Damp-proofing Attic Beams

[Old]

Hi all. Any idea how much the above usually costs?

Hi, Nothing usual about dampness in an attic, first establish the cause of the problem, then check to see if the damp has caused a long term problem for the timbers. It is important that the treatment is the right one for the job, some are for prevention others are treatments for problems like wet or dry rot.

Why would you want to damp proof an attic beam?
Contrary to one of Peter C's comments, this isn't usual in new houses or indeed most older homes.
While Georgian houses can have trouble under valley gutters and behind parapets, most attic timbers above the wall plate level are usually okay, assuming no slates have gone missing.
However I echo Peter C's advice to check the timbers.

More important is to discover the cause of any damp occurrence.
So the first question is - has there actually been a damp occurrence?
Is it clear what's causing it - water ingress is often assumed, but a house produces a lot of water vapour a day.
Interstitial moisture collecting in attics without proper vapour checks or ventilation is one "invisible" source of dampness in roofs.

FWIW

ONQ,

You had me a little concerned thinking that I would ever say it's usual to have damp timbers in the attic. Thought it best to highlight the above.

A thousand pardons Peter C. I am an ass. I misread your post. Sorry. And thanks for pointing it out.
