You can feel the cold. You can see the bill. You can't see where the heat goes.
One room never warms up, no matter what the thermostat says.
Window, door, outlet, attic? Guessing gets expensive fast.
The door stopper went on the wrong door. The real leak was somewhere else.
And if you rent, you can't renovate anyway.
The fixes are cheap. Most cost under $15. The hard part is knowing which leaks you actually have, and which ones to fix first. That's what this guide solves.
Most homes leak heat through the same 8 places.
The guide takes you to each one, in order, with a page of what to check and how to fix it.

Practical help for homes that never feel warm enough.
DraftHunt is a small, independent business that makes simple guides for keeping your home comfortable without expensive renovations. We started with one question: why do so many homes stay cold even with the heat turned up? Most of the time the answer is air leaks, and finding them shouldn't take a contractor.
Every guide is written in plain English, sticks to cheap fixes you can do yourself, and is honest about when to call a professional. If it doesn't help you, you get your money back. Questions go to a real person at support@drafthunt.com.
Before you buy
Do I need any tools or experience?
No. The tests use a tissue, an incense stick, a flashlight and a sheet of paper. Most fixes peel and stick, slide on, or press in by hand.
I rent. Will this work for me?
Yes. Fixes marked "Renter-friendly" are removable and usually need no landlord approval. For problems that are your landlord's job, the guide includes a ready-to-send repair request letter.
Will this lower my heating bill?
Sealing drafts keeps warm air inside, so many homes feel warmer and need less heating. Every home is different, so we don't promise a specific saving. If the guide doesn't help you find and fix drafts, you get your money back.
What format is it? Is anything shipped?
Nothing is shipped. You get PDF files by email right after checkout. They work on any phone, tablet or computer, and the worksheets are made to print.
How long does it take?
About 30 minutes to find and score your leaks, and one weekend to fix the important ones.
How much will the fixes cost?
Most single fixes cost $5 to $15. The guide's starter plan for a typical home is about $50 in parts. You only buy fixes for leaks you actually find.
My home is fairly new. Is it worth it?
Newer homes leak less, but door seals wear out, and outlets, attic hatches and garage doors are common weak spots. The 30-minute hunt will show you quickly.
What if it doesn't work for me?
Email us within 30 days of purchase and we'll refund you in full. See our refund policy.
