How Installing Energy-Efficient Windows in Berkley Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could benefit you:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that number, which helps you save $375 a year on your bills.
  • Reduce your carbon footprint: In Berkley, you can lower your indirect greenhouse gas emissions by about 460 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Berkley

Windows come in various purposes, styles and shapes, so costs and services will vary remarkably based on several factors. Below, we describe the average cost and services that you can get from window installers.

How Much Do New Windows Cost?

According to our research, the national average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost you varies based on several factors, including size, the location of your home, number of windows, material, type and more.

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 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the entire window, including the sill, trim and frame. A pocket installation involves replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

If you're still debating which type of installation you need, you can consult with your installer and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Berkley

The EcoWatch Reviews team is different from most reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:

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

When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, warranty, professionalism, quality of installation, cost and more.

Cost

This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a significant investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) 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 earn higher rankings by our standards. We like to see at least ten years of experience.

Berkley, CO Window Replacement FAQs

What is the average cost to replace windows in a home?

The typical cost to install a window ranges between $450 and $650. There are a variety of factors that affect how much it costs, which include the number of windows, your property's location, local labor costs, the materials used in designing the windows, how energy-efficient the windows are and styles and sizes of windows.

What kind of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

Although you can install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

How often should you replace your windows?

Windows generally last around 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them looked at by an expert to see if they need any repairs or replacements.

Should I replace all my windows at once?
