How Installing Energy-Efficient Windows in Golden Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could benefit you:

  • Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Save money on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
  • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Golden

When considering window installation, each company provides varying services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

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

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Golden homeowners $443+ a year after replacing single-pane windows.

Costs will also vary based on the material you want for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and offer 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?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re still debating which type of installation you should get, you can ask your provider and get their advice. The choice mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Golden

In our hunt to make your home improvements easier and more eco-friendly in Golden, the EcoWatch Reviews team evaluated many companies before deciding on these. Along with energy efficiency, we assessed several window installers in Golden and assigned rankings using the following methodology:

Service Area

Since this is a guide for Golden, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Golden.

Work Quality

When choosing new windows, the quality and breadth 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 factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good things to say 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 companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.

You should use a window installation company whenever you want to replace your windows. Installing windows is a involved process that can take a lot of time, so it’s best handled by the professionals.

What time of year should I replace my windows?

Replacement windows can be installed at any time, but warmer weather is typically better.

Most importantly, the weather should be dry.
