10 Common Home Repairs You Can Diagnose With Your iPhone
Your iPhone is already your camera, calculator, and communication hub. With AI-powered apps like SnapFix, it can also become your home repair diagnostic tool — identifying problems, explaining causes, and providing fix instructions from a simple photo.
Here are ten of the most common household repairs that you can diagnose and often fix yourself using just your iPhone and basic tools. For each one, we explain what to look for, why it happens, and how AI photo diagnosis speeds up the repair process.

SnapFix: AI Home Repair Help
SnapFix uses AI to diagnose home repair problems from a photo. Snap a picture of any household issue — dripping taps, wall cracks, appliance problems — and get instant step-by-step repair instructions with shopping lists and cost estimates.
Plumbing repairs: dripping taps and running toilets
Dripping faucets and running toilets are the two most common plumbing problems in any home. A dripping faucet typically indicates a worn washer, O-ring, or cartridge. A running toilet usually means the flapper valve is not seating properly or the fill valve needs adjustment.
AI diagnosis helps by identifying the specific faucet type (compression, ball, cartridge, or ceramic disc) from a photo, which determines the exact repair approach. For toilets, a photo of the internal tank mechanism can reveal whether you need a flapper replacement, a fill valve adjustment, or a more involved repair.
Both repairs are well within DIY capability and typically cost under $20 in parts. The key is accurate diagnosis — using the wrong approach wastes time and money.
Wall and ceiling repairs
Cracks in walls and ceilings are extremely common and usually cosmetic rather than structural. Hairline cracks along joints are typically caused by seasonal expansion and contraction. Cracks radiating from door and window corners are usually from building settlement.
AI photo diagnosis can distinguish between cosmetic cracks (safe to patch) and potentially structural cracks (which need professional assessment). Warning signs that require a professional include cracks wider than 3mm, cracks that run diagonally across walls, or cracks accompanied by doors and windows that no longer close properly.
For cosmetic repairs, the fix involves cleaning the crack, applying flexible filler, sanding smooth, and repainting. Most wall and ceiling crack repairs take under an hour and cost less than $15 in materials.
Appliance and fixture troubleshooting
Flickering lights, squeaky doors, loose handles, and minor appliance issues round out the most common home repair requests. Many of these have surprisingly simple fixes that do not require a tradesperson.
Flickering lights are usually caused by loose bulbs, faulty switches, or incompatible dimmer switches — not wiring problems. Squeaky doors need a drop of lubricant on the hinge pins. Loose door handles typically just need tightening of the set screw. Washing machines that vibrate excessively may simply need their feet levelled.
AI photo diagnosis is particularly useful for appliance error codes and unusual symptoms. Snap a photo of an error display or unusual appliance behaviour and get instant identification of the issue and recommended fix.
Outdoor and weatherproofing repairs
Caulking around windows and doors degrades over time, allowing drafts and moisture intrusion. Peeling exterior paint exposes surfaces to weather damage. Blocked gutters cause water to overflow and potentially damage foundations.
These outdoor repairs are some of the most cost-effective DIY projects because they prevent expensive damage down the line. Re-caulking a window costs $10 in materials but prevents water damage that could cost thousands to repair.
AI diagnosis helps identify the severity of weatherproofing issues. A photo of cracked caulking tells you whether a simple re-caulk will suffice or whether the underlying frame needs attention first.
Building your home repair confidence
The biggest barrier to DIY home repair is not skill — it is confidence. Most common household repairs require only basic tools, inexpensive materials, and clear instructions. The role of AI diagnosis is to remove the uncertainty that makes people reach for the phone to call a tradesperson.
Start with low-stakes repairs like patching nail holes, tightening loose handles, and replacing tap washers. As your confidence builds, move to medium-complexity projects like toilet repairs and caulking replacement. Within a few months, you will have the skills and confidence to handle 80% of common household issues yourself.
Keep a basic tool kit ready: adjustable wrench, screwdriver set, pliers, putty knife, utility knife, tape measure, and a torch. With these tools and an AI repair app on your phone, you are equipped to diagnose and fix most common home problems.
Frequently asked questions
Can my iPhone really diagnose home repair problems?
With AI-powered apps like SnapFix, your iPhone camera can identify common household problems from photos. The AI analyses the image, diagnoses the issue, and provides personalised repair instructions with materials lists.
What are the most common home repairs to learn first?
Start with dripping taps, nail hole patching, loose handles, and caulking replacement. These are the most frequent household issues, the cheapest to fix, and the easiest to learn. Each one builds skills for more complex repairs.
When should I call a professional instead of DIY?
Call a professional for electrical work beyond basic switch replacement, gas-related issues, structural cracks, roof repairs, and any plumbing that involves main water lines. Safety should always come before savings.
