Building repair and general contracting in Marin and Sonoma County, from the company that already works on your plumbing and HVAC. We are a licensed California general contractor, license #501853. When a repair leaves a wall open, a leak damages a ceiling or a remodel needs several trades working in order, you deal with one team instead of coordinating separate contractors.

Water damage is the clearest example. We fix the source, which is usually a plumbing problem, and then repair the damage: drywall, framing and finish. That means one company, one point of accountability and fewer handoffs between the plumber and whoever repairs the wall. The same applies when a repair turns into a bigger project than you expected.

We have served Marin and Sonoma homes for over 40 years. Marin homes are served from our San Rafael office, and Sonoma County homes from our Santa Rosa and Petaluma offices. Call us and describe what you need, and we will tell you how we would approach it.

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.

Digout + Floor Repair

We were able to fully reset and paint this hardwood floor after a digout job until it was back to exactly how it looked before the start of the project.

When One Company Makes Sense

  • A leak is fixed, but the ceiling, wall or floor still needs repair
  • A plumbing or HVAC repair means opening up drywall or framing
  • You are planning a remodel that needs plumbing, HVAC and electrical coordinated
  • Water damage has left drywall, framing or finish that needs replacing
  • You are tired of coordinating several contractors for one job
  • A repair has grown into a bigger project than you expected

Frequently Asked Questions

Are you a licensed general contractor?

Yes. John Owens Services holds California license #501853, covering general building plus plumbing, HVAC, radiant and electrical work. That is why one company can take a project from diagnosis through finished work, with the trades coordinated in-house. Call us with questions about your project.

Do you handle water damage repairs?

Yes. We fix the source, usually plumbing, and then repair the damage in drywall, framing and finish. You deal with one company for the whole job instead of finding a separate contractor after the leak is stopped, which keeps the work moving.

Can you repair the wall after a plumbing or HVAC repair?

Yes. When a repair requires opening drywall or framing, our general contracting side can close it up and finish it, so the job does not end with a hole in your wall and a search for someone else to fix it. It is the same team throughout.

Do you take on remodels and larger projects?

Yes. We handle remodels, repairs and whole-home projects, with plumbing, HVAC, radiant and electrical coordinated in-house. Call us to describe the project and we will talk through how we would approach it and which trades are involved. Call us to get started.
