Portland Staircase Structural Repairs

MGS Restoration Ltd has extensive experience delivering structural repairs to Portland stone staircases. Working in close collaboration with main contractors and structural surveyors, we carry out all remedial works with precision, adhering to professional specifications and exceeding minimum compliance requirements to ensure long-term structural stability.

These interventions are typically performed during major construction phases, with staircases fully supported using Acrow props or equivalent temporary works systems. Our restoration processes commonly include the installation of stainless-steel dog cramps across fractured landings, injection of specialist liquid stone adhesives followed by colour-matched filler, targeted crack repairs to treads and risers, reconstruction of damaged nosings resulting from historical lift installations, and repointing using a lime-based Portland stone dust mortar for a durable and sympathetic finish.
