Cob and Stone Round House Repairs Cornwall

We would highly recommend the services offered by Leslie Cornell. When our cob and stone roundhouse developed cracks and required attention, we looked for a specialist who could repair the structure and ensure it would withstand the elements for years to come. Leslie visited and shared his considerable knowledge, providing friendly advice and a comprehensive quotation.

His team arrived on site and shared the same passion for cob and stone that Leslie had shown. The work was completed in a professional and friendly manner and they were the tidiest trades people we have encountered. 

Thank you, Leslie and team.

Insulating Lime Render Cornwall

We first heard about Leslie Cornell Building Restoration Ltd by word of mouth. We were due to renovate a listed building that would be our home and so we wanted a professional and trustworthy team to complete the work for us. We wanted outstanding workmanship and we found it with Leslie and his team.

We contacted Leslie and made arrangements for him to come out to look at our property to discuss what needed to be done. He knows all about restoring properties, just like ours, which came across during his first visit. He explained to us the different options that were available and after the appointment he sent across a clear and coherent breakdown of costs.

We had no hesitation instructing Leslie and his team to carry out the work at our property. On the start date of the job, the team arrived promptly and parked their vehicles respectfully. Leslie greeted us and introduced the team and then ran through the job with his team, after which they remained busy for the duration of the job. Clearly, Leslie has high expectations and they all know the standard he expects. They all have a great knowledge and skill and each member of the team carried out work to a high standard, whilst leaving the work space clean and tidy and ready for the next day.

At the end of the job the team cleaned the area before leaving. They made sure to speak to us before they left. They made us aware that during the drying process the Lime may crack in places and to contact Leslie if we needed them to return and repair any areas. We did need them to return and they did so with immediate effect and rectified these small areas. Again, we were impressed with the level of care and professionalism the company have.

Overall, we have had a 5-star experience with Leslie Cornell Building Restoration Ltd and would not hesitate to recommend them to others. We are going to instruct them to carry out further restoration at our property in the future.

Lime rendering and Mineral Paint System St Agnes Cornwall

I am absolutely delighted with the work that Leslie Cornell carried out on my property in 2020. From the initial enquiry to the end of the project Leslie, Chris and the team were amazing. With an extensive knowledge for restoring the render on an old property like mine, it was obvious from the start that they enjoyed working with the building.

The team were very professional, cleaned up at the end of each day and made the whole process much easier than I had anticipated, I hardly knew they were there.

The end result is stunning and I would have no hesitation in recommending them to anyone looking for the same service.

Lime Pointing Bodmin Cornwall

We were recommended to approach Leslie Cornell Building Restoration after a good deal of our house restoration had already been completed. We had had the house re-roofed, electrically re-wired, a central heating system installed and a good deal of general building work completed. The house had suffered from decades of trapped moisture caused through a lack of heat and ventilation but primarily because the original lime mortar, when it had failed years earlier, had been replaced with cement then further exacerbated by the coating of a non-breathable render and white paint. The task of rectifying this problem seemed like a mountain to climb. From our very first meeting with Leslie he patiently listened to our concerns and quickly put us at ease with his passion and knowledge for the skills required in dealing with stone-built properties. We were provided with a detailed costed breakdown of the work phases involved and made certain we understood the processes involved, which add to our confidence that we were in good hands.

The actual work phase was far less daunting than we had imagined, given that the house had to be stripped back to bare stone and all the old cement joints removed before the new lime mortar could be applied. Leslie has instilled a very strong knowledge base and work ethic across his entire team, who were always polite and worked conscientiously throughout the day – they were a joy to have around. Their care, attention to detail and respect shown to our property was a real breath of fresh air. At the end of the day either Leslie, or the senior member of his staff, would ask us to inspect the work completed that day and make certain we were happy with the tidiness of the whole site before leaving.

Leslie and his team have transformed the exterior of our house and returned it to its original 200 year old look – it is now absolutely stunning! Leslie and his team have restored our faith in Cornish builders and we would have no hesitation in recommending them in future – thank you all.

Cornish Lime Company

We've worked with Leslie Cornell Building Restoration Ltd for many years now and are delighted to supply them with their Lime and associated products.

Over the last few years we have spent time with Leslie and his Team at the Royal Cornwall Show where we both exhibit, and, despite supplying them with lots of materials throughout the year it's only at this event that we really get to see the evidence and better appreciate what they do, and do very well indeed.  We hope we'll meet again at this year's Show in June in the Countrywide Skills Area, where we will see what they have been up to over the last year.
Their speciality is for Cob buildings and we wholeheartedly congratulate them for the sterling works they have carried out over the years.  We applaud their passion and focus on this very traditional material that may appear simple to many, but Leslie and his Team, like Cornish Lime, know and appreciate the consequences of what can go wrong when even simple materials are treated inappropriately.  Leslie Cornell Building Restoration Ltd are Specialists in this area and we look forward to supplying them with materials and assisting in their future.
