Silicone weather seals on a Dubai facade typically deliver 12 to 15 years before UV and thermal cycling exhaust their elasticity. Cheaper acrylic or hybrid seals fail far sooner.
The early indicators are visible from a rope-access inspection long before any interior symptom: surface crazing, chalking, loss of gloss, and hairline adhesion loss at the bond faces.
Once water reaches the transom drainage and gasket layer it begins corroding fixings and staining internal finishes — and the remedial cost multiplies.
We survey by zone, record adhesion test results per elevation and phase replacement so the building stays occupied throughout the works.
