Case of persisting damp / seepage issues even after Refurbishing and Rectification work in a Duplex Home

The Background

A duplex in a premier residential complex.

  • Refurbishing / rectification jobs and re-painting done recently to repair damp walls / seepage problem.
  • Source of Damp / Seepage not identified.
  • Problem resurfaces

This is where Team – MACJ – A Buyers Choice Home Inspections, came into picture.

The main concerned area was the Dining Hall.

It was badly affected. There were:

a) Paint discolouration on right wall lower portion around switch socket board.
b) Paint discolouration on right wall lower portion at mid span.

Adjacent Kitchen Wall

  1. The client informed our Team that there had been some past history of leakage around floor drain outlet and rectification works have been done for it. No active leakage was noted.
  2. Minor leak noted around junction of sink flexible drain pipe with outlet pipe on wall.
  3. Dripping water noted on wall surface under counter stone.

Observation 2 : Visual image of sink flexible pipe junction on wall

Observation 3 : Water dripping stains from counter and wall tile junction

Our Team thoroughly inspected and found that there were multiple sources from the adjacent Kitchen Wall side.

As analysed by IR camera, moisture presence noted in the affected area due to intrusions from:

  1. Leak at junction of sink flexible drain pipe with outlet pipe on wall.
  2. From joints between wall tiles and counter stone.
  3. Also gap noted around sink tap.

Multiple sources identified

Floor drain outlet condition

Leakage from sink flexible pipe at outlet joint

Deteriorated sealant at counter stone and wall tile junction

IR images confirmed water running along the surface of the wall which was spreading around the junction, thereby affecting the adjacent right wall of Dining area.

However, there was another source, which was more challenging.

Kitchen Balcony

We observed popping of paint on left wall and back wall lower portion above skirting. As confirmed by IR camera, the area was affected due to leakage from elbow joints of AC drain pipe running concealed along the affected area and spreading to the dining area wall.
