Mold Remediation

Contained, Removed, and Rebuilt

Mold follows water within 24 to 48 hours. We stop the moisture source, contain the work area under negative air, remove the affected material, and put the wall back. With independent third-party clearance testing arranged before anything closes up.

Removing mold without fixing the water buys you a few months.

Mold is not really the problem. Mold is the symptom of a moisture problem that has been running long enough to grow something. Scrub it off, seal it up, and if the leak, the intrusion, or the humidity is still there, it comes back in the same wall, usually within a season.

So the first thing we do is find the water. Moisture readings and thermal imaging tell us where it is entering and how far it has traveled, and that gets corrected before a single square foot of drywall is removed.

Then the removal itself is done properly: contained, under negative air, with HEPA filtration, because remediation without containment is just redistributing spores into rooms that were fine an hour ago.

Wall opened to studs with affected material removed

Source corrected, affected material removed, wall rebuilt.

Six steps, in this order, every time.

Skip step two and you will be paying for step four again next year.

01

Assess & Scope

Moisture readings and visual inspection establish where the growth is and, more importantly, where the water keeps coming from.

02

Fix The Source

Remediation without stopping the moisture is a temporary result. The leak, intrusion, or humidity problem gets corrected first.

03

Contain

Work area sealed in plastic with negative air pressure and HEPA filtration, so spores exit the building instead of migrating into clean rooms.

04

Remove

Affected porous material cut out and bagged inside containment. Salvageable non-porous surfaces HEPA-vacuumed and cleaned.

05

Dry & Verify

Structure dried to measured standard, then independent third-party clearance testing arranged before anything gets closed up.

06

Rebuild

Insulation, drywall, finishes, and electrical restored under our General B license, same contract, same crew.

On Clearance Testing

We do not grade our own homework.

We recommend an independent third-party hygienist for post-remediation clearance on every mold project, and we are glad to coordinate it.

A contractor who tests its own remediation, then certifies its own pass, has an obvious conflict of interest, and the document it produces is worth correspondingly less to your insurer, to a future buyer, and to you. Independent clearance costs a little more and is worth considerably more.

Mold questions

Growth can begin within 24 to 48 hours of a water intrusion given the right temperature and an organic food source, which drywall paper and wood framing both are. That is why we assess for mold on every water loss instead of treating it as a separate problem discovered weeks later.

We assess visually and with moisture readings to scope the work, but for formal testing and post-remediation clearance we recommend an independent third-party hygienist. A company that both grades its own work and gets paid for the result has an obvious conflict of interest, and any clearance document it issues is worth less to you, your insurer, and any future buyer of the property.

On a small surface patch of non-porous material, surface cleaning can be reasonable. On drywall, insulation, or framing it is not, because the growth extends into the material not sitting on the surface, and wetting it down adds moisture to the exact conditions that caused the problem. Anything past roughly ten square feet, or anything inside a wall cavity, needs containment, not a spray bottle.

Sealing the work area in plastic, running negative air pressure through HEPA filtration so spores move out of the building not into the rest of the house, and controlled removal and bagging of affected material. Without containment, remediation in one room reliably contaminates the others.

It depends heavily on your policy and on the cause. Mold that results from a sudden covered water loss is often covered, at least up to a sub-limit; mold from long-term seepage or deferred maintenance frequently is not. Many policies also carry a specific mold cap. We document the source and the timeline thoroughly so your adjuster has what they need, but the coverage determination is your carrier's to make, not ours.

Yes, and that is unusual in this category. Remediation removes material; putting the drywall, insulation, and finishes back is general contracting work that most remediation companies are not licensed for. YKCA holds a General B building license alongside the C-10, so the same contract covers both.
