What this work involves
Assess wall construction, moisture and suitability. Include window reveals, ventilation and adjacent building elements.
- Internal, external or cavity approach
- Window and floor junctions
- Facade appearance and internal space
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Detail moisture-sensitive timber, facade and frame junctions for inspection.
What the drawing needs to explain
Create a defect map with photographs, locations and investigation questions. Include inspection access and the intended drainage path in the repair proposal.
Allow for later maintenance
Use the defect map for later checks. Compare photographs of the same locations so changes are not assessed from memory alone.
Which trade-off matters?
Completely concealing a junction may look attractive but make later inspection harder. Compare a closed finish with a solution keeping vulnerable points accessible.
Cost factors for this service
Costs depend on wall build-up, access, investigation and final finishes. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for external wall & cavity insulation. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging external wall & cavity insulation?
A cavity is not automatically suitable for filling. Prior investigation determines an appropriate approach for the wall and surroundings.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
