Mortgage not dependant - we have an unconditional offer from the lender.
This is what was said in the survey:
Damp proof courses not generally visible. We would anticipate they were installed and to type they are probably of double layer slate. Significant rising dampness was noted within the property and remedial works are required. Areas affected, particularly but not exclusively include the front bay window and left hand flank wall of the lounge and main bedroom. Timbers in contact with damp walls may also be affected by rot. Instruct an appropriately qualified person to make a thorough examination including underfloor areas to identify the cause and full extent of damage and to carry out all necessary repairs.
Although it does then also say in another part of the survey ("Risks to the Building"):
Testing internally with the aid of a conductance type moisture meter indicated no evidence of any significant rising dampness within the property. Seasonal conditions may affect the degree of penetration.
The conflicting statements make me doubt the legitimacy of the whole report... Have responded to the firm asking to speak with the surveyor to find out more about how they came to the assessment.
