lateral penetration
External defects are not always so easy to spot as a source of water ingress into a building.
From minor staining around windows...
...to major water entry from a downpipe hidden behind shrubbery and climbing plants which in this case led to extensive dry rot.
An 
survey carried out by a qualified CSRT surveyor will identify the type of dampness, identify the cause, and specify and carry out a cost effective solution covered by Guarantee.
All treatments will be carried out by staff recorded on the Professional Biocide User Register.
The guarantee can be separately insured by GPI for its 10 year duration on payment of a one off premium.
