Tustin Pool Protection

The specialist Tustin homeowners call for mastic.

In Tustin, pool decks take a beating. Tustin Ranch's newer pools are now reaching the age where the original joint begins to crack and separate. The flexible mastic joint that seals the gap between your coping and surrounding deck is the first thing to go, and once it cracks or pulls away, water reaches the soil underneath. From there the deck begins to move, slabs heave and settle, and a simple joint becomes a structural problem.

Pool Mastic Pros does one thing in Tustin: we remove the old, failed mastic completely, prep and clean the joint, set fresh backer rod at the correct depth, and install commercial grade, self leveling mastic in grey or tan with your choice of sand finish. Because mastic is all we do, every Tustin job runs the same disciplined process, finishes in a single day, and is backed by a written 2 year workmanship warranty.

We serve homeowners throughout Tustin, including Tustin Ranch, Old Town Tustin, and Tustin Legacy. You get a fixed price by text before we schedule, the pool stays unused for a 48 hour cure, and nothing is owed until the work is complete and you have seen the finished joint.

Tustin In Detail

What is different about pool decks in Tustin, and what is not.

Local Conditions

What actually shortens joint life in Tustin.

Older established neighbourhoods have the most overlays, and overlays are why a joint that was resealed two years ago can already be splitting. Sealant only performs when it is bonded to sound, clean, textured concrete on both walls and to nothing at all underneath. Layer it onto old material and the new bead is only ever as good as the crumbling thing it was stuck to. Tustin is not unusual in that respect, it is simply typical of Orange County. The pools near Tustin Ranch, Old Town Tustin and Columbus Square were mostly built within the same decade, so their joints are hitting the end of their service life at roughly the same time.

Decks We Seal

The decks and coping we work on around Tustin.

Original coping on an older pool is usually cast concrete or bullnose brick, and after thirty years the edge is rarely as square as it was. That is not a problem, but it does mean the joint width varies along its length, and the rod has to be sized for the widest point rather than the average. Using one size everywhere is the shortcut that leaves the bead sitting three sided in the narrow sections. Whatever the deck is made of in Tustin, the rule does not change: the sealant has to bond to clean concrete on both walls and to nothing underneath. Backer rod at the correct depth is what makes that possible, and it is the step most often skipped.

On The Day

How a job in Tustin runs, from booking to cure.

A typical residential job here is one crew, one day. We arrive between eight and nine, cut and remove the old material wall to wall, prep both faces, set the rod, install the bead and clean up behind ourselves. All we need from you is the gate unlocked and pets kept inside while we work. The pool cannot be used for forty eight hours while the mastic cures, and you do not pay anything until the job is finished. There is no separate Orange County rate card. Tustin is priced by the linear foot from the same bands as every other city we serve, and the figure is fixed in writing before we schedule.

The same everywhere. Price, process and warranty do not change by postcode. It is the same crew, the same commercial grade material, the same full removal wall to wall and the same two year written warranty whether the pool is at the coast or an hour inland. We price by the linear foot and we do not add a travel surcharge anywhere in our service area.

Tustin FAQ

Common questions in Tustin.

What color mastic is best for Tustin pool decks?+

We offer grey or tan, each with a sand or no sand finish. Most Tustin decks pair well with a color matched sand finish that blends into the texture. We match it to your deck when you book.

Why is the mastic around my Tustin pool cracking?+

Sun, heat, and constant deck movement break mastic down, and Tustin gets plenty of all three. Once the bead hardens it cracks and separates, and water starts getting through. It is normal wear, and it is exactly what we replace.

Do you serve all of Tustin?+

Yes, we service pools throughout Tustin and the surrounding area. If you are just outside the city line, call us anyway. Odds are we are already working nearby.

How long does a Tustin mastic job take?+

One day. We remove the old mastic, prep the joint, set new backer rod, and install fresh mastic in a single visit, then the 48 hour cure window begins.
