Looking for an experienced tradesperson to complete three jobs: 1. Repair and securely refix a radiator wall bracket. The radiator is currently disconnected and removed. One of the existing brackets is extremely loose, with damaged/crumbling plaster and an enlarged fixing hole. The bracket needs to be securely anchored into the underlying wall in its existing position, as the radiator and pipework cannot be repositioned. This may require repairing the fixing holes or using alternative suitable fixings. Photo attached. 2. Install a Roman blind cord cleat on a bedroom wall (masonry). 3. Mount a smoke detector (may also be masonry). The radiator bracket is the main priority. Please only respond if you have experience repairing failed wall fixings and drilling into hard masonry, and can assess the appropriate repair methods and materials.
