More About Us

Kollmar Sheet Metal, Inc was founded in 1927. The company began as a small, close-knit operation and has remained so to this day. Our customers tell us they enjoy seeing the same faces, year after year, each time they work with us.

Over the years, we have expanded our services to fabricating and installing most anything made out of any kind of metal. Since we are a custom metal fabrication shop, we get sometimes get interesting or unusual requests, which have resulted in wonderful opportunities to showcase our talents in the metal working trade.

In 2007, after eight decades at our downtown location, we moved our operations to our expanded South Seattle shop which allows us to take on larger projects.

We employ only skilled technicians whom have completed a five-year certification program. This provides our clients the extra comfort of knowing that experienced and well-trained technicians are on the job.

Our estimator has over 30 years of “hands on” fabrication and installation experience. He is highly regarded in the metalworking industry and especially valued by our clients for his vast array of knowledge in the trade. Our clients have come to depend on his advice and expertise to get their stainless steel duct cover and other projects completed correctly, and so can you!

All of us at Kollmar take great pride in our products and providing top notch customer service and satisfaction.
