Can Injected Damp Treatments Damage Your Home?

If you’re planning on buying an older property any time soon you could be entering into a world of unnecessary damp treatments. At the slightest whiff of dampit’s not unusual for mortgage lenders to insist on a ‘timber and damp report’, withholding part of the loan as a ‘retention’ (typically around £2,000) which can only be released once any necessary remedial work has been carried out backed by a 20-year guarantee.

The trouble is, this approach often results in a lot of unnecessary work being carried out. At worst, damp treatments can be counter-productive, damaging to the fabric of the property as well as being a complete waste of money.
