Facade Waterproofing & Leak Repair
Facade leakage is the most common complaint reported by building owners and facility managers in India. Fine Glaze specialises in facade waterproofing, leak diagnosis, and sealant remediation for curtain walls, structural glazing, ACP cladding, and aluminium window systems.
Why Facade Leakage Happens — and How to Fix It
Water ingress through building facades causes significant damage to interiors, false ceilings, MEP installations, and even structural steel. In India's high-rainfall climate — particularly in Mumbai (2,400mm/year) and Pune (700mm/year) — facade waterproofing is essential.
Common Causes of Facade Leakage in India
- Failed silicone sealant joints: Silicone degrades after 10-15 years due to UV exposure, thermal cycling, and building movement. Cracked or debonded sealant is the number-one cause of facade leakage.
- Improper original installation: Inadequate joint depth, wrong sealant type, or contaminated surfaces at installation lead to premature sealant failure.
- Thermal movement fatigue: Building facades expand and contract with temperature. Joints that are too narrow or stiff crack over time.
- Missing or failed drainage channels: Curtain wall systems rely on internal pressure-equalisation drainage. Blocked drainage directs water inward.
- Glass seal failure: DGU units lose their edge seal allowing inter-pane condensation.
Fine Glaze Waterproofing Repair Process
Fine Glaze uses a systematic approach: (1) Hose test diagnosis per AAMA 501.2 to locate all active leak points; (2) Core sampling of sealant joints to assess adhesion; (3) Detailed remediation specification; (4) Sealant removal and surface preparation; (5) New sealant application using Dow Corning, Sika, or Master Builders products; (6) Post-remediation water test to verify 100% water-tightness before sign-off.
Fine Glaze offers AMC-based facade waterproofing programmes that include annual inspection of all sealant joints, pre-monsoon repair of any deteriorating sealant, and priority callout response for active leaks during the monsoon season. Proactive AMC programmes significantly reduce the risk of interior water damage and extend facade sealant life.

Frequently Asked Questions
How much does facade leak repair cost in India?
Facade sealant remediation costs Rs 150-400 per running metre for standard joint re-sealing, depending on joint depth, access difficulty, and sealant specification. A comprehensive waterproofing programme for a 10-storey building typically costs Rs 5-20 lakh.
How often should facade sealant be replaced in India?
Silicone facade sealants typically last 15-20 years under normal conditions. In coastal Mumbai, 10-12 years is more realistic. For Pune buildings, a full sealant inspection every 7-10 years with replacement as needed is recommended.
Can Fine Glaze repair leaking curtain wall in an occupied building?
Yes. Fine Glaze regularly performs curtain wall sealant repair in occupied buildings. Our team uses low-odour, fast-curing sealants, works in section-by-section sequence to minimise disruption, and can schedule critical work in evenings or weekends to avoid business disruption.
