Prevent Water Ingress & Ensure Long-Lasting Window Seals
Leaking windows can cause serious structural damage, damp issues, and energy loss if left unaddressed. Water ingress often occurs due to failed window seals, deteriorating gaskets, or misaligned frames, leading to mould growth, interior damage, and costly repairs.
At Peak Access Abseilers London, we specialize in window leak detection and waterproofing, using advanced testing, sealing, and repair techniques to prevent water ingress and restore full weather protection. Whether your windows need new mastic seals, glazing adjustments, or full waterproofing solutions, we ensure long-term durability and compliance with BS 6262 glazing standards.

How Window Leaks Occur & Why Waterproofing is Essential
🔹 Failed Mastic & Sealant – Over time, UV exposure and weathering degrade window seals, allowing water to seep through.
🔹 Frame & Joint Movement – Structural shifts and vibrations can cause gaps between the glass and frame, leading to leaks.
🔹 Clogged Drainage Channels – Windows often have built-in drainage routes that can become blocked, causing water buildup and overflow.
🔹 Poor Window Installation – Incorrectly installed or aged glazing fails to provide a watertight seal, leading to long-term damp issues.
🔹 Extreme Weather Exposure – London’s rain, wind, and temperature fluctuations accelerate window wear, making regular waterproofing essential.
By sealing gaps, repairing frames, and replacing degraded seals, we help protect buildings from water damage and energy inefficiency.
