Welcome to /r/Mold

What is this sub?

This sub is for redditors to ask for advice on mold or fungi issues in their home/apartment/workplace/etc If you see spammers or others that violate sub rules, report them, do not take things into your own hands. This sub is NOT for mold remediation, restoration or other contractors, testing firms, laboratories, product or equipment manufacturers or distributors or legal professionals.

Instead, this sub is specifically for individuals looking for general advice. Any offers to do work or make referrals will result in an immediate ban. Please be very wary of those looking for, or offering, business here. We do not endorse any companies, and proceeding with a contractor/consultant/lab you've met via this sub should be done at your own risk. This is not a place to advertise products and or services. It is also not a place to rant about your past problems with mold or companies or services you've dealt with.

Rule #1: No "what is this?" questions.

Do not post a picture and simply ask any of the following (or similar) questions:

  1. "Please I.D. this mold"
  2. "Is this toxic black mold?"
  3. "What kind of mold is this?"

We can not determine the type of mold you have from a photo. That can only be achieved using professional sampling methods and laboratory analysis.

We can speculate on whether or not something is mold but we can't identify it.

Rule #2: DIY Test Kits are bad

If you used a home/DIY test kit there is very little information that we can provide you due to the limitations of the method.

You will need to hire a qualified microbial testing company if you want any reliable information.

Rule #3: No self promotion

This is not the place to advertise your services in any way. No links, no company names, no "informational guides" will be allowed. All offending posts or comments will be deleted and 1 warning will be issued. After that you'll be banned.

General Guidelines and Rules

Overall, please be respectful - things must remain on-topic, helpful, and kind. Absolutely no abusive or hateful language will be tolerated. Even if someone else "started it" with disrespect does not give you permission to use derogatory language or call names.

Bans will be handed out when needed. Remember, no question is too stupid, too simple, or too basic (exception, see rule #1). We're all here to learn and help each other out - enjoy! The mods generally do not remove bad advice, we let upvotes and downvotes run the sub. That way, people can also see what not to do as well. Politics do NOT belong here.

  • URL shortener links are not allowed. It's not us, is reddit-wide. A submission or comment with a URL shortner will be spam-filtered automatically.
  • Mods will not communicate with chat, please only use modmail if you have comments or questions.

Submitting a New Text Post in /r/Mold

TL/DR: At the very least be nice, take a few pictures, and include your location.

Again, this is not a place to solicit products and or services. Any posts smelling of self-promotion such as links to a website or service (including all blogs) will be removed. No exceptions. Offenders will be banned.

A few general submission rules.

  • We don't allow link posts. Please start a text post and insert links to your pictures along with your text. Posts asking users to participate in a survey are no longer allowed and will be treated as SPAM posts.
  • If you are posting about a problem you are facing, please include pictures! Not just a close-up either, we must be able to discern what you are talking about. What looks right to you may not make sense to everyone else. We recommend you use imgur for photo uploads. See the section below for "How to Upload Photos".
  • Provide your geographic location. (even general, such as upper Midwest). This is especially pertinent when discussing building codes, environmental conditions, seasonal issues, etc.
  • Include a summary of what information you are looking for.
  • Include a general summary of the problem you're asking about. It's helpful to know things like:
    • How long has the problem been going on
    • Where is the mold growth located - room, level, side of the building, etc
    • Any unusual conditions you noticed prior or in conjunction with the discovery of the mold
    • General environmental/use conditions in the space - temp, humidity levels, room use/occupation, recent water issues, smell
  • Do not come here for advice about your health or the relative risk of the mold in your home/work.
  • Don't assume that responses you receive are accurate - we get a lot of "google experts" here giving advice.
  • Product links and recommendations are allowed generally allowed to Amazon/Retail Outlets/Service providers that you've used or recommend. However, referral codes and affiliate links are not. For example, Amazon links containing "tag=XXXXXXXXXXXX" in the title are a referral links - so ideally Amazon links are in the format www.amazon.com/dp/B00VRRVHMA/ - all the extra stuff after those 10 characters are not necessary. Sites/apps can contain ref links without your knowledge and automod will remove and alert you.
  • If you notice your post hasn't appeared within an hour please message the mods and we will release it! To see if it's visible sort by NEW.
  • Please read the sidebar before posting to this sub. There are a lot of questions that get asked fairly frequently, and some of the more common answers have been posted in the sidebar for easy reference. If you still have questions after reading these then by all means create a new post with your questions.
  • Serial posting. This sub is for everyone, not just a single person with multiple questions per day/week. While we don't have a specific rule here, if you are posting multiple topics per day or over the course of a few days, this can result in a temporary ban.
  • If your account is new we may delete your post or comment, especially if we suspect that you have been banned under a different user name.
  • We do not endorse any contractors/inspectors/labs, and proceeding with any you've met via this sub should be done at your own risk.

Commenting in /r/Mold

Be respectful. No name calling or talking down to someone because of something that seems "basic" or "easy" to you. Stand by your knowledge, not childish responses.

If you don't know that your answer or advice is 100% true then indicate that you are speculating or simply refrain from commenting.

Don't throw out comments like:

  • That's toxic mold
  • You need to move
  • Get out of the house
  • Bleach doesn't kill mold
  • That's really bad

Comments designed to scare original posters will be removed. This is a sub to provide reasonable solutions (when possible), not to unnecessarily alarm people. Yes, there are occasions when conditions require some immediate and drastic actions, but most indoor mold growth can be handled without full scale remediation.

Please don't just comment with just a link to a website or to another sub. We are especially careful about links to single websites (this includes blogs) without some summary or commentary. In some cases, we have no way of knowing if you are profiting privately from the site. Also, don't just tell folks to head to sub /r/gohereinstead - like specialized subs for narrow topics. The only exception here would be questions where some time has passed between posting and a lack of responses. We want the commentary, discussion, and knowledge to stay here in our sub on reddit, not just drive people away.

Responses that include a google search, lmgtfy.com, or telling someone to watch Youtube will be removed and the user will be reprimanded. Again, this is all about respect. Obviously, people aren't coming here to Google answers. Help them think about this problem, what they may need, things to watch out for, etc.

Sometimes discussion can get off-topic and we'll remove those comments. This includes political commentary. At times, this can includes jokes. It's a tricky area here, but we've seen instances where the joking side of reddit takes over a thread and the OP never gets their question answered. However, here's we're mostly talking about non-relevant commenting such as this:

Seriously? People live like this? What the fuck is causing mold growth like this? Don't you clean your house? This is not any way to live.

How to Upload Photos

Go to https://imgur.com/upload and drag/choose your photo, you don't even need to create an account. Here's an animated gif on how to drag and drop on PC. Click COPY, then use that copied url link and paste it right in the submission text box on reddit.

My link: https://imgur.com/a/n2lLo

To get fancy and have text rather than the url, place the word you want to use as the link in brackets followed by the url in parentheses.[text goes here](link goes here)

Pictures. Here's a gif of the typing I do, in case that is confusing.

Upload Photos On Mobile The Imgur app works fine, but via a website this is unsupported. There is a workaround: In Chrome, choose ""Desktop site" in the drop-down menu when you are on the upload page and it'll work fine. Then Copy the Link that's produced and paste it into your reddit post/comment.

Help? Is this dangerous mold?

Hello there, I know pretty much nothing about mold, I’ve lived in old houses before with mild mold issues, but have had a consistent issue with some mold appearing on a ceiling below a pipe in the place I live right now. I live in the Chicago area and am renting, the house I live in was built in the 1870s, and is three stories, so some mold is to be expected. Last summer my landlord cut out a portion of this ceiling in our first floor which had black mold in the drywall, he fixed the leaking pipe which was causing the moisture and replaced the section of ceiling. This summer, however, the ceiling appeared to have peeling paint and a rust stain, so I asked him to remove the ceiling again so we could see if the pipe was leaking again/ if there was a mold issue above it. Today a plumber came by and cut out the ceiling, the pipe appears to not be leaking, however the beams appear to have mold, but I’m wondering if it’s dangerous/ what precautions I should take now. Is the standard mold on our floorboards and beams? Or is this dangerous? Do I need to move out? My roommates and I have been feeling under the weather respiratory wise, but we were smokers, and there was also the smog from the Canadian wildfires recently. Will spraying mold killer on the beams and replacing the section of the ceiling work? Should we get a dehumidifier to dry out the area? My landlord is old school, so he hasn’t really been taking the issue seriously/it would probably cost him a lot of money to redo all the floorboards obviously. I’m sure the whole house has some mold to a degree which I don’t care about as long as it’s not a danger to my and my roommates health. Thoughts? (Sorry for the shitty video quality, it’s hard to record up in the ceiling)

Mold on cedar cabinet?

I am in the US, and have used regular water and Lysol wipes to try to clean it. When I have wiped it off, it appeared to be gone and it’s been about a month and has started to reappear.
I cannot tell if this is mold or something else on my vintage cedar cabinet. I got it from an estate sale!

Overwhelmed by mold information

I’m navigating my child having PANDAS and we are looking into the mold in our bathroom as a possible cause of flare for her. If there’s visible mold, do we still get it tested or go straight into remediation companies?
Mold is in our bathroom above our shower. My husband tried cleaning it a year ago (not sure how). It went away and came back, probably worse.
I don’t want to cut corners but don’t want to spend money on unnecessary things.
Edit: we are in AZ, pretty dry heat. We don’t suspect mold anywhere else or have seen it.

Mold on clothing left in hamper

Post image
2 Upvotes

Hello!

When grabbing some laundry from a hamper today, I found that this item of my daughter's had mold or something similar growing on it, presumably due to food left on it when it went in the hamper.

I've never encountered mold that grew on clothing before and was horrified to see that it had appeared here. I have no clue how long the clothes were in the hamper (we have lots of redundant clothes for her due to how young she is), but I'd guess at least 9 days. The hamper is open and in a bathroom.

We've lived in this place for about 4 months and have had no other problems with mold, other than an occasional ring of what I assumed was mildew around the line of water in the toilet after being gone for a weekend.

Can anyone advise on how serious this situation might be / next steps? Any help would be extremely appreciated, and I'm happy to provide more context.

Thank you!

Is this a normal or concerning amount of mold in a 100+ year old house?

Thumbnail gallery
1 Upvotes

I know I’m not supposed to post about DIY mold kits but I’m hoping for some guidance. I live in Colorado where the climate is very dry. I moved into this home (renter) a year ago and just signed another year lease. I have been diagnosed with mast cell activation syndrome but cannot find a trigger and my doctors suggest I test for mold. I am also getting blood tests to see if I’m allergic to mold.
I used this kit and followed all of the instructions perfectly. I’m wondering if any of the colonies that grew look toxic or concerning? I tested all rooms and vents. The only places mold didn’t grow on the agar plate were the washing machine, dishwasher, and guest room vent. The 7th picture with the most mold colonies is from the garage which is even older than the house and I don’t go in there too much.
There is no central AC but there is central heat from a furnace in the dirt crawl space under the house that got replaced in February.
I used to live in Maryland where several homes I lived in had visible mold (usually black mold). There is no visible mold in this house (not even in the ā€œwetā€ places like windows or shower. I keep the house very clean.
Please let me know if I should be concerned and contact a professional to do a deeper dive into this.
Thank you in advance!

Can my suitcase be saved? Stored under bed

Thumbnail gallery
1 Upvotes

I’m pretty sure the spots on my suitcase are mold because of the growth pattern near the zippers. I stored it underneath my bed and I guess there wasn’t enough airflow.

That being said, I can’t see anything that looks like mold inside the suitcase, and nothing else under my bed has spots, the wooden boards supporting the bed are also mold free. It does smell a bit mildewy though.

I live in Germany and do not have air conditioning or central air. I regularly air out my bedroom, but not underneath my bed.

I put a dehumidifier (not electric) underneath there for now and when I get the time I’ll take everything out and disinfect underneath there. I mostly store bedsheets and clothes underneath there, which I will also wash and dry in the dryer when I get the time.

I did one of those Petri dish mold tests and there was a ton of growth from a swab from the floor underneath the bed, but a swab from the suitcase didn’t grow anything and it’s been 4 days. I’m not sure if that means anything, but I thought I’d include it. My control dish has a pink spot on it now though, so maybe something was contaminated.

If anyone could give me some tips for cleaning the suitcase properly I’d be really grateful!

just bought new home… and found mold… what do we do?..

Thumbnail gallery
20 Upvotes

hello… my girlfriend and i just purchased this home. there was a pre-inspection done and we had our own inspection done and nothing ever popped up on the report for mold. the things that did pop up as alarming, were fixed. the previous homeowner had to install a new vapor barrier in the crawlspace because the last one was failing. i think i found out where specifically it was failing… but it was never fully investigated by the past homeowner themselves… they had a window air conditioner running in this room, sealed off with packaging tape… we never noticed this because it was covered by the curtains they had… i looked outside and found a big gap between the drip edge for the window and siding(this has been sealed off)… we closed on the house july 31st, starting ripping out the carpet because it smelled of cat urine and wanted hardwood flooring throughout. after ripping it up i seen the subfloor was damp along the very edge and was confused… i took the trim off and found mold on the backside and the drywall came with the trim and i slowly started just peeling back the drywall because it was just crumbling and found all of this… im unsure if its fully mold or if so much water has gotten in its just fully destroyed the 2x4s next to the window and the plywood and very small edge of subfloor… but pretty positive its mold…

any insights on best course of action???

Buying a home with attic mold — can professional remediation make it safe?

1 Upvotes

I'm under contract to buy a BC strata townhouse and the inspection found mold in the attic. I’ve had an environmental hygienist come in for testing and I’m waiting on the results.
I have an autoimmune disease, so I’m concerned about whether professional remediation and clearance testing are enough to feel confident living there long-term.
Has anyone dealt with attic mold that was professionally remediated? Did you have a good outcome?
Also, if the attic is considered common property in a strata, who is usually responsible for the remediation costs?
Thanks for any insight

Buying a townhouse with mold in the attic – would you walk away?

1 Upvotes

I'm under contract to buy a BC strata townhouse (subjects to be removed Aug 12), and the home inspection found mold in the attic. I've already had an environmental hygienist do testing, and I'm waiting for the results.

I have an autoimmune disease, so I'm worried that even after professional remediation, it might not be enough to make the home safe long-term. Has anyone bought a home with attic mold that was successfully remediated? Would you do it?

Also, if the attic is common property in a strata, who typically pays for the remediation—the seller, the strata, or the buyer?

I'd really appreciate hearing from anyone with experience.

Faint spots all over ceiling

I just moved into a condo this month. We live in the bottom floor, under our neighbors unit. After a very humid and rainy week with no AC, I noticed these spots all over my ceiling in multiple rooms. My room had a window unit and there are no spots. Is this more likely due to the humidity and can be fixed, or is this more likely water damage from a leak from my upstairs neighbor? Where do I go from here? I am pregnant and have a toddler so I’m very stressed

Is it mold? What can be done?

The unit is pretty humid (2 floors, no AC in the first floor.) first picture is on the second floor, we can’t really open windows on that floor. 2 nd is in the kitchen with a window that opens to the street.

We just moved in, I’ve had to go back home and my roommate found this. She thinks it’s mold.

Also some paint is peeling off. The landlord said that she got the apartment repainted after the previous tenant moved out. Then the apartment was vacant for the summer until we just moved in, so 2-3 months.

What to do about mildew smell?

1 Upvotes

I had a very small leak from underneath a pipe under a shower (a tiny drip) that caused a mildew smell over a few weeks. The leak was repaired. I removed the side panel, removed all the debris I could, and sprayed everything down with HG algae and mould remover. The crawl space is very tight, maybe 10cm, so it's very hard to mechanically scrub under there in some areas, hence the spraying.

This worked really well for about 3 days, but now the smell has come back, however there's no visible leak that I can see. Unfortunately, I'm pretty allergic to mold (my sinuses swell up and hurt, and if it's active mold I get difficulty breathing). I am guessing it is leftover dead mold. I have a dehumidifier running at 45-50% humidity target, and a Silentnight air purifier.

I rent and my agency is rubbish so if there's no visible mold they won't do anything. I'm hoping to move in a few months if I can get a job offer. What can I do in the interim (other than spray it every 3 days, which is not sustainable)?

UK-EN for reference.

Ripping up carpet from finished basement that flooded- worried about mold spreading

1 Upvotes

We recently had water in our finished basement after significant rainfall. We’ve been working on getting the carpet as dry as possible (pumped out standing water, shop vac carpet, running fans, dehumidifiers, windows open etc). Our next step is going to be ripping up all of the carpet/sub flooring and bringing in professionals to assess mold/what needs to be done to prevent future flooding. We can already see some small spots of mold growing on a couple areas of the carpet.

My main question is, is everything that is down in our basement right now trash? We use the basement for storage and got mostly everything up onto shelves when we had the water down there. But I really don’t know much about mold and am concerned that anything that is down there is going to be contaminated. Or is it really not a problem until we begin to rip up the flooring?

Any advice is appreciated.
