One of the three beach cities on Santa Monica Bay, and permits now go through a new online portal.
Redondo Beach is one of three adjacent beach cities along the southern portion of Santa Monica Bay, and the exposure that comes with it is relentless rather than dramatic. Salt air works on fasteners, flashing and coating edges every day of the year, rain or not, and it takes years off a deck detailed as though it were inland.
The city runs 30,609 housing units at nearly 5,000 per square mile, split almost evenly between owner and renter occupied at 51.4 percent against 48.6 percent. So there is real volume on both sides: private decks and terraces, and shared walkways, stairs and stacked balconies on multi unit property.
The first thing that goes on a coastal deck is usually metal. Fasteners lose section, edge trim rusts from behind, and stair connections corrode at exactly the point where they are carrying load. A rust stain bleeding up through a coating is not cosmetic, it is a report on what the hardware underneath has been doing for several years.
The second thing is the termination. Where a deck dies into a wall, where a post comes through the surface, where a stair lands: those are the places salt-laden moisture concentrates and the places a coating alone was never going to hold. We rebuild those with flashing and mechanical terminations instead of relying on sealant to do a structural job.
On multi unit buildings we phase the work by run so residents keep a route in and out, and on private property we plan staging around tight beach city lots.

Yes. The city launched the iWorQ Portal on March 31, 2025, and contractors, architects, engineers, designers and owners must submit all planning and building applications online through the Citizen Portal. Anyone working from older instructions is out of date.

Both, in roughly equal measure. The city splits 51.4 percent owner occupied against 48.6 percent renter occupied, so private decks and shared walkway work are equally routine here.
A professionally installed waterproofing system typically lasts many years. Capital Deck & Stair backs most projects with an 8-year warranty on workmanship, and proper maintenance can extend the life well beyond that.
Cost depends on the surface size, condition, and the coating system required. We provide a clear, itemized quote after a free on-site inspection, with no obligation and no pressure.
