Just had a new floor put down.I'm happy with the whole job except in the middle of my kitchen there was a wavy spot.It looked to me as though the floor didn't seat properly, maybe the subfloor played a roll in it.One board dips for a few feet.I told the contractor and he made an attempt to sand it down.It fixed it somewhat but I still don't think it's acceptable for a new install.The job took longer than expected and he was rushing at the end of the day.His apprentice did that area.When I told him originally he said he would do his best to sand it down.I asked him how he corrects something like that on a prefinished floor and he joked about it being the result of an uneven subfloor.
In my opinion to blame it on the subfloor is a copout.His apprentice should have spotted it when it was happening.He couldn't have tacked it down without spotting it.if there was a problem he should have brought it to my attention and we could have fixed it but he was rushing.
The other thing that played a roll I think is this.He ran the floor in the same direction as the plank subfloor instead of perpendicular to it.If that board lands on a planks edge I would imagine it would or could dip for the length of the board.I no carpenter but thats ;like a seam on a seam.what do you guys think.Help!!!

It is a result of an uneven subfloor.

The installer is not reponsible for rebuilding your subfloor, unless it is in the contract.

However, he is the professional, and he approved the subfloor that wasn't within specs.

He should have stopped when he found the problem, and offered you solutions and options, which of coarse would have meant more money involved in the installation, meaning more profit in his pocket.

Now he has installed this floor, without your signature saying you have been brought aware of the out of spec subfloors, and you chose to ignore those specs and to go ahead and install it, by your signature on the release waiver.


Have you paid him yet? If so, GOOD LUCK!!!

I would make them do it right. A judge will.

I'd like to hear more about this one. That in itself is a big no-no. The NWFA calls it "never marry a naildown floor"

LAYING A NEW STRIP FLOOR OVER AN OLD FLOOR
The existing wood floor can serve as a subfloor. Drive down any raised nails, re-nail loose boards and replace any warped boards that can't be made level. Sweep and clean the floor well, but don't use water.

Remove thresholds to allow the new flooring to run flush through doorways, remove doors and baseboards. Lay asphalt felt or building paper over the old floor.

Do not install the new floor to the old floor in the same direction. Install at a right angle or on a diagonal. If the preferred direction is in the same direction as the old floor, overlay the old floor with 3/8" to 1/2" plywood.
