looking at prices on floor sanders........holy shit.

 

if i were gonna try to lower the high spot some by sanding....wonder how i'd make out with a handheld sander?

If you went with a hand sander or belt sander you'd probably get it level by Christmas...

 

I hope you're not considering buying a floor sander, you can rent them from just about anywhere. Although at an inch and a half high throughout the whole floor, that's a whole lot of sanding. Still think your best bet is to build up to match, or as someone said earlier, consider ripping everything out and laying down fresh plywood before putting new underlayment and laminate on top.

Be careful how much floor you remove, it's standing on the first floor or laying in the basement

theres a degree of practical application for all matl's and tools. if your actually beyond an inch out of whack I'd be thinking wood replacement. and dont forget all the nails, staples even petrified knots can give sandpaper or sharp blades an early death. perhaps laying down new plywood every where except the hi area and then floating some filler to level off that area to the new ply is the option.

I agree.   The issue I see with "filling to the high spot" is that at some point, the flooring runs to another floor section and they're probably not going to match. You'll either have a permanent toe stub or need to sand the crap out of the last 4 feet or so to get them to mate level.

 

It sounds like a pain, but pulling out the old tongue and groove and installing new plywood really is the right answer.  I re-floored most of my house recently and struggled with the old tongue and groove.  Once I decided to cut out all the problem sections, it was like a voice from above said "And the TRUTH shall set you free!".    After that it was really just a basic carpentry job of getting it level rather than sanding here, shimming there, on and on.   I even replaced two floor joists that were under the old bathroom and needed to go.  That would have almost impossible while the tongue and groove was down.  Once it was out, the light bulb came on and two new joists went in.   The best part was the the old house and new addition now perfectly match and are solid as a rock.

ok i lifted the end of one of the boards that's on the high spot. the high spot is right on the main beam running front to rear in the house. i believe that even if i were to pull this up, and replace it, i'd still have that high spot. i bought a small laser level, to make it easier to measure the difference in heights. i was way off on my "guestimation". it's only about a half inch.

 i'm guessing my best bet's gonna be to use something to build it up. was thinking of doing the plywood idea one of you guys mentioned. it doesn't hafta be pretty. it just has to be level and secure for the laminate.

 

 again, thanks for all of the advice guys, any and all is welcome and appreciated!

How did it turn out?
