I have some experience with this. My elderly Mother has one of those custom designed kitchens you see in magazines. She spent big $ on it. A few years after the kitchen was completed a water supply line to the kitchen sink developed a leak. It was a corrosion leak. Anyway, like you, it was a complete mess. hardwood floor was ruined. it buckled. subfloor was ruined. Downstairs was an unfinished basement so only had to clean up the wet floor. Cabinets had to come out. Granite tops had to be replaced. it was a nightmare.

Became more of a nightmare after contacting the insurance company. Insurance company recommended ServPro and some other outfit. Basically got the same thing as you did. I wasn't comfortable with them being in the house with nobody around. Didn't hire either one of them.

I contacted a contractor who did my master bath over and asked him to look over my Mother's kitchen which he did. Made several recommendations for local guys in my Mom's area. Long story short, the job got done to her complete satisfaction with finding the exact same granite color that she had before. She was concerned the granite color wouldn't match the cabinet finish.

So, might be best to be your own contractor and get some independents to do the work. I did a portion of the demolition work and disassembly and removal of the cabinets. It wasn't really that hard to do. Doing the rebuild and finish work I left to the pros. It looked like nothing happened when it was complete.

I wish you the best in this. it is very unnerving and huge disruption.
