Found this in a down unit today, shut the water off... where do we go from here?

Strip unit now by mold mediation company, once sheet rock is out, treat unit and put dehu in unit to pull the moisture out...make sure there are no other leaks in the unit..

Call a restoration company. Maybe Ins. Company first and they might tell you what to do. I’d use dehumidifiers but if you use fans you might spread the mold spores.

Take out sheet rock, put humidifier in unit, your carpet comoany should have one , let dry out remove carpet and pad

Full remediation and don’t let anyone enter without proper PPE

I used Harbro and loved them. Looks like surface mold, have you found a leak? . I would call a remediation company and get their opinion. Yikes. Also call your insurance and file a claim, the cost to fix this will most likely be higher then your deductible.

Call a remediation company. Remove all drywall, flooring, cabinet, and anything else that is porous. Once that's done, make sure the studs are encapsulated. Studs need to be encapsulated due to they are a porous material. I would hire a 3rd party mold testing facility to do testing. They will give you a protocol that the remediation company will have to follow to pass a inspection. Dehumidifiers and air scrubbers need to be in the unit but please DO NOT put fans on it. Fans will cause the mold spores to spread the other areas and make the issue worse.

So sorry I've been in similar situations. That is why we started doing weekly vacant walks.... no fun!

FIRST CALL YOUR INSURANCE company to see if they have a pre-approved remediation company. Otherwise youvwill be paying for all of it.

Call a remediation company immediately, should be treated as a hazardous site until resolved.
Learning experience to make sure your vacant units are walked regularly.

Also, sorry about your unit. This isn’t a great situation but it is salvageable, I’ve experienced MUCH worse and worked through it.
Get it stripped down before the holidays, address the Renovation after the holidays,
Plus side, you can renovate and perhaps get a premium in the future

Insurance company will pay for property damage and warranty will pay for plumbing replacement/repair

Whatever you do don’t let anyone paint over it. The Sheetrock should be completely removed and replaced.
Before you do anything, cut a small piece of the affected Sheetrock and send the sample to EMSL to test it for mold. If positive for Stachybotrys you need to involve people who have remediation experience.

For the record, I had a unit look like this in 10 days. ???? I was walking all my vacants weekly, it was during summer, I took a week vacation came back walked my units and it was just a perfect storm situation. I feel you!

That needs Servpro or another bio clean up service. That’s not safe for anyone. Please tell me you wore protective gear and masks when you entered.

Depending upon the cause, you may want to call your insurance company to see if the damage is covered. If yes, they will arrange for the repairs. If not, get three quotes from reputable mitigation companies.

This calls for an expert contractor. But you need multiple dehu's asap, fans, a moisture meter. Air ducts clean, air scrubbers. This may be an insurance claim depending on your deductible.

Do not handle this yourselves. Pay the money to have a reputable company take care of this. I had a leak in one of our units shower that was leaking to the floor below. Went with the cheaper vendor and he said caulking needed to be redone. Seemed like a bandaid on a bigger problem. Called out Servpro and it was much worse than that. Entire shower pan had to be replaced and all dry wall between the units. There was more but that was gist.
I’d go with Servpro as well.
For the future though, your team should be in those vacants and doing a property walk every day. We turn the lights on in our vacants everyday. Helps as a selling point. No one likes a dark apt. If you can’t turn on electricity then open shades and blinds. It helps brighten things up, easier to lease but also you’re checking your units everyday. We caught a vagrant that broke into one of our vacants. We also found a unit where sewage had overflowed from the toilet and seeped out into the hallway and the apartment below. Which we had a move in, moving into the lower unit in 3 days. We were able to treat these issues right away before further damage could occur.
My first BM would have had my head on a platter if I came to her with this.
Good luck.

Yikes—first have a strong cocktail.
Looks like a job for Belfor or another trusted professional remediation provider. And keep all invoices and labor data for an insurance claim.

Looks like Sick building syndrome. Would take
Down to studs and remediate. All walls and ceiling down to studs and
Floor/roof joists. Remove all flooring to slab or subfloor if not a
Ground floor home. Fix source of moisture and or ventilation. Re-drywall all. Servpro is great start. Be careful in this unit and exposure to staff.

Walk vacancies daily or at least every other day so things like this won't happen

Please limit your time in there. That is so unhealthy to breathe.

I have been here. I'm so sorry. That discovery was a terrible feeling. A leak had developed unbeknownst to staff. We learned the "check on the vacants" lesson the hard way too. My unit wasn't quite this bad but still required extensive and expensive mold remediation, replacement of all flooring, cabinets, counters, molding, partial drywall, etc. It wasn't fun but my unit is now very pretty because I got to pick out new everything instead of the bland beige and oak. Silver lining? ????

Get a company. Too much and too hazardous for maintenance to do. All drywall walls infected needs to be removed. You need a DE machine in there until they come. This will stop more spread. Do not go in there with out a mask. Also if they had renters insurance you can make a claim to them and also your prompt insurance claim. Check surrounding units for evidence of mold as well.

Yep, that's gonna be a total redo. Need a remediation specialist. And call your insurance company.

May need to check any adjacent units to see if the mold has spread if you have. I agree that you should contact your insurance company and let their adjuster determine the extent of remediation required. Expect rates to increase though it's going to be expensive.

Look into sub-metering, with auto leak detection and alerts.
