What our Clients say
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.
Owner's reply
Hi Stuart, Thank you for your kind words and for trusting DS Projects to fix the leak in your car park slab. We're glad you're happy with the results! Choosing the right solution can make all the difference, and we're pleased to hear you'll consider this method in the future. If you ever need assistance again, feel free to reach out. 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!
