How Installing Energy-Efficient Windows in Windsor Saves You Money

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

  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Windsor, that’s about 460 pounds per year on average.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
  • Save money on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.

Estimated Cost of Window Replacement in Windsor

Each window replacement company offers varying services and has different prices depending on several factors.

How Much Do New Windows Cost?

Typically, Windsor homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost depends on several factors, such as the location of your home, size, type, material, number of windows and more.

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more initially, 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 Windsor homeowners $438+ 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 maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most 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 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. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window within the frame that’s already there. This means instead of taking out the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

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

How We Choose the Best Window Installers in Windsor

In our hunt to find the most reliable, eco-friendly window installers in Windsor, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed several window installers in Windsor and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Windsor, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Windsor.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, warranty, professionalism, cost and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Windsor, CO Window Replacement FAQs

How much should a window install cost?

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

What are the most common kinds of replacement windows?

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

What services do window installation companies do?

Window installation companies cover the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, a lot of companies offer window manufacturing, customization and repairs.

What time of year should I replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.

Should I replace my windows all at the same time?

If you’re upgrading your windows because of energy-efficiency, replacing all the windows at the same time is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or drafty, you can replace just those.
