How Installing Energy-Efficient Windows in Firestone Saves You Money

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

  • Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
  • Save on power bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save around $457 annually on your energy bills in Firestone.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Firestone

Windows come in different shapes and sizes, so costs and services will differ tremendously. Here are the typical costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200. These numbers vary depending on specific characteristics of your installation, like size, the location of your home, type, number of windows, material and more.

Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $457 a year on your energy bills in Firestone.

Asking for free quotes from multiple providers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want a new style or your window has significant rot. With this service, your installers will replace the complete window, including the frame, sill and trim. A pocket installation entails installing a new window without replacing the frame. So, instead of taking out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Firestone, the decision 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 Firestone

In our search to find the most reliable, eco-friendly window installers in Firestone, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Firestone and ranked them based on the following methodology:

Service Area

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

Work Quality

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

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including cost, warranty, quality of installation, professionalism, quality of parts and more.

Cost

This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer 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. 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 installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Firestone, CO Window Replacement FAQs

How much should a window install cost?

The national average cost of replacing one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the most common kinds of replacement windows?

The most common types of windows for homes include: double-hung and single-hung windows, slider windows, bay windows, awning windows, casement windows, picture 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 providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn’t be raining, as rain can make the installation harder.

When is it time to replace your windows?

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