The short answer
Before any contractor touches the facade, walk it, photograph every existing defect with its location, record it in writing, and have both sides acknowledge the record. Do it again after the work.
When to do it
- Before a post-construction final clean
- Before restoration work
- Before a new window cleaning or washing contractor starts
- Before work at height that could affect the facade
- At acquisition or turnover
What to photograph
- Each elevation, wide, so locations are clear
- Close-ups of every defect, with a reference for scale
- Scratches, etching, staining, chips and cracks in glass
- Exposed coating damage, which shows as a change in reflection
- Oxidation, pitting and coating failure on metal
- Cracks, staining and failed joints on the facade
Photograph with even light where possible. Some glass damage only shows at an angle.
What to record
| Field | Example |
|---|---|
| Location | North elevation, floor 3, pane 12 |
| Surface | Glass, heat-treated, exposed coating |
| Defect | Scratches, approx. 6 in, horizontal |
| Photo reference | IMG_0412, IMG_0413 |
| Date and recorded by | Name and company |
Illustrative. Use whatever format both parties will sign.
Make it count
- Walk it jointly with the contractor or general contractor
- Have both sides sign or acknowledge the record
- Keep originals with dates intact
- Repeat after the work, with matching photos
How S&K works
S&K assesses glass and metal before restoration, scopes the work in writing and documents before and after. Get the glass and metal damage triage guide for a field checklist, or request a quote for an assessment.
