Questions about replacing timber floor
Well after much consideration, the better half and I decided to hang the expense and replace the damaged floor in our kitchen, dining room and two hallways. Have a read of this thread for background information and pics.
We've decided that we both like the look of "Australiana" grade 80mm Australian Beech secret nailed. Before we go ahead with the floor I have a few questions that I need to ask from informed, impartial persons in the know.
Firstly; The flooring mob said the preferred method is to totally remove the old boards so they could lay the new boards on the current joists. They did say they can install ontop of existing floors, though this was not the recommended method. A carpenter I spoke with said he would just lay the new boards straight over the current boards.
Secondly; There are several "higher" spots that are noticable to the eye in the current floor. When I pointed these out to the carpenter he said these high spots can just be planed so the floor is level again, prior to the new floor being layed on top. The height difference would be approx 2-3mm over 400-500mm I guesstimate. Does this sound right way to go about it?
Thirdly; The flooring mob recommended that the boards be laid 90 degrees to the existing boards (if we decide to go straight over the old floor) so as not to follow any imperfections in the floor. The carpenter didn't seem to think it was an issue which way we laid the floor. How important is this factor?
Lastly; We have been quoted $43.00 sq metre for supply only of the "Australiana" grade Aussie Beech in 80mm width OR $105.00 sq metre supply, installed, sanded and polished. Do these prices sound reasonable? Am I being ripped off? Also, should I end up getting my carpenter to install the floor, what is a reasonable rate just for sanding and polishing?
