Containment goes up before any demo starts. An independent third party clears the work before we call it done.

Remediation done wrong makes the problem worse. Tearing into mold-affected drywall without containment aerosolizes millions of spores and distributes them through the whole house, turning a one-room problem into a whole-home problem.
The demo is the easy part. The containment is what you are paying for. Anyone can cut out drywall. Doing it inside a sealed, negatively pressurized envelope so that spores released during removal never reach the rest of your home is the technical work, and it is exactly the part that gets skipped when a bid comes in suspiciously low.
If you get a Chula Vista remediation quote that does not itemize containment, negative air machines, HEPA filtration, and clearance testing, you are not comparing it against ours. You are comparing it against a demolition quote.
West of the 805, the moisture source behind mold growth is disproportionately a slab leak or a failing cast iron drain in original mid-century plumbing. Those need a licensed plumber, and we coordinate the sequence so the wall is not closed before the repair.
East of the 805, in Eastlake, Otay Ranch, and Millenia, it is more often an upstairs supply line, a second-floor laundry hookup, or window and stucco flashing on newer multi-story construction. Tighter modern envelopes mean water that gets into an assembly has fewer ways out, so growth establishes faster than owners expect in a house that is only fifteen years old.
Confirmed mold in your Chula Vista home? Call True Core. IICRC AMRT-certified crews, negative-air containment, independent clearance testing, and a documented scope your contractor can rebuild from.
Six-mil poly containment with a zippered entry, sealed HVAC registers, and a HEPA-filtered negative air machine exhausting outside. The work area is held at lower pressure than the rest of your home so air flows in, never out.
Affected porous materials are removed inside containment, bagged inside containment, and wiped before they leave. HEPA vacuums and air scrubbers run throughout. This is the difference between remediation and redistribution.
We do not remediate around an active leak. The water source is identified and corrected, or the work is explicitly staged behind another trade fixing it, before anything gets closed back up. In Chula Vista that source is frequently a slab leak on the west side or an upstairs supply failure on the east.
A third party performs post-remediation verification before containment comes down. We do not clear our own work. If it fails, we go back in at our cost until it passes.
We do not sell reconstruction. A company that profits from the rebuild has a quiet incentive to remove more of your house than the standard requires. We take out what has to come out and document why, then hand your contractor the file.
Work begins from a written protocol, either from our inspection or from an independent hygienist you hired. We build containment with six-mil poly around the affected area, install a zippered decontamination entry, seal every HVAC supply and return inside the zone, and set negative air machines exhausting to the exterior through HEPA filtration. We verify negative pressure before a single piece of material comes off the wall. Setup runs two to four hours depending on zone size.
Affected porous materials come out: drywall cut back to a documented margin past visible growth, insulation, affected carpet and pad, and wood products too degraded to clean. Semi-porous framing and subfloor usually stay and get treated rather than removed. Everything is bagged inside containment and the bag exterior wiped before it passes through the decon entry. HEPA vacuums and air scrubbers run continuously. One to three days for typical residential scopes.
Remaining structural surfaces get HEPA vacuumed, damp wiped, then HEPA vacuumed again. Framing that held growth gets mechanically cleaned, sanded or media blasted where warranted, and treated with an EPA-registered antimicrobial. This is the phase that separates remediation from demolition: removing material is easy, properly cleaning what stays is the actual skill.
If the assembly is still wet it gets dried to a documented dry standard before anything closes up, using the same monitored process we run on water losses. The moisture source gets corrected in this window: the failed fitting replaced, the flashing repaired, the ventilation added. If the source is a trade outside our scope, a plumber on a slab leak for instance, we tell you plainly what has to be fixed and by whom, and we do not seal the wall until it is done.
With containment still up and air scrubbers still running, an independent third party performs post-remediation verification: visual inspection plus air and surface sampling against outdoor controls. We do not clear our own work, and we will give you the clearance provider's name so you know it is arm's length. If it fails, we go back in and correct it at our cost. Once it passes, containment comes down and you receive the clearance report plus a written scope of everything removed, which is what your repair contractor rebuilds from.

It prices on the size of the containment, how much material is removed, the number of days engineering controls run, and whether the HVAC system is involved. HVAC contamination is the biggest swing factor, because a contaminated duct system has been distributing spores to every room and the scope grows accordingly. Clearance testing is a separate line paid to the third party, and we keep it separate on purpose so you can see it is not ours.
No, and this is worth understanding. Bleach is mostly water, and on porous materials like drywall and framing the chlorine stays on the surface while the water soaks in and feeds the growth. It also does nothing about dead spores and fragments, which are still allergenic. Removal and HEPA cleaning is the answer, not a chemical.
Usually not. Proper containment is exactly what makes staying possible, since the work zone is sealed and under negative pressure and the rest of the house is protected. Relocate if the containment covers your only bathroom or kitchen, if the scope is large enough to involve the HVAC system, or if anyone in the household has significant respiratory sensitivity.
Because a company grading its own homework is not verification. Independent clearance is what makes a passing result mean something to you, to a future buyer, and to an insurer. It also protects you: if the test fails, that is our problem to fix, not a judgment call we get to make about our own work.
It depends entirely on the cause. Mold resulting from a sudden covered water loss is often covered, though many California policies cap mold at a specific dollar limit regardless of cause. Mold from long-term seepage, humidity, or deferred maintenance is typically excluded. We document the source carefully, because that documentation is what the coverage decision turns on.
Mold returning in a remediated area means the moisture source was never actually corrected. That is why source correction is part of our scope rather than something we leave to you. If growth returns in an area we remediated and the source was within our scope, we come back.
