Mold and Ceiling

Hi everyone,

We found a house that is in our favorite neighborhood and of the right size but has a few issues we are not quite sure if they are fixable.

We found a couple mold spots in the ceiling of the top floor, with the vinyl flipping off in the exterior we suspect that it could come from a leaky roof. We are prepared to change the roof, but is it possible to remove all the mold in the attic and if so how much will it cost?

We also saw in the basement ceiling there is water damage. That spot appears to be under a washroom. How much will it cost to fix the whole thing? What's the chances of the leak causing widespread damage? Looked like the leak has been going on for at least a year cause it's been rented out that time and the owner is out of country.

Thank you in advance for your help!

Mold remediation is definitely something that needs to be assessed in person. You could probably gauge it yourself by having a look up in the attic. If it looks like the wood is in decent condition and there doesn't seem to be thick areas of it, it could probably be cleaned and dried yourself.

The leaking toilet shouldn't be a huge issue. Give the toilet a shake and see if it is firm. If not the floor may have rotted.

If the damage on the ceiling is not too bad chances are the fix will be fairly minor. If the ceiling looks real bad then there may be mold growing and the wood framing maybe damaged

Sorry I can be more specific but it is hard to tell without seeing it firsthand.

Sorry I didn't see the picture before. That looks pretty significant.

What area is that picture? From the roof?

The picture earlier is the basement ceiling, directly under the first floor bath.

This is a picture of the bathroom ceiling on the top floor.

Not all dark spots are mold (mould). Some are simply water stains, but it shouldn't be ignored.

Depending on what is in the attic area, your concerns may be justified and I would consider a good deal of replacement. Prior to that, find out the cause and have that corrected.

As to the basement, it looks as though there was some leakage from the washroom, which I beleive is directly above. Again, find the cause, ... fix it, ... then do the added chore of replacing drywall and ceiling areas that require the work.

I don't believe it is a major issue, but be safe rather than sorry.

I think the damage is pretty concerning. I would take a revisit. Take a look at the Attic and also get permission to pull apart some of the ceiling. Use a heap filter mask. Just look at the framing. If it doesn't look like the wood is too bad then I wouldn't be too concerned.

Regarding price I would assume that they will both cost $2000 each. That should be a good cushion. For each you will have to fix the cause. Maybe temporary on roof. Clean mold. Get it tested by a air specialist. Repair insulation and drywall. Popcorn ceilings are a bit of a dog to repair well.

Mold issues can be very difficult, in some cases the effected area is minimal and in extreme cases they can be overwhelming to say the least. I would start by contacting a reputable Roofing / Siding contractor to evaluate the exterior envelope of your new home from top to bottom, in most cases they can determine the origin of infiltration and provide you with the best remedial solutions.

As for the removal of existing mold it could get quite costly depending on the amount and its properties, some molds are very hazardous and require abatement to the areas in question.

We wish you all the best, do your due diligence when hiring a professional contractor.

As part of your assessment I'd advise you to have a core sample taken of the bathroom ceiling to determine the existence of asbestos. If asbestos is evident in the insulation make sure proper removal and handling of this lethal material is followed.

Good luck with your findings and repairs.

I would be very concerned about the damage you show. Water can go anywhere and show up in unexpected places unrelated from what appears to be the source. The other thing that would be a major red flag is the fact the previous owner rented it out.

They obviously didn't care enough to do any repairs before selling it and don't appear to have taken care of the property. I would walk away.
