Damp causes
Rainwater goods and drainage investigation
Investigate gutters, downpipes and drainage as causes of penetrating damp, with clear referral boundaries.
Why diagnosis matters
Treat the cause, then repair the damage
Overflowing gutters, leaking joints, blocked gullies and poor ground drainage can saturate walls. We inspect accessible evidence and coordinate the right repair route rather than masking the internal symptom.

Common questions
About rainwater goods and drainage investigation
Can a blocked gully cause damp?+
Yes. Water can pond against walls or overflow repeatedly, increasing saturation and splashback.
Do you clear gutters?+
Yes. We clear and repair gutters, downpipes and rainwater goods, and carry out associated roofing work in-house. Below-ground drainage excavation is referred where needed.
Should internal plaster be repaired first?+
No. The external water source should be corrected and drying assessed first.
