Timber Cladding Investigation at Fox Steep
The Problem
The client instructed H+R to undertake a detailed investigation of the Elm cladding of this building in Oxfordshire and the accompanying pool house within the grounds. For QS purposes, information was needed regarding the total quantity of Elm required to undertake repairs. This survey was in conjunction with a preliminary stage 1 investigation of the building which included an initial condition assessment of joinery and structural timber elements, roof finishes, roof drainage, the masonry substrate, ground and surface drainage, and chimneys.
The Solution
A detailed visual and physical examination of the timber cladding was undertaken, identifying a variety of defects including vertical alignment of board ends allowing moisture to penetrate to the masonry substrate, significant plant growth behind the timber rainscreen forcing boards off battens and causing localised issues with damp and decay, widespread use of inappropriate materials such as impermeable sealants, and issues with defective roof drainage resulting in saturation of boards and subsequent structural decay.
The subsequent report included an extensive list of recommendations and guidance to follow when replacing or repairing the boards identified as defective at the time of survey. Defects were also highlighted on attached CAD overlays, and photographic evidence compiled, covering all elevations enabling accurate costings to be prepared prior to refurbishment.
