I highly recommend Mark for any plumbing issues.
Mark Mendoza squeezed my call into his already busy day because I had a 12-gallon-an-hour leak at 4 p.m. on a Thursday before the holiday. He is very knowledgeable in leak detection and found my water leak within 30 mins. Understand this leak was not obvious. I highly recommend Mark for any plumbing issues.

We unfortunately had a water leak in our home. Matthew came out and did an amazing job of assessing the problem, taking pictures, and letting me know my options with insurance. We will definitely have Oak Plumbing do the work once the contractors are done with their piece. I highly recommend them to anyone with water issues in their home!

Water leaks, no matter how small, can have a big impact on your home’s structure and your wallet. Oak Plumbing offers professional leak detection services to find and fix leaks at their source, preventing further damage and conserving water. Leaks aren’t always immediately visible.
