Correct Diagnosis, Professional Installation, Long-Term Protection
Damp Proof Course Installation in York
A damp proof course (DPC) is a critical barrier designed to prevent ground moisture rising through your walls. In many York properties, especially older homes, the original damp proof course may be damaged, bridged, or completely absent — leading to persistent low-level damp issues.
At Damps, we install damp proof courses only where they are genuinely required. Our focus is on accurate diagnosis, correct installation, and full reinstatement — not unnecessary treatments.
Damp Proof Courses in York Homes
York has a high proportion of Victorian and Edwardian housing, much of it built before modern damp-proofing standards were introduced. These properties typically feature:
In these situations, moisture can track up through the masonry if the damp proof course fails — particularly given York’s wet climate and higher-than-average rainfall.
A failed damp proof course is often blamed for damp problems — but in reality, this is not always the case.
Common Issues with Damp Proof Courses (and Misdiagnosis)
We regularly find issues caused by:
-
Bridged damp proof courses due to raised paths or driveways
-
Modern cement plasters trapping moisture
-
Blocked air bricks
-
External drainage problems
-
Penetrating damp mistaken for rising damp
Installing a new damp proof course without addressing these factors can be ineffective. That’s why diagnosis always comes first.

How We Assess the Need for a Damp Proof Course
Before recommending DPC installation, we carry out a full damp assessment to confirm whether it is necessary and appropriate.
Our inspection includes:
-
Visual checks internally and externally
-
Moisture profiling at different wall heights
-
Identification of salt contamination
-
Assessment of existing damp proof course position
-
Ground level and drainage checks
-
Ventilation assessment
This allows us to confirm whether a damp proof course is the correct solution — or whether another treatment would be more effective.
When a new damp proof course is required, we select the method based on the property’s construction and condition.
Damp Proof Course Installation Options
Chemical Damp Proof Course (Injection)
This is the most common solution for many York homes. A specialist damp-proofing cream is injected into the mortar bed to form a new moisture-resistant barrier once cured.
Physical Damp Proof Course Systems
In certain situations — such as severe contamination or solid wall construction — alternative damp-proof membrane systems may be recommended.
We’ll always explain:
-
Why a particular system is suitable
-
How it works
-
What results you can expect
No generic solutions, no shortcuts.
Plastering and Wall Finishes After DPC Installation
Installing a damp proof course alone is not enough. The surrounding plaster is often contaminated with salts and must be dealt with correctly.
Our reinstatement process typically includes:
-
Removal of affected plaster to the correct height
-
Application of salt-resistant or breathable plaster systems
-
Lime-based renovation plaster (such as Limelite) where appropriate
-
Replacement of skirting boards if required
-
Clean, professional finish ready for decoration
Because we handle both the damp proof course installation and the plastering, the entire process is controlled from start to finish.
