I've always wanted a JWorlds.net Iguana Cage, and when I saw a great deal on a used cage (6L x 7H x 3W), I had to have it. I measured the spot I wanted it to go in, purchased it from the seller, and all that remained was to get it from her Long Island garage into my 4th floor Manhattan walkup. Bill Ingerman and his crew accepted the job, which I thought would take about a half hour at most - the seller told me the cage broke down into 3 "easily moveable" pieces, each one 3' wide x 6' long x 3' tall, and not very heavy.
That was inaccurate.
The base of the unit was fully waterproofed with 1" thick silicone and caulking. It was HEAVY. It also didn't fit up my narrow staircase, which I hadn't thought to measure (my stupidity). None of the other pieces fit, either. (The seller also hadn't drained the water portion of the cage, so I had a minor flood on my stairs at exactly the moment that my landlord peeked into the hallway to see what the racket was) I felt awful.
Bill approached the situation with humor and creativity. He & his crew broke down the other two pieces using a power drill and took them upstairs. Then, after 3 hours, when it became apparent that the base was just not going to fit, he offered to take it back to his workplace and dismantle it there, with a saw if necessary. I had no alternative, and felt like a terrible inconvenience.
The next day Bill came back with the bottom in pieces - he'd had to cut it apart with a saw. I had absolutely no idea what to do and was having visions of having to find a carpenter to put it back together for me, but he and his crew stayed and reassembled the entire thing.
I now have an amazing cage and a very happy iguana...and I know who I'll use (and refer!) any time I have to move anything again.
