Richard Brown Plastering Contractors delivered expert PermaRock Mineral Fibre EWI and rendering for the St Mary’s Hospital extension in the Isles of Scilly. The project provided modern, energy-efficient facilities to meet the island’s healthcare needs. As approved EWI and rendering specialists, the team ensured a high-quality, durable finish throughout.

Here’s the full details of the case study and how we were involved in this restoration project.

About the Project

Using PermaRock EWI Systems

As approved PermaRock applicators, Richard Brown Plastering Contractors installed the PermaRock Mineral Fibre External Wall Insulation (EWI) System on this project. The mineral fibre system delivers excellent thermal insulation, fire performance and weather resistance, creating a safe and energy-efficient exterior. Its non-combustible and highly breathable design makes it ideal for coastal environments, where durability and moisture control are essential.

This PermaRock system provides long-term protection and a clean, durable rendered finish that enhances the building’s appearance and performance. As experienced EWI contractors, Richard Brown Plastering Contractors ensure every installation meets the highest standards, combining skilled workmanship with systems designed for modern energy efficiency and sustainability.

After waiting two years for another contractor to 'not' start our EWI, Richard Brown Plastering were able to start within a month of providing a competitive quote. Dealing with Andrius was a pleasure and he was thorough and responsive in planning the job and adjusting for any issues along the way. The job was carried out quickly and efficiently and the end result was excellent.

Richard Brown Plastering made a brilliant finish to our bungalow. We had problems with damp penetrating through old pebble dash and Richard advised on external insulation which we are pleased to say has worked a treat with no damp coming through and the finish looks really really smart. Richard’s workers were extremely professional, very quick and tidy. We are very pleased with the finish and would recommend Richard, Andrius and his workforce.

Absolutely incredible! Our house needed urgent renovation and new rendering to prevent from condensation causing dampness in the house. I was looking for house insulation with silicone render. After questioning many contractors, it was clear that Richard and his team were true professionals in their field with years of experience. I was given genuine advice and couldn’t ask for better customer service. Entire project was greatly executed and Richard and Team went always above and beyond if I needed help or additional alterations. Andrius was always to hand if I had any queries and everyone in the team executed their work with a smile. As a result of their incredible work, we have now well insulated and beautifully looking house. If you’re looking for professional and reliable service with people who pride themselves in delivering great work, look not further.

Fabulous company! They fitted external wall insulation to my huge end-of-terrace gable wall and kitchen, and it has made such a difference. I have nothing but praise for the project management, quality of the work, attention to every single detail, colour match of the render, tidiness and clearing-up, as well as the quality assurance as the job progressed. Everyone on the job was so friendly and nothing was too much trouble. Just a word of advice… This work is very weather-dependent; it is not going to happen the week after next. Be patient, because Richard and his team are absolutely worth waiting for. I have already asked them back to do a further job. Update.... And the magical team returned to re-render the old wall adjacent to the EWI they had done. This was a job with some nasty surprises in the brickwork underneath the old render but the finished work is superb. Once again, communications, quality assurance, workmanship and immaculate clearing-up were all 5-star. (And they power-washed the steps, too, without being asked!) The cost was so reasonable, even taking into account the terrible state of the failing brickwork, which revealed itself as work began. I cannot recommend this company highly enough. It is faultless.
