- The equipment, materials, power and labor necessary for such test shall be furnished by, and at the expense of, the owner or holder of the work permit.

Thank you for the recent work your company completed on my chimney cap. You spent a good deal of time to correct a long standing smoke problem I had in my chimney fireplace.
