About Dan the Window Man

Since 1981 We’ve Been

Saving You Money & Maximizing Comfort

We began in 1981, with the observation that Denver was built early to mid century, and mostly without energy efficiency in mind.  As a consumer, I felt the pinch right away, living in a very inefficient house with high energy bills,  so very quickly we made it our motto “Affordable Solutions to Save Energy”, as most homeowners needed to save money on their energy bills AND make the house more comfortable. 

In our 40 year track record, we find that even recently built homes have just the basic windows put in them as the builders want to keep costs down, but these windows are poor performers and do not last many years.  We have our work cut out for us, as there are still thousands of homes that need more comfort and savings, not to mention the many new features that windows and doors offer today.  

We continue to be a great source for identifying needs in older windows and old installation methods that need upgrades and improvements to bring  up to code and higher performance.  We have a passion for energy saving, renewable energy, conservation, and sustainability.

What Keeps Us Going?

The Mission

A home is a haven, and should be protected from the cold and heat, and contents protected from sun, wind, and harsh weather.  There are many comforts we can buy, but our home, best kept, can warm our hearts.


That’s why we at Dan the Window Man make every effort to provide the families of our community a choice of window brands that:

  • are professionally installed and serviced
  • are affordably priced
  • give our customers value for their dollar
  • are the perfect fit for their home

We make homes more comfortable, and homeowners more satisfied!

We Are

More Than “Window Sales Guys”

Having a degree in plastics design and process, I have been interested and following closely the development of vinyl and composite materials for manufacturing windows, as they are more insulating.

We are always looking for best engineering and design of these frames and the glass packages that go in them.  As students of the industry, we are on the lookout and ready to promote the highest-quality advancements coming out from our labs and company factories to keep your home healthy.

Dan Ryan

Founder, Owner

Growing up around the jobsites and in the sales meetins, I have learned by example and through the field training I got while helping in all facets of the business.  In addition, I learned business and industry best practices in the local chamber of commerce schools for young business owners.

I’ve also learned a ton over the years, as I’ve fostered fruitful relationships with our manufacturers, who have provided ample training, information, and more to support our customers.

Satisfied Customers

Dan and Sheridan replaced all the windows in my house, the sliding glass door, and the front door, at a very reasonable price. When we later had problems, Sheridan was on the ball and didn't give up until it was fixed. The installers were great as well, and we're very happy with our new doors and window.

The best experience I could have hoped for. The price was VERY competitive and the craftsmen who did the work were top notch. I will definitely be using Dan’s company for upcoming window replacements.

Dan installed new windows in my 1895 Victorian house and what a difference they made! They actually open and close (I know, this is basic, but if you have older windows, you get this), they are easy to clean and our home is so much quieter now. The curtains don't rustle and the windows don't rattle when the wind blows. The furnace is not running as much. I could go on and on. Dan's prices were well below the other bids I got. I like that he doesn't try to upsell you. He offers good, better and best and let's you decide. He also offers many brands to choose from. He put a lot of energy into making sure I was happy. I give him two thumbs up!

Wheat Ridge

Dan, Sheridan and their installers are top notch. We had lots of questions and Dan was patient, informative and helpful. He met with us several times while we decided what to do. We ended up replacing windows in our entire house. The windows are great. The whole process was seamless. The installers were organized, professional and hard working. They did a great job and cleaned up after themselves as they went. You can't ask for a better window replacement company. They earn my highest recommendation.
