Fineholm manage the flat about me which has a leak from their toilet which has come through the ceiling and into my bathroom causing water damage to my bathroom. The water is filthy and smells as it is toilet waste. It has damage wood panelling and the blind over my window. It took Fineholm 36 hours to get a plumber (Dynarod) out to their property. After they had 'conducted the repair' and left the water flow increased rather than stopped. We are now over 48 hours and still no repair and still the water flows through my ceiling. The agent I spoke to at Fineholm wasn't at all interested in the damage to my property, made out that it was my responsibility and had no sense of urgency. I would avoid using this company if I were a landlord or a tenant.
