Meet the team


Simpson’s did a great job, they did everything promised, did it on time and on budget. The city inspector looked over their work and said ‘great job, Simpson’s always does great work, always meets code’.

From Bob S. on Yelp

We just had our new system put in this month. Once again, Simpson did a great job. John set up and designed a system and Jose was the lead installer. Both were a pleasure to work with, and they even finished ahead of schedule.

From John M. on Yelp

Hi I’d like to take the time to say how wonderful John and everyone at Simpson sheet metal have been to our family. We unexpectedly had to put a new heating system in due to a major illness in the family. John heard about the illness and had the heating system in and working within a week, at no extra cost.

From Carolyn T. on Yelp

When I called for a quote to replace my home heating unit, they were quick to respond with a site visit and analysis of our needs. Their price was absolutely the best while including everything we needed to replace our furnace and update our heating system. Their estimator, John was straight forward and helpful, suggesting only what we needed to meet our needs and current codes. They arrived as scheduled did a great job on the install and left the area in better condition than they found it.
