Why Joints Fail Here

Manhattan Beach is hard on expansion joints.

Wind driven sand is abrasive, and in Manhattan Beach it never stops. It scours the top of the joint, opens micro channels for water, and once salt spray gets into those channels the sealant loses its grip on the coping edge. Sand in the joint is the tell we look for first.

Once the joint is open, water runs straight into the gap between the deck and the bond beam. It saturates the base material, and from there it lifts pavers, separates coping stones, and works into tile and plaster. The joint is a few hundred dollars of sealant. The deck it protects is not.

Manhattan Beach is a regular stop on our Los Angeles County route. We book these first thing in the morning so the crew is prepping while the deck is still cool, which gives the sealant the best possible bond.

How It Works

Pool mastic replacement in Manhattan Beach, three steps, one day.

Measure and quote

We price on linear feet of joint, so the quote is a real number rather than a range. You can measure it yourself in Google Maps in about two minutes, or we will confirm it on site. Either way the price you are given is the price on the invoice.

Full removal and prep

Every inch of the old mastic comes out, wall to wall. We never lay fresh sealant over failed material, because a patch bonds to the old mastic rather than to the concrete, and it fails on the same timeline the old one did. The joint is cleaned, backer rod is set to the correct depth, and both faces are prepped.

Fresh sanded install and cure

We install a premium sanded polyurethane sealant in grey or tan, tooled to sit slightly below the deck surface so foot traffic never catches it. Most jobs finish the same day. Stay off the joint for 48 hours while it cures and it is done.

Manhattan Beach In Detail

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

Local Conditions

What actually shortens joint life in Manhattan Beach.

Two things shorten joint life this close to the water. The first is chloride, which arrives on the breeze whether or not anyone swims, and attacks the bond line rather than the sealant itself. The second is the marine layer. Mornings stay damp well past sunrise, so the joint spends hours wet, then bakes in the afternoon. That wet to dry swing, every single day, is harder on a sealant bead than a much hotter inland climate that stays dry. In Manhattan Beach that shows up on the decks around The Hill Section, The Sand Section, The Tree Section and Manhattan Village, which is where most of our Los Angeles County work starts: a joint that still looks continuous from the patio door and is already open when you kneel on it.

Decks We Seal

The decks and coping we work on around Manhattan Beach.

Salt exposure changes what we do rather than what we charge. The joint walls get cut back further to reach concrete that has not been affected, and we vacuum rather than blow the channel, because moving salt dust around simply relocates the problem. Beyond that it is the same commercial grade material and the same two sided bond we use everywhere. On Manhattan Beach properties we size the backer rod to the joint we find rather than to a standard, and we cut both faces back to sound concrete before anything new goes in. That is the part you never see and the part that decides how long it lasts.

On The Day

How a job in Manhattan Beach runs, from booking to cure.

Most pools in this area finish inside a single visit. The quote is fixed in writing before we schedule, so the number you see is the number you pay, and it does not move because the joint turned out worse than it looked. We work the perimeter, so the rest of the garden stays usable while we are there. Booking a Manhattan Beach pool is the same process as any other. Measure the run, take the fixed price, pick your date. Nothing is charged until the work is finished and you have walked the joint with the crew.

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.

Manhattan Beach Questions

What Manhattan Beach pool owners ask us.

What does a pool mastic job cost in Manhattan Beach?

Pricing is simple, so there is nothing to work out yourself. Up to 80 linear feet is a flat $1,280. Past 80 feet you add $16 a foot up to 125, then $15 a foot up to 200, and $14 a foot beyond that. You get the exact number in writing before we schedule, and nothing is charged until the job is complete.

Why not just fill the cracked part?

We do not, and it is the main thing separating us from a general handyman. Fresh sealant laid over old mastic bonds to the old material rather than to the concrete, so the patch fails on exactly the timeline the original did. We remove the full run wall to wall so the warranty actually means something.

What does the finished joint look like?

Grey or tan, both in a premium sanded finish. The sand texture matches typical deck surfaces so the joint reads as part of the deck rather than a stripe across it, and it is far less slippery underfoot than a smooth sealant. Most owners match the coping rather than the decking.

Do you work in The Hill Section?

Yes. The Hill Section is one of the areas we cover in Manhattan Beach, along with the rest of the city. We hold CSLB license #924754, and we carry the certificates most HOAs and property managers ask for.

What happens if the joint fails again?

Every job carries a two year written warranty covering the sealant and the workmanship. You get the certificate with your paperwork. A warranty visit costs you nothing, and settling the invoice has no effect on your cover.
