Geoff was extremely helpful and professional, he came out to look at the issue I had with a damp wall promptly. He diagnosed the problem and within a few days was able to rectify the root cause by injecting a DPC and plastering the wall. The price was very competitive and Geoff was extremely knowledgeable about the problem and how to fix. There was no mess left afterwards and follow up aftercare was really good. Excellent service all round, very friendly and would highly recommend!

We highly recommend Preservit. Geoff came and surveyed our rising damp issue (no charge for this) and clearly explained what was needed. He kept in regular touch regarding times and dates and always arrived as arranged. The work was carried out in as unobtrusive a way as possible with care and attention to tidiness and minimising of mess. We are very pleased with the quality of the work and highly recommend you give Geoff a call.

To restrict the damage, our experts replace defective timber and undertake repairs where necessary to ensure optimal structural strength and stability.
