External & Envelope Works

WHL Projects undertakes the full spectrum of external and façade works, from complete recladding and render replacement to traditional masonry restoration. We deliver projects for commercial, industrial and public-sector clients across the UK where compliance, weather performance and visual impact are equally critical.

Scope of works

Our capability covers every major envelope discipline:

• Cladding replacement and façade upgrades – rainscreen, metal cassette, composite and insulated render systems.
• Curtain walling and glazing – stick and unitised systems, including spandrel and solar-control glass.
• Masonry restoration – brick and stone cleaning, repointing, and structural façade stitching.
• Render and external insulation systems – polymer, silicone and through-colour renders with integrated insulation boards.
• Building sealing and weatherproofing – expansion joints, mastic works and liquid-applied coatings.
• Roof-to-wall interface detailing – parapet flashings, copings and verge terminations ensuring continuous protection.

Each project begins with a detailed survey of the existing façade, identifying fire-stopping, thermal and structural deficiencies. We then design coordinated packages with manufacturers to guarantee compatibility across systems.
