Diagnosing, planning and knowing which jobs need a professional. Below are 7 copy-ready prompts. Fill in the [BRACKETS], copy, and paste into ChatGPT, Claude, Gemini or any capable assistant.
AI is a useful first opinion on a household problem and a bad final one, particularly where gas, electricity, water or structure are involved.
The 7 prompts
Work out whether to fix it yourself or call someone
Decide if a household job is within your ability.
Help me decide whether to do this job myself. THE JOB: [WHAT NEEDS DOING] MY EXPERIENCE: [what you have done before, honestly] TOOLS I HAVE: [WHAT YOU OWN] TIME AVAILABLE: [HOW LONG] WHAT IT WOULD COST TO GET SOMEONE IN: [QUOTE OR ESTIMATE, if you have one] MY SITUATION: [own the property / renting / leasehold] WHAT I AM WORRIED ABOUT: [YOUR CONCERN] Produce: 1. THE SAFETY GATE first. Some jobs should not be done by an untrained person regardless of confidence, because the failure mode is serious: anything involving gas, most electrical work beyond replacing a fitting, structural elements, asbestos in older properties, work at significant height, and anything affecting drainage or the water supply shared with others. Say plainly whether this job is one of them. If it is, stop there. 2. THE LEGAL AND REGULATORY CHECK - some work requires certification, notification or building control approval, and doing it yourself can cause problems with insurance or when selling. Say what applies and that it should be verified locally, since rules vary by country. 3. THE RENTING OR LEASEHOLD CHECK - if I said I rent or hold a lease, whether this is my responsibility at all, and what I should not touch. 4. WHAT THE JOB ACTUALLY INVOLVES - step by step, so I can judge it honestly rather than from the version in my head. 5. THE SKILL AND TOOL REQUIREMENTS - what is needed, and whether what I have is sufficient. Include tools that would need buying or hiring, and their cost, because that changes the arithmetic. 6. THE REALISTIC TIME - for someone at my stated experience level, which is longer than for a professional, and longer than the internet suggests. 7. WHAT GOES WRONG - the common mistakes on this job, and for each: whether it is recoverable, and what it costs if not. This is the key consideration. A job where a mistake means starting again is different from one where a mistake means a flood. 8. THE HONEST COMPARISON - against my stated quote: the cost of materials and tools, the time, the risk, and the likely quality difference. Sometimes the saving is small and the risk is not. 9. THE MIDDLE OPTIONS - doing the preparation yourself and having the skilled part done, or doing it yourself with someone checking it afterwards. 10. THE VERDICT - do it yourself / do it with help / get someone in, with reasoning. 11. IF DOING IT MYSELF - what to read or watch first, and the one thing not to get wrong.
What you get: A safety gate, regulatory and tenancy checks, what the job involves, realistic timing, what goes wrong and an honest cost comparison.
Tip: Point 7 is the decisive one. The question is not whether you could do it, but what happens if you get it wrong and whether you can undo that.
Diagnose a problem in your home
Work out what is causing a household problem.
Help me work out what is wrong. THE SYMPTOM: [WHAT YOU ARE SEEING, HEARING OR SMELLING - be specific] WHERE: [LOCATION IN THE PROPERTY] WHEN IT HAPPENS: [always / sometimes / after something specific / at certain times] HOW LONG IT HAS BEEN HAPPENING: [TIMEFRAME, AND WHETHER IT IS GETTING WORSE] WHAT CHANGED BEFORE IT STARTED: [ANYTHING - weather, work done, new appliance, season] THE PROPERTY: [AGE, TYPE, ANYTHING RELEVANT] WHAT I HAVE TRIED: [IF ANYTHING] Produce: 1. THE URGENCY CHECK first - whether this needs attention now, soon, or can wait. Some household symptoms indicate something that gets rapidly worse or unsafe: water near electrics, a gas smell, a sudden structural crack, or anything involving burning smells. If mine is one, say so immediately and what to do. 2. THE LIKELY CAUSES - ranked, each with: - The mechanism: how this cause produces this exact symptom - Whether it fits the timing and conditions I described. The 'when it happens' answer is usually the most diagnostic information available. - How to confirm or rule it out, as a specific check I can do 3. THE TIMING CLUE - what the pattern tells you. A problem that appears only in cold weather, only when it rains, only when the heating is on, or only when an appliance runs points strongly in specific directions. Interpret mine. 4. THE ELIMINATION - causes that would produce a similar symptom but are ruled out by what I described, and what rules each out. This narrows the investigation. 5. THE CHECKS IN ORDER - what to look at first, being the cheapest and most informative. Include what to look for and what each result means. 6. THE 'IT MIGHT NOT BE WHERE IT APPEARS' WARNING - particularly for water, smells and noise. Water travels along surfaces and appears far from its source; a damp patch is frequently not below the leak. Say where else to look. 7. WHAT NOT TO DO - the tempting responses that make diagnosis harder or damage worse: painting over damp, sealing something before finding the source, or removing evidence before anyone can see it. 8. WHEN TO GET A PROFESSIONAL - and which trade. Getting the wrong trade out is a common and expensive mistake; say which one this symptom points to. 9. WHAT TO TELL THEM - the specific information to have ready, which makes the visit faster and cheaper. 10. THE DOCUMENTATION - what to photograph and record now, particularly if this may involve insurance, a landlord, or a warranty claim. This is a reasoning aid, not an inspection. Anything involving gas, electrics, structure or safety needs a qualified person.
What you get: An urgency check, ranked causes with confirming tests, the timing pattern interpreted, what to check first and which trade to call.
Tip: Point 6 catches the most common household misdiagnosis. Water appearing in one place is regularly entering somewhere else entirely.
Plan a decorating or renovation job
Work out what a project involves before starting it.
Help me plan this home project. WHAT I WANT TO DO: [THE PROJECT] THE SPACE: [ROOM, SIZE, CURRENT STATE, PROPERTY AGE AND TYPE] MY EXPERIENCE: [WHAT YOU HAVE DONE BEFORE] BUDGET: [AMOUNT] TIME AVAILABLE: [WHEN AND HOW MUCH] WHO ELSE LIVES THERE: [AND WHETHER THE SPACE CAN BE OUT OF USE] WHAT I AM UNSURE ABOUT: [YOUR QUESTIONS] Produce: 1. THE ORDER OF WORK - the single most important thing to get right, because doing things in the wrong order means redoing them. Broadly: anything structural, then first-fix services, then plastering, then decorating from the top down, then flooring, then fittings. Adapt to my project and say why each step precedes the next. 2. THE PREPARATION PROPORTION - in decorating especially, preparation is most of the work and most of the result. Say what proportion of the time this project's preparation should take, because it is usually far more than people expect and skipping it is the main cause of disappointing results. 3. THE MATERIALS LIST - with quantities calculated from my stated space, and a note on the wastage allowance to add. Include the things people forget: fixings, filler, sandpaper grades, dust sheets, masking, and cleaning materials. 4. THE TOOLS - what is needed, what to buy, what to hire, and what can be improvised. Hiring is often cheaper than buying for a one-off. 5. THE BUDGET CHECK - against my stated amount, with the parts that commonly overrun flagged. Add a contingency; older properties in particular reveal problems once opened up. 6. THE TIME ESTIMATE - realistic for my experience level, and broken into sessions if I am doing it around other commitments. Include drying and curing times, which cannot be compressed and frequently dominate the schedule. 7. THE UNKNOWNS - what you will not know until you start: what is behind the wall, the state of the surface underneath, whether the previous work was done properly. For each, what it would mean if it is bad. 8. THE LIVING ARRANGEMENT - given who else lives there, how disruptive this is and for how long. Dust, no use of the room, and the state of the rest of the house. This is usually underestimated and is a common source of household friction. 9. THE POINT OF NO RETURN - the step after which you are committed and the room is unusable until finished. Know where it is before crossing it. 10. WHAT TO GET SOMEONE ELSE TO DO - the parts of this project that are worth paying for, given my experience. 11. THE FIRST STEP - and what to do before that: check, measure, or test.
What you get: The correct order of work with reasoning, the preparation proportion, a materials list including forgotten items, and the point of no return.
Tip: Point 2 is the one people ignore and then regret. In decorating, the preparation is the job, and the painting is what you do at the end.
Get and compare quotes from tradespeople
Hire someone without being overcharged or disappointed.
Help me get and compare quotes for this work. THE WORK: [WHAT NEEDS DOING] MY PROPERTY: [TYPE, AGE, ANYTHING RELEVANT] QUOTES I HAVE: [PASTE THEM, or 'none yet'] MY BUDGET EXPECTATION: [IF YOU HAVE ONE] TIMELINE: [WHEN YOU NEED IT DONE] WHAT I AM WORRIED ABOUT: [YOUR CONCERN] Produce: 1. WHAT TO ASK FOR - the specification to give every tradesperson, so the quotes are comparable. Quotes for different scopes cannot be compared, and vague requests produce vague quotes. Write the description of the work, including: exactly what is included, the standard expected, what materials, who supplies them, and what making good is included. 2. THE QUESTIONS TO ASK each one: - What is and is not included - Who does the work: them, or someone else - How long, and when they could start - What happens if they find a problem once they start - Payment terms: deposit, stages, and final payment - Whether the price is fixed or an estimate, and what would change it - Insurance and any relevant certification - Recent similar work you could see or references 3. WHAT A GOOD QUOTE CONTAINS - written, itemised, with the scope defined, materials specified, timescale, payment terms, and their details. A number in a text message is not a quote. 4. COMPARING MY QUOTES - if I pasted them: put them on the same basis. Identify where they cover different scopes, where one includes something another does not, and where the difference is materials rather than labour. The cheapest is frequently cheapest because it excludes something. 5. THE WARNING SIGNS - pressure to decide immediately, a large deposit up front, cash-only, no written quote, no fixed address, a price far below the others, and an offer to start tomorrow on work that should be booked weeks ahead. 6. WHY THE CHEAPEST IS OFTEN NOT - what is usually missing: preparation, making good, waste removal, or the quality of materials. Ask what each has assumed. 7. THE PAYMENT STRUCTURE - what is reasonable. Some deposit for materials can be normal for larger jobs; paying a large proportion up front is not. Never pay in full before completion. Say what is appropriate for a job of this size. 8. THE CHECKS TO MAKE - certification for regulated work, insurance, and whether the work needs any approval or notification. What to verify and how, noting this varies by country. 9. WHAT TO AGREE IN WRITING before work starts - scope, price, timescale, payment stages, and what happens if additional work is found. 10. THE HONEST PRICE QUESTION - if I gave a budget expectation, whether it is realistic for this work, so I am not searching for a quote that does not exist.
What you get: A specification that makes quotes comparable, the questions to ask, warning signs, payment structure guidance and what to agree in writing.
Tip: Point 1 is what makes comparison possible. Three quotes for three different interpretations of the job cannot be compared, and that is the usual situation.
Organise and declutter a space
Sort out a room or cupboard that has got out of hand.
Help me sort out this space. THE SPACE: [WHAT IT IS AND ROUGHLY HOW BAD] WHAT IS IN IT: [THE KINDS OF THINGS] WHY IT GETS LIKE THIS: [YOUR SENSE OF THE CAUSE] WHO ELSE USES IT: [PEOPLE] TIME AVAILABLE: [HOW LONG YOU CAN GIVE IT] WHAT I HAVE TRIED: [IF ANYTHING] WHAT MAKES IT HARD: [sentimental items / not knowing where things should go / other people's stuff / not enough storage] Produce: 1. THE CAUSE - spaces get cluttered for identifiable reasons, and organising without addressing the cause means it returns within months: - No designated home for things, so they land wherever - The home is inconvenient, so things do not get put back - More things than storage - It is the room where things go when there is nowhere else - Decisions being deferred, so undecided items accumulate From what I described, which applies. 2. THE SCOPE - given my available time, do one defined area properly rather than starting the whole room and running out of time, which leaves it worse. Say what to tackle. 3. THE METHOD - the order that works: take everything out of the defined area, sort it, clean the space, then put back only what belongs. Sorting in place does not work because the existing arrangement constrains the thinking. 4. THE SORTING CATEGORIES - keep here, keep elsewhere, deal with later (a defined box with a date), pass on, recycle, discard. Have the bags and boxes ready before starting. 5. THE DECISION RULES - for the items that stall the process: when did I last use this, would I buy it again, am I keeping it because of what it cost, and is it being kept in case rather than for a reason. Give the questions, not a rule that says throw things away. 6. THE SENTIMENTAL ITEMS - if I said these are the problem, handle them separately and last. They slow the whole process and require different thinking. Practical options: keep a defined amount, photograph things you want to remember but not store, and keep the best example rather than all of them. 7. OTHER PEOPLE'S THINGS - do not discard them, and do not decide for other people. What to do instead: gather them, give them back, and set a date. 8. THE PUTTING BACK - things used often go where they are easy to reach; things used rarely can be awkward. Most storage problems are actually accessibility problems. 9. THE ONE-IN-ONE-OUT DECISION - whether this space needs a rule to stay sorted. 10. THE MAINTENANCE - the small regular thing that keeps it this way, proportionate to how much I will actually do. 11. THE REALISTIC NOTE - if the volume exceeds the storage, no organising fixes it. Say so if that is the situation.
What you get: The cause diagnosed, a scoped area, an empty-sort-clean-replace method, decision questions, sentimental items handled separately and a maintenance habit.
Tip: Point 1 is why decluttering keeps needing redoing. If things have no convenient home, they will be back on the floor by spring regardless of how well you sorted them.
Work out a maintenance schedule for your home
Look after a property before things go wrong.
Help me set up home maintenance. THE PROPERTY: [TYPE, AGE, ROUGHLY WHERE - climate matters] WHAT IT HAS: [heating system, garden, roof type, appliances, anything notable] HOW LONG I HAVE BEEN HERE: [TIME] WHAT I ALREADY DO: [CURRENT MAINTENANCE, if any] MY ABILITY AND TIME: [WHAT YOU CAN AND WILL DO] WHAT HAS GONE WRONG BEFORE: [IF ANYTHING] Produce: 1. THE PRINCIPLE - maintenance is cheap and repair is not. The jobs below are all substantially cheaper than the damage they prevent, which is the only argument for doing them. 2. THE SAFETY ITEMS - first and non-negotiable: smoke and carbon monoxide alarms tested and batteries replaced, any gas appliance serviced by a qualified person on schedule, and electrical safety checks as applicable. State the frequencies and that local requirements vary. 3. THE SEASONAL SCHEDULE - for my property and climate: - Autumn: the things to do before winter, particularly around water, heating and drainage - Winter: what to watch for - Spring: what to inspect after winter damage - Summer: the jobs that need dry weather Each with why it matters and what it prevents. 4. THE ANNUAL LIST - the once-a-year items, with the best month for each. 5. THE OCCASIONAL LIST - things on a multi-year cycle, with rough intervals. 6. THE HIGH-CONSEQUENCE ITEMS - the small number where neglect causes serious, expensive damage. Usually anything involving water getting in, drainage, or the roof. These are the ones to prioritise if nothing else gets done. 7. THE EARLY WARNING CHECKS - what to look at regularly and what you are looking for. Catching something early is the difference between a small job and a large one. 8. WHAT NEEDS A PROFESSIONAL - and roughly how often, so it can be budgeted rather than arriving as a surprise. 9. THE REALISTIC VERSION - given what I said I will actually do, the short list that matters most. A comprehensive schedule that gets ignored is worth less than five things that get done. 10. THE RECORD - what to write down: when things were serviced, what was done, and by whom. Useful for warranties, for selling, and for knowing when something is due. 11. THE PREVIOUS PROBLEMS - I said what has gone wrong before. Whether there is a maintenance item that would have prevented it, and whether it is likely to recur.
What you get: Safety items first, a seasonal and annual schedule with reasons, the high-consequence items prioritised and a realistic short version.
Tip: Point 6 is where the money is. Most expensive house problems start with water getting in somewhere small and going unnoticed for a year.
Improve a room without major work
Make a space better with limited money and effort.
Help me improve this room. THE ROOM: [WHAT IT IS, SIZE, WHAT IT IS USED FOR] WHAT IS WRONG WITH IT: [YOUR SENSE OF THE PROBLEM - be specific if you can, vague is fine] WHAT IS IN IT NOW: [FURNITURE, COLOURS, FLOORING, LIGHTING] NATURAL LIGHT: [HOW MUCH, AND WHICH DIRECTION IF YOU KNOW] BUDGET: [AMOUNT] WHAT I CANNOT CHANGE: [rented, structural, furniture you must keep] WHO USES IT AND HOW: [THE ACTUAL USE] Produce: 1. THE DIAGNOSIS - I described a vague dissatisfaction. Translate it into specific causes. Rooms feel wrong for identifiable reasons: - LIGHTING: one harsh overhead light is the most common single cause of a room feeling unpleasant, and the cheapest to fix - LAYOUT: furniture arranged around the walls, or blocking the natural path through the room - SCALE: furniture too large or too small for the space - CLUTTER: visual noise rather than the room itself - NO FOCAL POINT: nowhere for the eye to rest - MISMATCH: the room is arranged for a use other than its actual one Say which apply to mine. 2. THE LIGHTING FIX - almost always the highest-return change. Several lower light sources at different heights instead of one ceiling light, warmer bulbs, and lamps where people actually sit. Specify what to add and where, within my budget. 3. THE LAYOUT - a rearrangement of what I already have. This costs nothing and is frequently the biggest improvement. Say what to move and why, considering how people walk through the room and what they look at. 4. THE USE CHECK - I said what the room is actually used for. Rooms are often arranged for an imagined use rather than the real one. Say where mine does not serve what actually happens in it. 5. THE FREE CHANGES - things that cost nothing: moving furniture, removing something, changing what is on the walls, clearing surfaces, and changing what you see when you walk in. 6. THE BUDGET SPEND - given my amount, the specific things worth buying, in priority order. Lighting, textiles and one larger item usually beat many small purchases. 7. THE ONE BIG THING - if the whole budget went on one change, what would most improve the room. 8. WHAT NOT TO SPEND ON - the things that seem like they would help and do not, particularly small decorative purchases that add clutter. 9. THE RENTING CONSTRAINTS - if I said I rent, what is reversible and what needs permission. Plenty is possible without touching the walls. 10. THE ORDER - what to do first, so each step is worth doing on its own rather than the room being half-finished for months.
What you get: Your vague dissatisfaction translated into specific causes, a lighting fix, a free rearrangement, priority spending and a do-not-buy list.
Tip: Point 2 is the cheapest transformation available. A single overhead light makes almost any room feel worse, and two lamps fix it for very little.
Where AI actually helps here
- Narrowing down what is wrong from a description of the symptom
- Tool and material lists, and the order of operations for a job
- Explaining what a tradesperson’s quote actually covers
Where it falls down
- Gas, electrical and structural work, which is regulated for good reasons
- Local building regulations, which vary by country, region and often by property
- Knowing your house. Age, construction and previous work change every answer
The mistake almost everyone makes: Asking it whether you can do it yourself
It will tell you how. Ask instead: what could go wrong here, what is regulated, and at what point does this need a certified professional in [YOUR COUNTRY]? Gas and electrical work is legally restricted in most places, and ‘I watched a video’ is not a defence to an insurer.

Questions people ask
Can AI diagnose a household problem?
It narrows the possibilities from a good description, which saves time before you call someone. It cannot see, hear or smell the thing, which is where most diagnosis actually happens.
What DIY should I never use AI for?
Anything involving gas, mains electricity, structural elements, or asbestos. These are regulated in most jurisdictions and a confident wrong answer has consequences insurance will not cover.
