HVAC & Plumbing Jobs: Before & After Finishing Services

When plumbing or HVAC work opens a wall, ceiling, floor, or slab, our in-house building repair team restores the finished space too.

Rerouted Plumbing Pipe In Beautiful Bathroom

We protected a newly remodeled bathroom and rerouted a bathroom pipe that was causing issues for the homeowner who wanted their plumbing routed differently in their home. By protecting the freshly remodeled bathroom and expertly removing the ceiling sheetrock, we were able to go in and gain access to the pipes we needed. After making the necessary repairs, our building repair specialist went back to patch our cut-in and reinstall their bathroom light.

Replacing A Cracked Leaking Bathtub

Our client wanted to have a new bathtub installed. In the process, we found wood rot underneath the existing bath tub that our in-house building repair specialist had to repair. We successfully repaired the wood rot, installed a new tub, and matched the existing tile as best as we could, due to the manufacturer no longer making the same tile. Even when projects take an unexpected turn, you can rest easy knowing that John Owens Services can take your residential plumbing or heating job from start to finish and return your home back to its original state or even better.

Sewer Cleanout Installation & Concrete Repair

When a home main line sewer clogs, an accessible cleanout is required to perform a hydrojet drain cleaning or other service to clear the blockage. For this job, we cut into the client’s existing concrete to install a new cleanout. After the installation, we repoured and patched the concrete we cut and matched the color to the existing concrete.

Bathroom Wall Access for Pipe Repair

In order to be able to complete a successful plumbing repair, we need to access the bathroom plumbing pipes in the wall. For this project, we cut into the client’s bathroom wall to be able to work fully with the pipe system for the plumbing repair job. After the work was completed successfully, we re-patched the wall and re-painted to cover any signs of where the wall had been cut into, leaving the client’s bathroom with fully operational plumbing as well as a completely repaired and painted wall.

Water Service Installation

Our customer needed a new water service installed at their home. The job required us cutting into an existing concrete stamped walkway to install the new water service line. After the repair, we expertly matched the existing concrete color and stamp pattern. You would never know we were there.
