How Installing Energy-Efficient Windows in Greeley Saves You Money

When you switch to energy-efficient windows, you may see some perks, including:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save $457 a year on your bills.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Greeley, that’s about 460 pounds per year on average.

Estimated Cost of Window Replacement in Greeley

Windows come in all shapes and sizes, so costs and services will differ tremendously. Here are the average costs and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Typically, homeowners in Greeley can anticipate that most window installations will cost between $250 and $1,200, with the average cost at about $600. Costs will vary significantly depending on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $457 a year on your energy bills in Greeley.

Another factor that influences the total cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re still trying to decide which type of installation to get, you can ask your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Greeley

EcoWatch differs from other reviewers, as we assess these companies through a sustainability lens. We have assessed the top window replacement companies in Greeley primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Greeley so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have good feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a wide range 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Greeley, CO Window Replacement FAQs

How much does a window install cost?

The average cost of installing a single window ranges between $450 and $650. There are a variety of factors that influence the price, which include your property’s location, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, the number of windows and local labor costs.

What kind of window is the most energy-efficient?

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

What do window installation companies do?

Window installation professionals will do the entire process — from replacing your old windows with new ones to cleaning up afterward. In addition, a lot of companies offer window manufacturing, customization and repairs.

Should I replace my windows all at once?

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

How long does it take to install windows?

Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
