Who gave them permission to approach your home?
After any storm, dozens of unverified contractors descend on neighborhoods before insurance adjusters even arrive. No license check. No insurance verification. Just a truck, a pitch, and pressure to sign today.
No Soliciting signs carry zero legal weight. City registries only work if the solicitor checks them — they don’t. Ordinances require police enforcement that never comes. None of it was designed to stop a determined storm chaser.
No documentation of who came to your door, when, what they said, or what they did to your home. No accountability. No paper trail. Until now.
A weatherproof sign with a cryptographically unique QR code engraved to your address. Not a generic sticker. Not a printout. Unique to your property. Every sign is tied to one address in the KnockBlock database — permanently.
Every scan routes through the KnockBlock system instantly. Unverified visitors receive a boundary message and a recording notice. Verified contractors receive controlled, preference-based access. Every single scan is logged permanently — device type, approximate location, timestamp. That log is yours.
The KnockBlock verified contractor network requires: active business license, current insurance certificate, individual background checks on every doorknocker, signed code of conduct, mandatory probationary period before full access, random compliance audits, and a strike system with public violation records. Suspension of a company cascades immediately to every rep under that company. No exceptions.
The homeowners who put up KnockBlock signs aren’t your enemy — they’re your best customers. They care about their homes. They do their research. They want to know who they’re letting in. KnockBlock gives legitimate contractors a way to prove they belong at the door before they knock.
Stand out in a market flooded with chasers. Your KnockBlock verification is visible to every registered homeowner in your territory.
Registered homeowners have opted in to verified contractor contact. You’re not cold knocking — you’re a welcome visitor.
Scan analytics, territory mapping, and storm alert data available on the Pro tier. Know where to be before the storm clears.
When someone scans the QR code on a KnockBlock sign, three things happen instantly — the address is resolved, the scanner’s verification status is checked, and the interaction is permanently logged. That record belongs to the homeowner.
KnockBlock is building the most complete verified record of residential properties that has ever existed. Every contractor visit logged. Every repair documented. Every system age tracked. Founding members start building that record on day one. Add past work, upload old permits, document what you already know — and from here forward, everything new gets captured and verified automatically.
When a new homeowner registers your address, they receive your home’s full verified history — every contractor who touched it, every system documented, every warranty on file. Your KnockBlock record becomes one of the most valuable documents your home has ever had.
Elderly homeowners are the most targeted demographic for contractor fraud. They’re home during the day. They grew up trusting people who come to the door. And they’re preyed upon relentlessly — by storm chasers, fake inspectors, and high-pressure salespeople who know exactly what they’re doing.
The 30 Program is simple: for every 10 paid homeowner signups, KnockBlock provides one fully covered KnockBlock membership to a qualifying elderly or disabled homeowner at no cost. Rolling. Permanent. No expiration.
500 homeowner spots and 50 contractor spots per market. Founding members lock in pricing for life, their signs ship before public launch, and they get direct input on platform features as we build.
Founding spots are capped at 500 homeowners and 50 contractors per market across 10 markets. When they’re gone, they’re gone.
