Uneven kitchen floor (here we go again)
I have a kitchen floor that is pretty level other than two locations. I seem to have two joists that are bowed approximately 1/4″ upward, with a joist in between that is not. I am looking to install a new floor (wood)and would like to eliminate the humps and valley. The house is 6 years young with sheet vinyl installed. Any ideas or suggestions?
Can you slip a sawzall in there to cut off that 1/4" bow on each joist? You can drill a few small holes to get you started.
I think you might want to install a glue block next to that area, just in case the joist is weakened by that little bit of material removal. I like to use PL 400.
Hope this helps.

*Have you got bridging between the joists? Try removing it. do you know for sure that the joists are bowed up, or have the others sagged? What's below them? Crawlspace or full basement? What about lifting the joist in between the two high ones? What is your sub-floor? 3/4" plywood is recommended, have you considered replacing sub-floor in the offending area? What is your joist spacing, and span, and what was used for joists?Alot of questions, a few possible answers, but to give a good answer,(the easiest way to do the job adequately) we need to know what we're dealing with.
Materials and situations are as follows: Full basement with 7' located above duct work. 2" X 10" joists 16" O.C. with
48/24 3/4" sheathing. It is not OSB. The two joists are bowed up pretty much the 16' run (from the steel I-beam to the exterior wall). could it be that the two joists in question are mis-cuts? I put a ruler to them and they measure from 9 3/16 actual for the majority with I believe the low spot being 9" even. 1 joist next to the 9 incher is 9 3/8. The crew put dollups of construction adhesive about every 2 feet along the joists. I am able to get a piece of cardboard to slip thru at places. I think after measuring and seeing what I saw, if I had the time and money, I'd replace everything. I have neither. Does this help? JT
I'd suggest in cutting the vinyl out where the the floor joists rise and planing the area off by 1/8" or so which would make your uneveness only 1/8" which is suitable for hardwood flooring. You can buy an inexpensive 3 1/4" planer at any HI store that sells powertools. I have to think there may be a 1/4" underlayment for that vinyl which would change this scenerio quite a bit
Yes, there is 1/4 underlayment. How would this change the scenario?
