An emergency guide that tells you what to do in the first hour of a leak and matches you with available local pros.
The problem people are complaining about
On 2026-10-21, a thread titled “Ceiling leaking help” reached #72 in our daily ranking of home & diy problems on Reddit. In home & diy, people most often struggle with repairs, renovations, doors, walls, plumbing and choosing between DIY and hiring a pro; this one stands out because the person asking has a concrete, repeatable need rather than a one-off emergency. When the same question keeps appearing in public, it usually means existing products either don't reach these people or don't answer the question in the way they need. That gap is what Leak Triage aims at.
Who the customer is
Homeowners and renters with water coming through the ceiling who need to know what to do right now and who to call.
In short, the first customer to target is: Homeowners and renters facing water leaks. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.
The idea
Leak Triage is a lead-gen marketplace idea. An emergency guide that tells you what to do in the first hour of a leak and matches you with available local pros. It makes money through lead fees from plumbers/roofers.
| Business model | Lead-gen marketplace |
|---|---|
| How it makes money | Lead fees from plumbers/roofers |
| Difficulty | Med |
| Opportunity score | 7/10 — Urgent, high-value leads; marketplaces exist but triage content is weak. |
Pricing guess
Estimate: $30-100 per lead from plumbers and roofers. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.
MVP you can build
Weekend: triage decision tree + form that emails local pros (one city). Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.
How to validate it in three steps
- Publish the first-hour triage guide and measure traffic.
- Add a lead form in one city and count requests.
- Recruit three local pros to pay for leads.
Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.
Competition & existing alternatives
Angi, Thumbtack, HomeAdvisor Before building, try each alternative as a customer would and note exactly where it fails the people in the threads; that gap is your positioning.
Risks
- Big marketplaces dominate local leads.
- Lead quality disputes with pros.
- Needs city-by-city supply.
How we scored it
Opportunity score (7/10) is an editorial judgement combining four factors: how strong and frequent the demand looks, whether the customer already spends money on the problem, how crowded the alternatives are, and how much effort the first version takes. Signal score (2/10) is calculated from our data only: 2 points for one thread, 4 for two, 6 for three or more; +1 for each extra day the problem appears (max +2); and +2 if it ranked in the daily top 10, +1 for top 25, +0.5 for top 50. Neither score is a forecast. See how it works.
