We work with a range of high-quality putties and glazing sealants, selected to suit the age, condition and performance requirements of each window. Where traditional linseed oil putty is appropriate, we value its proven longevity and breathability; in other situations, carefully chosen modern sealants may be used to achieve the best long-term result. In all cases, materials are chosen to accommodate the natural movement of timber, provide a durable seal, and protect both glass and frame for many years to come.
