How Installing Energy-Efficient Windows in Greeley Saves You Money

When you upgrade to energy-efficient windows, you may see several perks, such as:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 460 pounds.
  • Better temperature control in your home: Living in a hot city like Greeley can often mean depending on your AC to keep your home cool. Energy-efficient windows can reduce the amount of cool air lost through your windows when cooling your home.
  • More efficient energy usage in your household: In Greeley where the winters can be very cold, energy-efficient windows cut back on how much heat is lost through your windows, which makes it easier to keep your home warm.

Estimated Cost of Window Replacement in Greeley

Each window installer offers varying services and has varying price points based on several factors.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. These amounts vary depending on specific characteristics of your installation, including the location of your home, number of windows, size, material, type and more.

It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that switching out the windows on your Greeley home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We advise requesting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

There are generally two types of window replacement services: full-frame and pocket installations.

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

Your window replacement company will be able to help you decide what's best for your needs. In Greeley, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Greeley

In our hunt to find the most reliable, eco-friendly window installers in Greeley, the EcoWatch team chose the above companies as the best window installation companies in the city. We've reviewed the top window installers in Greeley mainly based on their energy efficient offerings, 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 best window installation company near you.

Work Quality

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

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide 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 good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Greeley, CO Window Replacement FAQs

What is the average cost to replace windows?

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

What are the different types of windows?

There are several different types of windows you can get for your home, including bay windows, picture windows, awning windows, casement windows, slider windows, double-hung and single-hung windows and transom windows.

What services do window installation companies provide?

Window installation professionals visit your home to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.

Should I replace all my windows at once?

If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
