Water System Diagnosis Your hot and cold water system is inspected to assess the level of repairs needed as well as the layout of your pipe system. Using this information, our technicians outline which pipes need to be replaced and the least invasive plan to carry out those replacements. Re-piping The pipes under your home that need to be replaced are removed. Small sections of drywall from the flooring up to the faucets of defective pipe are cut away and the pipes removed. Pex pipe is then installed in place of the defective pipe. Repair Restoration Areas where walls have been disturbed or impacted are repaired. Drywall is patched and prepared so that it is in a paint-ready condition.
