10 Rising Damp
Posted 11 May
We're really pleased that we decided to use Trident Damp Ltd
We were extremely pleased with the work carried out by Trident. Joseph replied quickly when we first got in touch and gave us very helpful advice. He responded to all my emails. When the team came to do the work they were polite, helpful and professional. They worked hard and cleared everything away before they left. Joseph also followed up once the work was completed and issued a 20 year guarantee. I would be very happy to recommend Trident to others that may need damp work to be carried out.Verified reviewerJob location: SE910 Damp Survey

Damp survey
Joseph from Trident carried out a pre-purchase damp survey for us today. He was thorough, honest and transparent about the costs, and more reasonable than other quotes we’ve received. Would definitely recommend.Verified reviewerJob location: SE1410 Rising Damp

Fantastic service from start to finish
Came to sort out a rising damp issue in our property - Joseph attended our property free of charge to take a look which was so nice. We were quoted more from another larger company and Joseph's price was the best so decided to go with Trident. Joseph and his team arrived on the day on-time and were absolutely brilliant - real attention to detail, tidy, efficient and just genuinely nice people. Would deffo recommend! Thanks Trident :)Job location: DA110 Damp Survey

Pre Purchase Damp Survey
Joseph completed a pre purchase damp survey for a property we’re buying. The report was thorough, clear, and provided quotes for the remedial work and a site plan, plus further recommendations in other areas (such as getting a roofer and plumber in to look at other issues). The report was provided the same day as the survey, and gave us everything we needed to help negotiations with the vendor. 5 star service, thank you!Verified reviewerJob location: DA5RAlice PResponse from Trident Damp Ltd

Amazing service with a knowledgeable and friendly team
Trident provided the perfect service to help with the damp issue at my house. They came round to inspect the issues and decided the best plan of action. They then consulted with me to decide what was necessary immediately and what could be addressed later down the line. The work was pretty extensive however the team carried it out speedily and efficiently and walked me through every stage of the process. I would 100% recommend, trustworthy & knowledgeable on all fronts.Verified reviewerJob location: SE23Response from Trident Damp Ltd
