Wife and I stopped off at LL to get a quote on a 15x15 bedroom to put in a cork floor. We hung around for about an hr or longer waiting on the guy to come up with it. It was to be cork over our wooden floor. Finally he shows up with the quote in hand and I take my calculator and come up with a per sq ft price, I can't believe my eyes, so after doing it a couple of times and getting same answer I ask for a per sq ft cost. He beats around the bush tries to say will its not the same yadah yadah. HUH? Take you price and divide it by the sq ft in the room and tell me what it is. He finally does it and writes it down. I look and yes its the same thing I came up with.
I multiply it by the number of sq ft in my home: 2366. Cost to do the whole house? Little over $32,000 bucks. I tell that to the guy and he has deer in the headlights look. Then says well we can find some discounts if you want to do the whole house. IIRC the cork was $1.86 per sq ft, so I asked the guy how he came up with the price. After much leaning on him I got some but not all answers: Glue, rags, gloves, knives, travel cost, it went on and on.
What they do is they make it sound cheap, like right now they have Lisbon cork on sale for $1.29 per sq ft so the initial quote you get is $1.29 x # of sq feet...so a 10x10 room would be #129.00. This is called the "hook", now to reel you in. This is were they get you as the math becomes real fuzzy past that point as it all labor and materials and they pad this beyond your wildest imagination. IIRC the guy quoted 25 gals of glue for my 15x15 room. When I questioned it, then it was it had to be put on thick and it only comes in 5 gal buckets and it went on and on from there...
Avoid them at all costs.
