Wall seepage is one of the most common — and most misdiagnosed — problems in Bangalore homes. A damp patch on an interior wall could mean five different things, each with a completely different fix and cost. This guide covers what wall seepage waterproofing actually costs, what causes it, and why exterior treatment almost always matters more than interior fixes.

Interior or Exterior — Which Actually Fixes It?
A damp patch shows up on the inside wall, so the instinct is to treat it from inside. But that patch is almost always a symptom of a problem originating on the exterior surface — the interior treatment addresses the symptom, not the source.
When interior injection grouting alone is enough:
- One isolated crack or joint, not spreading
- No visible cracking on the exterior surface at that location
- Damp appeared once and has not recurred
When exterior treatment is necessary:
- Seepage recurs every monsoon at the same spot
- Visible cracks, peeling paint, or efflorescence on the exterior wall
- Multiple damp patches across the same wall
- Previous interior-only fix has already failed

What Affects the Cost in Bangalore
Four factors determine exactly where your wall seepage job falls in the price range:
- Cause of seepage — Surface cracks vs structural movement joints vs rising damp each need a different treatment
- Wall area affected — A single wall vs the entire exterior facade of a house
- Height and access — Upper floors of independent houses or apartment exteriors may need rope access, adding to cost
- Existing damage — Plaster damage or exposed rebar from long-term seepage needs repair before waterproofing

Wall Seepage Waterproofing FAQs
₹35–₹55 per sq ft for exterior coating treatment. Interior injection grouting for isolated cracks costs ₹4,000–₹10,000 per wall. Full exterior treatment for a standard house runs ₹20,000–₹60,000 depending on wall area.
Common causes include hairline cracks in exterior plaster, failed waterproofing at parapet or sunshade junctions, plumbing leaks inside the wall cavity, and rising dampness from ground moisture.
Exterior treatment is almost always correct since it stops water before it enters the wall. Interior-only treatment addresses existing cracks but doesn't prevent new seepage on an untreated exterior.
Properly applied exterior wall coating lasts 7–10 years. LoklFix provides written warranty on all wall seepage treatment using branded materials.
