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.
Combine envelope repairs with an assessment of comfort improvements.
What the drawing needs to explain
Create a phase drawing with three colours: repair now, improve later and investigate first. Mark where phases meet, such as roof edges, service routes and finished floors.
Allow for later maintenance
Update the maintenance record after each phase. Keep photographs of concealed elements and note which investigation questions remain open.
Which trade-off matters?
A complete approach can improve coordination, while phased work spreads the budget. Compare which junctions would need reworking after a delay and which elements can be completed independently.
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.
