We are want to put in an offer for a house but the surveyor acting for the mortgage company says that we must have the roof timbers treated to eradicate beetle and fungus infestation. Could you give us an idea of the cost?
I would obtain quotations from specialist firms operating in this highly competitive field, but here are some approximate costs. If this course of action is to remedy an existing problem (and not a preventative measure) then reduce your offer by the amount you are quoted. Spray exposed roof timbers (with two coats of fungicide and insecticide) £10 per square metre Lift floor boards and spray (with two coats of fungicide and insecticide) £8 per square metre.
