How Installing Energy-Efficient Windows in Boulder Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 460 pounds per year on average.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Save money on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $376 annually on your energy bills in Boulder.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Boulder
Windows come in varying styles, shapes and purposes, so costs and services will vary tremendously depending on your project. Below, we go over the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost depends on several factors, such as the location of your home, material, size, number of windows, type and more.
It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Boulder homeowners $376+ a year when replacing single-pane windows.
We recommend getting free quotes from several window installation companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has noticeable rot or deterioration. Full-frame installations are more involved and will increase the overall cost. Pocket installations are simpler 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 may have to get a full-frame installation instead.
Your window installation company will be able to help you choose what's best for your needs. In Boulder, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Boulder
EcoWatch reviews are different from most reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them 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 the right window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services can often play 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 customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of parts, cost, warranty, quality of installation and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with 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 installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Boulder, CO Window Replacement FAQs
What is the average cost to install windows?
The national average cost to replace a window is about $600 but can range between $200 and $1,200, based 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, remember 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: picture windows, awning windows, bay windows, transom windows, double-hung and single-hung windows, casement windows and slider windows.
Can I replace my own windows?
Although you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How often do you need to replace your windows?
Windows usually last 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to see if they need any repairs or replacements.
Should I replace my windows all 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 only a few windows that are broken or drafty, you can replace just those.
