Core offering

Masterdec Ltd. manufactures custom fire-rated doors (FD30 and FD60 ratings) at its London facility, and provides complementary passive fire protection, decoration, and carpentry services. The company serves construction contractors, housing associations, local authorities, and commercial clients across the UK, supplying complete fire door sets, fire stopping installations, painting/decorating, and bespoke carpentry work with strict quality and safety standards.

Product overview

Masterdec Ltd. operates as a single-product-service company offering four interconnected service lines: (1) Fire Doors — their primary manufactured product line featuring FD30 and FD60 rated doorsets in multiple designs (DR-01 through DR-03 series), all produced in their London facility; (2) Passive Fire Protection — complementary fire stopping services including penetration sealing, intumescent coatings, and cavity barriers that work alongside their fire door products for complete building compartmentation; (3) Decoration — painting and decorating services for interiors and exteriors, including fire-retardant coatings; and (4) Carpentry — bespoke woodwork and fire door installation/maintenance services. The fire doors serve as the core manufactured product, while passive fire protection, decoration, and carpentry represent service offerings that often accompany fire door installation or complement fire safety compliance requirements.
