Problems We Solve

Damp Patches After Rain

Damp patches that appear or worsen after rain are often a sign that moisture is entering the property through the external building fabric. While the visible damp may appear internally, the cause is often linked to external defects such as masonry, pointing, roof details, gutters, render or window surrounds.

What Damp Patches After Rain Could Indicate

  • Penetrating damp caused by defective pointing, cracked render or porous external masonry

  • Leaking gutters, downpipes, roof coverings, chimney details or flashing defects

  • Moisture tracking around window surrounds, sills, lintels or external openings

  • Damaged internal plaster or finishes caused by repeated moisture ingress

Why a Professional Survey Is Important

Damp patches that worsen during or after rainfall usually require a careful assessment of both the internal symptoms and the external building fabric. Treating the internal wall alone will not resolve the issue if moisture is still entering from outside. A professional damp survey helps identify the source of ingress, assess the extent of the affected area and determine the most appropriate remedial action.

How We Conduct Our Surveys:
  • Identifies the root cause

  • Avoids unnecessary treatment

  • Provides clear remedial recommendations

  • Helps protect the property long-term

How Northway Can Help

Northway can inspect the affected internal areas alongside the external elevations, roofline, rainwater goods and surrounding building details to identify how moisture is entering the property. Our survey-led approach provides clear findings and practical recommendations to help stop further water ingress and protect the property from ongoing damp-related damage.

Remedial Works Could Include
  • Repairs to pointing, render, masonry, gutters, downpipes, roof details or window surrounds

  • Removal and reinstatement of damaged plaster or internal finishes where required

  • Targeted damp treatment or moisture management measures once the source of ingress has been resolved
