10 Fire Wall Installation
Posted 02 December
Job location: SO18Jason and his team were very helpful and professional when dealing with installing a fire wall in our loft space. Jason came round to do a quote and explained what was wrong and how they would be able to fix it. He put our minds at ease as we were worried it would be a problem that we wouldn’t be able to fix. We were booked in within a week of confirming the works and they did an amazing job as it was a confined space to work in. Everyone we dealt with were so friendly and also cleaned our stairs for us when they had finished the job. We will definitely use them again and would recommend them 10 A good job done

I recently hired DampMaster Portsmouth to resolve rising damp in my living room and was thoroughly impressed. From the start, their customer service was prompt, polite, and professional. The technician quickly identified the issue, explained the solution clearly, and provided a fair, no-pressure quote. The team was punctual, tidy, and respectful throughout the process, completing the damp-proofing on schedule and leaving the space spotless. Their attention to detail and clear communication stood out. Months later, the damp is completely gone—no mould, no odours—and the walls remain dry.Verified reviewerJob location: PO1210 Pre Purchase Damp & Timber Survey

I used DampMaster Southampton and Portsmouth for a pre-purchase damp and timber survey and was really impressed. Booking was easy, communication was clear, and the surveyor was professional and knowledgeable. The report was detailed, delivered quickly, and gave me a clear understanding of the property’s condition—no pushy upselling, just honest advice. I’d happily recommend them to anyone needing a reliable survey.Verified reviewerJob location: SO3010 Mould Survey Completed
