What this work involves
Record location, timing and conditions. Distinguish possible leakage, condensation and building-related causes.
- Investigation and measurements
- Source correction
- Drying and finish repairs
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Investigate whether moisture traces near the glazing originate indoors or outdoors.
Decide this before construction
Fix the kitchen layout and finished floor levels before ordering services and glazing. Plan the outdoor transition too, even when garden work will follow later.
Allow for later maintenance
Keep glazing and rooflight maintenance instructions together. Leave outdoor surfaces accessible without having to remove permanent furniture or planting.
How to review the result
At completion, walk from the cooking area to the terrace. Check the opening with the intended furniture in place and review the light with any shading closed.
Cost factors for this service
Costs depend on investigation scope, cause, access and reinstatement. 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 damp investigation & treatment. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging damp investigation & treatment?
Address the moisture source first. New paint or cladding does not replace a supported diagnosis.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
