  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • More efficient energy use in your home: Because the summers can get quite hot in Flagstaff, homeowners usually rely on their air conditioner during that time. Energy-efficient windows decrease how much cool air is lost through your windows, which makes it easier to keep your house cool.
  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Flagstaff

Let's go over the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. These numbers vary depending on the specifics of your installation, such as the location of your home, size, type, number of windows, material and more.

It's important to bear in mind 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 Flagstaff homeowners $412+ a year when replacing single-pane windows.

Getting 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?

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

Full-frame installations require replacing the full 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 significant deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

Your window replacement company should be able to help you choose what's best for your needs. In Flagstaff, the decision will mostly be based 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 good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Flagstaff

In our hunt to find the most reliable, eco-friendly window installers in Flagstaff, the EcoWatch team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Flagstaff and ranked them based on the following methodology:

Service Area

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

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company in our guide to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If most customers don't have positive things to say about their service from a certain window installation company, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with 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.

Flagstaff, AZ Window Replacement FAQs

How much does a window install cost?

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

The most common kinds of windows for homes include: double-hung and single-hung windows, bay windows, transom windows, casement windows, awning windows, slider windows and picture windows.

Can I install my own windows?

While you can install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

Should I replace all my windows at once?

If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
