How Installing Energy-Efficient Windows in Milliken Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, such as:

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save $388 a year on your bills.
  • 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.
  • Reduce your carbon footprint: In Milliken, you can cut your indirect greenhouse gas emissions by about 460 pounds per year when you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Milliken

Windows come in varying shapes, purposes and styles, so costs and services will differ greatly depending on your project. Below, we describe the typical cost and services that you'll find from window installers.

How Much Do New Windows Cost?

On average, homeowners in Milliken can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will make your project cost more.

It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Milliken homeowners $388+ a year when replacing single-pane windows.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step of a replacement is to clarify whether you want a full-frame or pocket installation.

A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Milliken, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Milliken

In our search to make your home improvements easier and more eco-friendly in Milliken, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer 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 a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer included on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that offer a spectrum 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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Milliken, CO Window Replacement FAQs

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

The national average cost of replacing a window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the most common types of replacement windows?

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

What services do window installation companies provide?

Window installers go to your house to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

How long does window installation generally take?

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

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on energy costs, replacing all the windows together is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or leaky, you can replace just those.
