Smart Renda

Smart Renda, operated by Smart Building Solutions Ltd, specialises in external wall insulation (EWI) for older solid-wall homes, particularly in London and surrounding areas. They focus on properties like Victorian and Edwardian houses that often lack wall cavities, leading to significant heat loss. The company emphasizes a thorough assessment process, starting with a free, no-pressure survey to diagnose issues and recommend suitable insulation and render systems.

Their installation process involves fixing insulation boards (EPS or mineral wool) to the exterior wall, followed by a reinforcing layer with mesh, and finished with a weatherproof render or board system. This not only improves thermal performance, leading to warmer rooms and reduced heat loss, but also refreshes the exterior appearance of the home. They highlight the importance of detailing around windows, sills, and eaves to ensure system performance and longevity, offering a 15-year manufacturer-backed system warranty.

Smart Renda prides itself on transparency, providing clear, written, fixed-scope quotes that detail the system, render type, scaffolding, and payment stages. They aim to explain any potential disruption upfront and manage the project through six defined steps, from survey to final inspection and aftercare. With over 24 years of combined experience in refurbishment and external finishes, they focus on providing honest advice, even advising against EWI when it's not the right solution for a property.
