http:www.Deltamechanical.com How Laundry Conversion is Done. Multifamily Repipe. Commercial Repie by delta mechanical. Laundry Conversion is the replacement of the central laundry facility with individual washers and dryers for each residence in a multifamily structure. Our turnkey service includes the removal and termination of the existing piping in the laundry room, repiping all units to accommodate individual washers and dryers, installation of the new washers and dryers, as well as refinishing, computer-aided paint matching, painting of the affected areas, and patching, texturing, and painting of ceiling areas that are used for access to the existing pipes and/or for the replacement pipes. We can also submeter each individual unit so that the accountability for the water and electric bill rest solely with the tenant.
