Moisture in an older house: mistakes to avoid

Older buildings must be understood before they are corrected. Hiding the effects can worsen the issues or waste time.

Short answer

In an older house, you need to understand the source of the moisture before hiding the marks. Materials, the building's age, and usage may point to different causes.

Step 01

Mistake 1: treating every mark the same way

Saltpeter, mold, a damp band, and water damage do not always come from the same cause. The same building may even combine several causes.

Step 02

Mistake 2: refinishing too early

Plaster, paint, or wallpaper may deteriorate again if the substrates remain damp or if the cause has not been treated.

Does the damp keep coming back?

A fresh coat of paint will not stop water moving through a wall. MURSAIN finds the cause and uses the treatment that fits the building, dealing with the problem at its source.

Mistake 3: forgetting the professionals involved in the case

Notaries, insurers, tradespeople, property managers, or architects may need a clear reading of the issues before a sale, a claim, or works.
