Solid Hardwood, Engineered and Laminate Flooring - Level Sub-Floor vs. High Spots

HI,

I have been reading several threads regarding laminate flooring. My contractor is putting down Traffic Master laminate next week. In several of your posts I read that individuals are making sure there are no "high spots" or "low spots" in their sub-floor. I don't believe I have any of these but my floor does slope from one side to the other. The opposing corner of the bathroom is about 1 inch lower. This low area is where the toilet will be. My contractor indicates that as long as the slope has no high or low spots everything will be fine. He has not installed this floor before so his experience is low. Please let me know if he is correct and if not please outline the consequences of installing as is so I can sound somewhat intelligent.

Also, the edges of the laminent will be covered by the base board but what about the gap around the tub. Should this be filled with the clear silicone caulk or would there be a better solution?

Thanks for any help. I have gleaned valuable information from your forum. I actually sound quite intelligent when speaking about home improvement projects with friends ( and my contractor).

I'm going to pass on the sloping floor question because I am evil.

As for the bathtub situation, try to find a transition molding piece for that purpose, if the manufacturer has one. I know that Pergo sells a "Carpet Transition Strip/End Molding" piece that consists of a 1-3/4" (or thereabouts) "T"-style molding laid atop a butt (end) piece. The butt is placed flush with the bathtub and the T-piece bridges the gap between the floor and the butt. That should be more professional looking. Apply any sealant, etc. as per manufacturer instructions for installing around bathtubs, water sources, etc.

Flat is what your looking for.

1/8 of an inch in 6 feet is the spec for subfloor flatness with a floating laminate installation. An 1/8 of an inch!!!

If it makes a dramatic slope, it will have to be prepped, to bring the subfloor to flatness specs.

Floor prep is the most overlooked aspect of any flooring installation, yet it is the most important, and usually takes longer and is harder on the body then actually installing the floor!!!!

Ya, I can spot an internet savy client, as the interview progresses. I love them!
They know what it takes to do the job right, and understand the extra cost involved in doing it right, and slapping it on the floor.
