What our Clients say
Paul2025-05-02Trustindex verifies that the original source of the review is Google. What an awesome team. Thanks Eoin for fixing a long time water leak. Thanks Brad for being super reliable and respecting our space. Your preparation and cleanliness throughout the process was second to none. Job well done, Highly recommend! Steven Taing2025-04-03Trustindex verifies that the original source of the review is Google. We had a water leak at the roof level due to a heavy rain event, which led to water ingress into the lift shaft. The team at DS Projects, including Eoin, Brad, and the rest of the crew, responded quickly and professionally. They conducted a comprehensive water test to pinpoint the exact source of the leak and worked diligently to resolve the issue. Their expertise and commitment to quality were evident throughout the process, and as a result, we have engaged them to remediate several other concrete and waterproofing issues in the building. We highly recommend DS Projects for their reliability, problem-solving skills, and exceptional workmanship! Will Edwards2025-03-20Trustindex verifies that the original source of the review is Google. Great company with fantastic results Toby Ginn2025-03-19Trustindex verifies that the original source of the review is Google. The DS team were great from the initial contact to final completion. Highly recommended!! Stuart Mclean2025-02-16Trustindex verifies that the original source of the review is Google. We used DS Projects to fix a leak in our carpark slab, very happy with the results and will certainly consider this method over installing drip trays in the future. Corrine McKenna2025-01-08Trustindex verifies that the original source of the review is Google. Eoin, Brad, and the team came to resolve a long-standing strata issue that had been ignored for nearly a year. Water was entering my son's bedroom through missing lead flashing, causing black mold – a serious risk for a child with asthma. From the moment Eoin assessed the situation, he provided all the information I needed, which made me feel confident in paying for the solution to permanently fix the problem. The work has now been completed, and the room is no longer leaking, even after heavy rainfall. Additional water tests have shown everything is dry. The onsite team was friendly, respectful, fast, and efficient, even going the extra mile to clean up the rooms and hallway – you'd never know they had been there. With a 25-year guarantee, excellent craftsmanship, and professionalism, I couldn't recommend them more. I sleep easier knowing my children now have a safe place to sleep. Thank you! Juan Leon2024-12-30Trustindex verifies that the original source of the review is Google. Good support, prompt reply to any enquiries.
