How Installing Energy-Efficient Windows in Commerce City Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could help you:

  • 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.
  • Save money on energy bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $453 annually on your energy bills in Commerce City.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Commerce City

When researching window installation, each company provides varying services and prices. Let's look at some average costs and services.

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 replacement costs can range from $200 to $1,200 a window. This is due to the fact that window installations depend on a variety of factors specific to your home, like the size, 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 come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material of the frame you pick. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because 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?

In regard to window installations, in general there are two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations are simpler and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Commerce City, the choice will mostly depend on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Commerce City

In our search to find the most reliable, eco-friendly window installers in Commerce City, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed several window installers in Commerce City and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Commerce City so you can find a quality window installation company near you.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer on this list to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. Still, we want to ensure 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. That's why 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 been in the industry for quite some time. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Commerce City, CO Window Replacement FAQs

What is the average cost to replace windows?

The average cost to install one window can range between $450 and $650. There are several factors that affect how much it costs, including the materials used in designing the windows, local labor costs, styles and sizes of windows, your property's location, the number of windows and how energy-efficient the windows are.

What type of window is the best for energy efficiency?

A window's energy efficiency is affected by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Can I install my own windows?

If you're handy and have experience with installing a replacement window, you may be able to install your own windows. But if you don't have the time or know-how, we recommend hiring a professional.

What time of year should I replace my windows?

Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.

How often should you replace windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
