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.
Compare profile sizes and joints in a sample detail beside the existing facade.
What the drawing needs to explain
Draw a scaled elevation showing existing and new windows together. Resolve the roof-edge, wall and window junction before deciding from an atmosphere image alone.
Allow for later maintenance
Record which elements are new, repaired or retained. This distinction helps identify the appropriate finish and maintenance method for each material later.
Which trade-off matters?
Exact reproduction and a clearly contemporary addition are different design choices. Compare their junctions; an almost matching brick or profile can look less coherent than a carefully chosen contrast.
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.
