What this work involves
Review proportions, sightlines, operation and maintenance. Coordinate frames and glazing with insulation, internal finishes and existing sills. Changing an opening can require structural work.
- Frame material and profile
- Glazing, ventilation and shading
- Arrangement and opening direction
- Weather and airtight connections
- Internal and external repairs
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
Dimensions, glazing, material, fittings and installation influence the budget.
Bring this to the discussion
Photographs, approximate measurements and preferences for material and operation.
Questions about the work
Is finishing around the frame included?
Ask for window boards, lining, painting, plaster repairs and disposal of old frames to be specified.
