Central heating system leakNorthwood, North London

We had a on going leak on our central heating system for months no one could find it until Miracle Leak Detection came. Their work was exemplary and the technician spent three days trying everything before eventually finding a small leak underneath our house. How he found it I don’t know but he was fantastic. He had to cut a hole in our porcelain tiles which was neat and tidy. He repaired the damage. Now I can relax.
