CUSTOM DUCT WORK AND SHEET METAL FABRICATION
With the expansion of our sheet metal shop, the company purchased a new duct bending machine in early 2009. This machine allows us to fabricate our own duct work.
We fabricate our own standard, as well as custom duct work for our jobs. With this machine and our plasma cutting table, we are able to make any custom duct work and fittings that our jobs require. Since we make it ourselves, our duct work is of the highest quality available.
Whether you need one piece of duct, one fitting or hundreds of feet of duct, we are able to get you what you need.
We're proud to receive Angie's List (now Angi) Super Service Award for the fourth year straight. Find out what others are saying about us!
