Hollywood's residential fabric is overwhelmingly multi-family, and a remarkable amount of it dates from the 1920s and 1930s — courtyard buildings, low-rise apartment blocks and the occasional mid-rise, much of it now approaching a century old.
That age drives most of what we handle. Buildings of this era carry cast iron waste stacks and galvanized supply lines, and both are now well past the point where failures become routine rather than exceptional.
Alongside that is a substantial commercial base — production and post-production facilities, retail, hospitality and offices — where a water loss costs revenue every day the doors stay shut.

Cast iron stacks in ninety-year-old buildings
This is the failure mode that defines Hollywood's residential work and it gets far less attention than it deserves. Waste plumbing in 1920s and 1930s buildings is cast iron, and after ninety years it corrodes from the inside, with horizontal runs and the base of vertical stacks going first.
It rarely fails dramatically. What happens is a slow seep inside a wall or a floor assembly that runs for months, travelling between units in a multi-storey building before anyone connects a persistent musty smell to a cause. By the time there's a visible stain, the framing and the cavity have been wet a long time and there's established microbial growth.
When we're called to a recurring damp area in a building this old with no supply-side source, the stack is high on the list. It's also why we open and inspect rather than drying the visible surface and leaving — a stack failure dried without being found simply comes back.
Cascade losses and soft-story retrofits
Buildings of this era were built with vertically stacked kitchens and bathrooms, so a failure in a plumbing column concentrates damage into the same corner of every floor. One failure, four units.
Drying it means treating the column as one job — opening the cavities that carried water, drying ceiling assemblies from both sides where access allows, and containing per unit so residents can stay in place. The claim side needs scope separation documented on day one between the building policy and individual tenancies.
Many of these are also subject to Los Angeles' mandatory soft-story seismic retrofit ordinance, and retrofit work disturbs plumbing, wall assemblies and drainage untouched for decades. We're regularly called to buildings where a loss surfaced during or shortly after that construction. That's not an argument against retrofitting — it's a reason to take moisture readings before walls are closed back up, while access is easy.
Commercial work that can't stop
Production facilities, post houses, retail and hospitality all share a problem: closure costs more than repair. A facility on a schedule loses bookings; a hotel loses room nights it never recovers.
We structure that work around operations — overnight and weekend crews, phased containment so unaffected areas stay in use and presentable, and equipment staged out of customer and production areas during operating hours.
For post-production and technical facilities there's an additional rule: don't power anything on. Electronics exposed to water keep corroding after the water is gone, and specialist decontamination has a short window before damage becomes permanent. Business interruption and extra expense coverage exist in most commercial policies and are badly underused — we supply the restoration timeline and daily logs that support the claim.

Why us, here
Why Hollywood residents call Drycore Restore
Cast iron is the defining local failure
Ninety-year-old waste stacks seep inside walls for months and surface in a different unit than they started. It is the most under-diagnosed loss in this neighbourhood.
Cascade losses treated as one column
Vertically stacked kitchens and baths concentrate a break into the same corner of every floor beneath it.
Production facilities cannot lose bookings
Post houses and studios run to a schedule. Overnight crews and staged equipment keep the floor working during the day.
What Hollywood calls sound like
Most Hollywood residential calls come from buildings around ninety years old, and a surprising share trace back to a cast iron drain stack rather than anything on the supply side.

Both. The same crew that extracts and dries also installs the new drywall, matches texture, paints, and reinstalls trim, flooring and cabinetry — so the job actually finishes instead of stalling between two contractors.
