PROFESSIONAL LEAK DETECTION ACROSS CORNWALL

Water travels in mysterious ways through buildings. A damp patch appearing on your bedroom ceiling may originate from a roof defect metres away, having tracked along rafters, across membranes, and through multiple junctions before finally becoming visible. Simply repairing the obvious damp location rarely solves the underlying problem. Effective leak repair requires first identifying the actual water entry point, which can prove surprisingly difficult.

Many homeowners spend years addressing recurring damp without ever solving the underlying cause. Multiple repair attempts that fail to stop the problem waste money and cause frustration. Meanwhile, hidden water continues damaging building fabric, creating far more serious problems than the visible damp suggests. Proper leak detection breaks this cycle by identifying genuine causes rather than treating symptoms.

JB Contractors provides systematic leak detection services across Plymouth, Truro, Newquay, and throughout Cornwall. We investigate problematic leaks that have defied previous repair attempts, applying methodical approaches to identify actual water entry points. Once we know where water enters, we can implement repairs that genuinely solve the problem.

WHY CHOOSE JB CONTRACTORS

Systematic Investigation: Effective leak detection requires methodical examination rather than guesswork. We trace water damage back from visible manifestations, examining the building structure to understand how water could travel from potential entry points to where it appears. This often reveals possibilities that would not be obvious from surface inspection alone.

External Examination: Thorough roof inspection identifies potential water entry points. We check all flashings, valleys, ridge and hip details, penetrations for pipes and aerials, and the general condition of the roof covering. We examine walls above the damp area for rendering faults or pointing failures. Gutters and downpipes are checked for leaks and overflows.

Testing: Sometimes the only way to identify leak sources is controlled water testing. We apply water to suspected areas systematically while monitoring for penetration internally. This eliminates possibilities and confirms actual entry points that might otherwise remain speculative.

Comprehensive Solutions: Once we identify where water enters, we implement effective repairs. This might involve roof repairs, new flashings, chimney work, or addressing issues with walls or windows. We solve the actual problem rather than applying temporary patches that fail again.
