Portglenone First Presbyterian Church is a Grade B listed nineteenth-century church with basalt walling and natural slate roofing. The main church is rectangular on plan with hipped slate-roofed 26 metre high tower located on its north-west corner. In 2011 The Congregational Church Committee appointed Alastair Coey Architects to prepare a condition report of the church to provide an assessment of the condition of the existing building fabric to facilitate the church in devising a programme of repair and restoration. A contract for refurbishment of the main church building commenced in September 2013. Work to the main body of the church included internal and external refurbishment. Internally, the church underwent complete refurbishment including remodelling to include a new disabled access WC, new damp-proofing and plasterwork throughout, new electrical installations and complete re-decoration. External work included upgrading of the roof and ceiling insulation, installation of refurbished copper ventilation turrets, new lead-work, re-slating using existing slates to east elevation and new slating to west, to match existing. Existing ridge tiles were reused where possible and a new lightning conductor installed and commissioned to the main roof and tower. Work to the church tower included high and low-level masonry repairs; removal of vegetation from masonry including biocide treatment; installation of new cresting which had been removed at the time of earlier work to the tower, and replacement timber louvres to prevent water ingress to the tower interior. During the building contract, the church congregation relocated to the adjoining church hall, and as such the main car-park and part of the building had to remain in-use during the contract. This was carefully managed and co-ordinated and has now been successfully handed over to the church on completion. The contract was 18 months and was completed in April 2015.
