Cole was professional and got the leak repaired faster than the estimated time, which is nice to know that Precision doesn’t pad their time to make more money on the job. Very good job.

Terry Arellano
Darren was AWESOME! He goes over and beyond the call! He was so patient and very knowledgeable. He fixed everything and cleaned up after himself. He’s super nice to boot. I highly recommend Precision Plumbing for your plumbing needs.

Precision Plumbing & Contracting was absolutely amazing! They gave me the best quote around, scheduled me quickly and did a awesome job installing our tankless water heater. Darren was punctual, professional and really showed what a skilled professional can do in a short amount of time. 10 out of 10 would highly recommend!

I had a first-class experience with Precision Plumbing. From the initial call with Byron, who promptly scheduled an appointment, to working with Darren, the plumber assigned to the job—everything was seamless. Darren got started right away, worked efficiently, and completed the job quickly. Their pricing was very reasonable, and the overall service exceeded expectations. Highly recommend!
