Damp Remediation and Roof Repairs | Woodstock, Salt River and Observatory
All your Waterproofing, Damp and Roofing services in and around Woodstock, Salt River and Observatory in Cape Town.
Woodstock, Salt River and Observatory contain some of Cape Town's oldest residential and commercial buildings. Many were built in the Victorian and Edwardian eras with brick masonry walls, lime-based plasters, corrugated zinc or asbestos cement roofing, and no damp proof course. After decades of use — and often decades of poor repairs — these buildings typically present with deeply saturated walls, failed plaster, corroded roof fixings, and moisture problems that surface treatment cannot resolve.
iKapa Waterproofing and Roofing carries out invasive damp remediation, structural wall repairs, zinc and asbestos roof replacement, gutter and downpipe replacement, and exterior restoration in Woodstock, Salt River, Observatory, and surrounding areas.
What Invasive Damp Remediation Actually Means
Many damp problems in older Woodstock and Salt River properties have been treated repeatedly with surface products — waterproof paint, sealers, new plaster over old. These treatments haven't held because the underlying masonry was saturated and the source was never sealed.
Invasive remediation means removing what hasn't worked. Failed, soft, or salted plaster is cut out and removed. Saturated substrate is assessed and allowed to dry. The moisture source — whether penetrating damp through external render, rising damp through the masonry, or a combination — is correctly identified and sealed before any new plaster or coating is applied.
The result is a repair that addresses the actual condition of the wall rather than adding another layer over a failed one. This takes longer and costs more than surface treatment — but it holds.
Services We Carry Out in Woodstock, Salt River and Observatory
Invasive Damp Remediation
We remove failed plaster and saturated substrate, identify and seal the moisture source, allow the wall to dry correctly, and replaster with an appropriate render. Where rising damp is present and a damp proof course is absent or failed, we install a chemical injection damp proof course before replastering.
Zinc and Corrugated Roof Replacement
Corrugated zinc roofing on older Woodstock and Salt River properties corrodes over time — at fixing points, along ridges, and at junctions. We carry out full sheeting replacement, fixing replacement, ridge and flashing installation, and guttering on older zinc-roofed properties.
Asbestos Cement Roof Replacement
Where asbestos cement sheeting has deteriorated, we carry out compliant replacement with IBR or corrugated steel sheeting, including correct removal and disposal of the asbestos material.
Structural Wall and Plaster Repairs
Beyond damp remediation, we carry out structural wall repairs on older properties — repointing, crack repair, render replacement, and preparation for painting or waterproofing.
Gutter and Downpipe Replacement
Older gutters on Woodstock and Salt River properties are typically corroded mild steel or cast iron. We replace with modern aluminium or uPVC systems, correct the bracket spacing and fall, and ensure downpipes discharge correctly.

Frequently Asked Questions
Why doesn't waterproof paint fix damp in old Woodstock homes?
Older Woodstock properties typically have saturated masonry walls and failed original plaster. Waterproof paint applied over saturated or salted plaster creates a barrier that traps moisture behind it — the paint fails, the plaster deteriorates further, and the problem returns. Correct treatment requires removing the failed plaster, drying the wall, sealing the moisture source, and replastering with salt-resistant render.
Do you remove asbestos roofing?
Yes. We carry out asbestos cement sheeting removal following correct procedures and replace with IBR or corrugated steel sheeting. If you're unsure whether your roof contains asbestos, we can inspect and advise.
How long does invasive damp remediation take?
The remediation itself — plaster removal, drying, replastering — typically takes 1 to 3 weeks depending on the extent and the drying conditions. The wall needs to be genuinely dry before new plaster goes on, which cannot be rushed. We give a clear programme at assessment stage.
