Story

TrueLine Ltd was launched in July 2025 when Krystian Chlasta took over the Channel Islands dealership for Timber Windows from Bonsai Group, after leading the Timber Windows portfolio there for three years. Bonsai Group founder Mat Rolfe retained a shareholding and advisory role for a 12-month transition period. Existing Timber Windows warranties transferred across and are fully honoured.
