About Pool Mastic Pros

One specialty. Done right. Every time.

Most contractors treat pool mastic as an afterthought between bigger jobs. We built an entire company around getting that one joint perfect, because it is the difference between a protected pool and a five figure deck repair.


Our Story

We chose narrow and deep on purpose.

Pool Mastic Pros started with a simple observation. On nearly every aging pool deck in Southern California, the expansion joint had failed, and almost nobody specialized in fixing it correctly. Handymen overlaid new sealant on top of old. General contractors rushed it between larger jobs. Homeowners paid twice when the shortcut failed within a year.

So we did the opposite of going wide. We went narrow and deep. We replace pool mastic and expansion joints, and that is all we do. Every crew is trained on the same disciplined process, every job uses commercial grade materials, and every installation is backed by a written 2 year workmanship warranty. When a service is the only thing you do, you get very good at it.

That focus is also how we protect the people doing the work. We hold CSLB license #924754, we pay real wages, and we invest in our crews and their benefits. We are not the cheap version of this service, and we never will be. We are the specialist you call when you want it done once and done right.

The Work

Three steps, and we do not skip one.

There is no clever shortcut in this trade. There is only doing each step properly, on every job, whether anyone is watching or not.
