The Question Every Homeowner Faces
Every home repair comes with a version of the same question: can I do this myself, or do I need to call someone? Get it right and you save money, develop skills, and gain confidence. Get it wrong and you face a bigger repair bill — or worse, a safety issue. Here's a clear framework for making the call.
Do It Yourself: Green Light Jobs
These are repairs that any capable adult can learn to do safely, with the right guidance and basic tools. No professional qualifications are required, and the risk of serious harm if done incorrectly is low.
- Fixing dripping taps and replacing washers
- Unblocking drains (sink, shower, bath)
- Fixing running or phantom-flushing toilets
- Re-caulking around baths, showers, and sinks
- Filling holes and cracks in walls and ceilings
- Sanding and repainting walls and woodwork
- Bleeding radiators
- Replacing door handles, hinges, and draught excluders
- Fixing squeaky floors and doors
- Hanging shelves, pictures, and mirrors
- Replacing tap washers and aerators
- Basic grouting and tile repair
Proceed with Caution: Medium-Risk Jobs
These jobs are doable for a more experienced DIYer but carry more risk — of causing damage, of getting it wrong in a way that creates future problems, or of personal injury. Approach these with research, patience, and honest self-assessment.
- Replacing a light switch or socket (always turn off the circuit and test with a voltage tester)
- Replacing a toilet cistern or internal mechanism
- Plastering a small area
- Laying floor tiles or vinyl
- Replacing a kitchen tap
- Basic timber repairs and carpentry
Always Call a Professional: Red Light Jobs
Some jobs carry risks of serious injury, legal liability, or harm to others if done incorrectly. These must be done by qualified professionals:
- Any gas work: boilers, gas pipes, gas appliances. Must be a Gas Safe registered engineer in the UK. Full stop.
- Structural work: removing walls (especially load-bearing), underpinning, loft conversions requiring structural calculations.
- Rewiring: full or partial rewiring requires a qualified electrician and may need to be inspected and certified.
- Main drainage and sewage: any work on the main soil stack or connection to the public sewer.
- Flat roofing and major structural roofwork.
- Any repair involving asbestos (common in pre-1990s UK homes).
The Test: Three Questions
Before attempting any repair, ask yourself:
- Can I find a reliable guide for this specific repair? If you can't find a clear, detailed how-to from a credible source, that's a sign the job may be more complex than it looks.
- What happens if I get it wrong? A poorly hung shelf falls over. A poorly plumbed gas connection can kill. The severity of the failure matters.
- Do I have the right tools? Improvising with wrong tools damages the work and the repair. If you don't own the tool and hiring it isn't feasible, factor that into the decision.
Knowing your limits isn't weakness — it's wisdom. And knowing what you can do is power.
