At Door Controls USA, our commitment to customer service is not limited to our extensive inventory. Our parts department is staffed with knowledgeable sales representatives from 7 a. m. to 5: 30 p. m. CST, Monday through Friday, because we want you to be able to service your customer as quickly as possible. And for those times when your service technician needs a little help working through a challenging installation issue, our technical support personnel are available 24 / 7 / 365 to help guide them. Our core business is in re-manufacturing automatic door parts and pieces with repair and replacements - the largest in the nation for this (If you walk through a Lowes, Target, Home Depot, and if the doors open by themselves, there's a 90% chance that our parts are in that door making it operate) . We have a contract hardware team (have done DCM hardware for 15-16 years) doing manual door parts and hardware (including the doors for that) - we do it on the new construction side.
