Same house, two ways
The usual way
Tom's way
The furnace dies on the first cold night
A twenty-minute check on a mild afternoon in October
A $5 washer hose floods the laundry room
Braided hoses fitted on a Saturday morning
The repairman says "you could fix it, but..."
You know the half-the-price rule before he arrives
The bill goes up and nobody knows why
You read the bill and find the leak

Why I wrote it down
For 31 years on a small-town fire department in rural Ohio, I walked into other people's houses on the worst day they ever had. A fire in the laundry room. A basement full of water at two in the morning.
What I remember most is how often the house had been warning them. The dryer took two cycles to dry towels. The toilet hissed all spring. The filter had been gray since March.
So I wrote down the check I do in my own 1910 farmhouse every month, and the repairs I would show you if I came over on a Saturday with a toolbox.
Every step is marked You or Pro, so you always know when to put the screwdriver down and call somebody.

No guesses
Before you buy
Yes. Most of the book is looking, listening and small habits. Every step is marked You (anyone can do it) or Pro (book someone), and the repairs say exactly when to stop.
For the monthly checks, a flashlight and a pencil. For the repairs, a basic toolbox (about $40 to $70) covers every You job; the parts list tells you what to buy.
Yes. The checks, the bills and the leak tests work in any home, and the "Make it fit your house" page explains what to report to your landlord.
No. It is for anyone with a house to look after. It is in large print so it is easy to read in a basement with a flashlight.
No, it is an e-book: a large-print PDF. Read it on a tablet or print it and keep it in a binder by the furnace.
No. You pay once. There is no account and no subscription.
No brands, no affiliate links. Most of the savings in the book cost nothing.
It is general home-care education from public sources. Gas, electrical panel, roof and structural work are for licensed professionals, and the book says so.
