What this work involves
Cracks and movement can have several causes. Gather existing information and arrange assessment before choosing a repair method. Consider the transition between an existing building and an extension.
- Existing drawings and foundation information
- Damage or new load assessment
- Ground and structural information
- Suitable methods
- Monitoring and completion records
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Show how new structural elements connect without unnecessarily removing valued details.
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.
Decide this before construction
Photograph retained details before dismantling. Check the dimensions of new components against the actual facade before production begins.
Cost factors for this service
Investigations, access, method and scale determine the cost. Floor area alone is usually insufficient for a reliable estimate.
Bring this to the discussion
Damage photographs, building age, earlier reports and plans.
Questions about the work
Does every crack mean foundation failure?
No. Cracks can have other causes. Their nature, development and relationship should be assessed before drawing conclusions.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
