Sorry about the loss, I went through that in 84. Also lost 99% of my tools in that fire.
BUT I want to tell you to not make assumptions based on peoples opinions here.
Tools in tool boxes do not usually lose their temper. Just doesn't get that hot. When it does get that hot the boxes burn.
You can itemize all the tools, takes hours, and then submit them as individual tools on the insurance. Since you probably bought sets you can see how much more the itemized tools can add up to...
Most insurance only pays a percentage on tools.
Check and see if the policy has a limit, you may be over it, in which case the adjuster will usually just take a picture you submit and pay you the max.
Even if they only give you say 25-50% (normal) amount for the tools, if you get a catalog from Sears, etc. and itemize them individually, you may easily recover more than your investment.
DON'T throw the tools away.
As I said, most tools will survive a fire in a tool box with only cosmetic damage. This you can clean off.
So 1. Determine what they will pay.
2. Itemize and document the value of each tool.
3. Submit the total.
4.Get the money.
5. THEN and ONLY then, clean up the tools.
6. Toss anything that's questionable. You will be surprised at how many tools survive.
7. Keep a LOT of spare tools, and buy the replacements in sets and save big bucks.
8. Ignore all the tales about weakened tools. Some will be. But you will know it when you look at them. Most of the ‘damage’ to the tools will be from water used to put out the fire. You may be taking ratchets apart and cleaning out the dried grease, but sockets, wrenches, extensions, breaker bars, etc. will be fine.
I believed everyone’s stories about the heat damaging my tools. I couldn’t bear to toss thousands of dollars worth of tools after the fire. The boxes were melted, the tools were in piles. So I stored them in old ammo boxes for 5 years, then gave most of them to a friend. Who cleaned them up and is still using them professionally today. NONE failed. NONE.
I cleaned up the rest after leaving them in the ammo boxes for 25 years. And am using them today. No failures.
