Services

External Wall Insulation

External Wall Insulation improves energy efficiency by reducing heat loss through solid walls. Our BBA-approved systems include thermal insulation boards covered with protective mesh and silicone-based renders. This solution lowers energy bills by up to one-third while enhancing property aesthetics and value. Available in thousands of colours, our systems include a 25-year insurance-backed warranty and qualify for government grants like the Green Homes Grant.

Domestic Rendering

Silicone-based rendering transforms property exteriors while providing weather resistance. We offer traditional sand/cement alternatives for listed buildings and modern finishes for new constructions. Our rendering services include surface preparation, crack repair, and decorative finishes. Projects range from single-wall repairs to full-house renovations, with options for lime-based renders in heritage projects.

Exterior Refurbishment

Comprehensive exterior refurbishment combines insulation, rendering, and architectural improvements. Services include gutter replacement, window cill extensions, fascia repairs, and feature stone restoration. We coordinate multiple trades to complete projects efficiently during primary scaffolding periods. Our team handles both functional repairs and aesthetic enhancements for residential and commercial properties.

Cladding Solutions

Modern cladding solutions enhance building durability and contemporary appeal. We install brick-effect renders, stone features, and aluminium sheeting for commercial properties. Our systems integrate with insulation requirements while meeting planning regulations. Projects include both decorative accents and full-building cladding replacements, with options for heritage-compatible materials.

Internal Insulation

Internal insulation provides energy efficiency where external work isn't possible. We install high-performance insulation boards with plaster or render finishes. This solution suits listed buildings and properties with appearance constraints. Our systems maintain internal space efficiency while improving thermal performance and reducing damp risks through vapour-permeable materials.
