Handymen carry out small repairs, maintenance and improvement jobs in homes and other properties. The work may include assembling flat-pack furniture, fitting shelves and curtain poles, adjusting doors and handles, replacing locks or hinges, repairing minor damage to walls and woodwork, and putting up pictures or mirrors. Some also undertake basic decorating, such as painting a room or touching up surfaces. Services vary by business and by the skills and equipment available. A handyman may also help with simple outdoor maintenance, such as fixing a gate, clearing gutters or making minor repairs to a shed. Customers usually agree the tasks and materials in advance, and work may be offered as a one-off visit or a set of small jobs. Electrical work, gas work and certain plumbing or building tasks can require specialist qualifications or approval, so these jobs may need to be carried out by an appropriately qualified tradesperson instead.
