About Us

About Us

Family Owned and Operated Since 1990.

A message from the Founder:
My wife Sheila and I started Chimney Clean Company in San Jose, CA, in 1990. I was a Mechanical Engineer working for a large high tech company, at the time. We decided that there was a tremendous demand for chimney and other home services in our area, started our own company, and never looked back!

As a licensed state masonry contractor, I value ethical, quality work above all else. We are members of the Golden State Chimney Sweep Guild. Not only have I undergone hundreds of hours of training under the top Chimney Sweeps and Technicians in the country, but I also ensure each of our technicians undergo a rigorous apprenticeship program as part of their on-the-job training.

I partnered with Dan Maas in 2018 as part of an overall plan to service more customers in our valley. Dan Maas comes from a life-long background of installing high-end wood floors to perfection and he has adapted to the Chimney Sweep and Dryer Duct world with great aplomb. His wife Jennifer Maas, has been a business manager for the better part of 30 years and she handles the marketing, scheduling and administration for the office.

We train our employees with our own intensive in-house training program. Current technicians, Nathan & Luis, have been trained to deliver top quality service to every customer. I’m proud of our team and happy we can reach and help more customers with their Chimney and Dryer Duct needs.
