How it works

From "what's leaking?" to fixed — one calm step at a time.

Here's the whole journey through a repair with Chamfer, from the moment something drips to the moment you put your tools away.

1Show us the problem

Start with a photo, a sentence, or a browse.

Point your camera at the drippy valve or the mystery switch and Chamfer identifies it. Prefer typing? "My toilet won't stop running" works just as well. You can also browse the guide library by room or category.

Compression shutoff valve

That drip at the stem usually means a worn packing washer.

2Size it up

Know exactly what you're signing up for.

Before you commit, every guide shows the difficulty, the time it really takes, and the tools and parts you'll need — so there are no surprise hardware-store runs at step 5. If the job's beyond DIY, it says so here, up front.

Unhook the old flapper

Unclip the chain from the flush lever arm, then slide the flapper's ears off the pegs on the overflow tube.

⚠ Before you continue

Water should already be off at the supply valve. If the tank refills on its own, stop and re-check step 2.

Done — next step
4Ask anything

Stuck? Ask — it knows the step you're on.

"Which way do I turn this?" "Mine looks different." The AI helper sees which guide and step you're on, so answers fit your actual situation — not a generic forum thread from 2014.

Ask Chamfer
The shutoff valve won't turn — should I force it?
Don't force it — older valves can snap and flood the room. Try gently working it back and forth a few degrees at a time. If it's stuck solid, use your home's main shutoff instead. Want me to show you where that usually is?
Yes please
Usually it's where the water line enters the house — check the basement wall facing the street, or near the water heater…

5The safety net

Risky steps get a full stop — not fine print.

Anything involving gas, mains electricity, or structure gets an intercept: Chamfer stops, explains the risk in plain English, and makes you confirm before continuing. And when a job genuinely calls for a licensed pro, it says exactly that.

⚠ Stop — safety check

This step involves live wiring.

Switch off the breaker for this room, then test the fixture wires with a non-contact voltage tester. No tester? Don't guess — get one, or get a pro.

6Finish strong

Done. See what you saved — and what's next.

Every finished repair shows what a service call would have cost. Chamfer keeps a record of what you've fixed and quietly reminds you about the seasonal upkeep that prevents the expensive stuff.

Who does what

The help is AI. The guides are human.

More than repairs

Between fixes, Chamfer keeps your home on schedule.

The repair guides are the rescue. These are the habits that mean you need rescuing less often.

A maintenance calendar built for your home

A quick setup quiz tells Chamfer what you've got — furnace, gutters, water heater — and builds a seasonal reminder schedule around it. Subscribe once and it lives in your phone's calendar.

A home health score

One number that tells you how your home is doing, weighted so safety counts double. Check things off and watch it climb — plus a logbook of everything you've done.

Your fixes, remembered

Every guide you save, every repair you finish, and a running total of what you've saved doing it yourself. Put the phone down mid-job and pick up where you left off.
