Hi there,
The product you need is available at the Home Depot in Canada. It’s called Concrobium. It stops mold and mildew and it doesn’t come back. Ever. Concrobium is formulated from food-grade chemicals so it’s non-toxic. It’s a brand new product and I've used it to kill both the smell and reappearance of mildew in our basement. It rocks. www.concrobium.com
Here are the instructions for use:
1. Remove heavy soil from the surface to be treated.
2. Thoroughly spray the entire area with Concrobium (or apply with a Concrobium-soaked cloth or roller). . If surface has visible fungal growth or staining, additional scrubbing may be required. Note: Concrobium is safe for us on almost all surfaces, including wallboard, plaster, ceiling tiles, wood, metal, plastic, stone, concrete, tile, fabrics, upholstery. If in doubt, perform a test on a small, inconspicuous section.
3. Wipe off excess wetness.
4. Allow to dry overnight (16-18 hours). Do not rinse. Note: in the event of accidental over-application, a harmless white residue may form on the surface. This can be easily wiped away with a Concrobium-dampened cloth.
Concrobium is available in most hardware stores in the US and Canada.



Hi ther Toolgirl, have you thought why ba might be getting black mould in the first place, the humidity is too high in the house, you need a change of air, you could do with a Heat Exchange Fan, this draws in fress air & it is then heated by the warm stail air, the 2 air channels do not meet!
A great prouduct
Bye from the Dampman

Hi Olga,
I'm Mag's husband and thought I'd give you a quick answer as Mag may not be able to for a day or two.
The first thing is to find out if your insurance covers roof leaks and then get them to take care of it.
Ultimately, the roof will have to be patched, the insulation replaced and the mold sprayed while the insulation is out. So the quicker you get the roof fixed the better.
Hope that helps.

Oh, and Dampman, thanks for the air exchanger idea. We'll look into it.

I was just wondering if it is possible to get faint grey marks in new lumber or is that a sign of mold growing. Our house is two years old and saw it where the floor joists meet the board above the foundation. I had to remove the insulation to see it and the house is kept at 30-40% humidity. I hope it's not a leak there. No sign of mold on the insulation.

Scott,
It is possible and even common to have water marks and even mold marks on lumber in new homes. The marks often happen during shipping or construction and don't necessarily mean you have a leak or active mold.
You're humidity level wouldn't support mold growth but if you're concerned about active mold anyway, then I would suggest spraying with Concrobium Mold Control to lock in any spores and to prevent new growth. It's cheap and easy insurance.
