Why Mastic Sealing Matters
Mastic sealing is essential for protecting buildings from moisture, air leakage, and structural movement. Proper sealant application:
- Prevents water ingress and damp issues
- Improves energy efficiency by reducing air leakage
- Provides flexibility for structural movement
- Enhances durability of windows, doors, and building façades
- Ensures clean, professional visual finishes
At GP Contracts, we use high-performance sealants and industry best practices to deliver a finish that is both functional and long-lasting.
