I have a friend with a floor problem.
He had a home for sale and while it was for sale there was a water leak in the line to the refrigerator. The maple floors were removed and replaced with mullican pre-finished maple. The new floors were stapled down to the 3/4" osb.
Roofing paper was used on top of the 3/4" osb, but i don't know if it was 15 pound or 30 pound.
The problem now is that floors are squeaky as hell. You can see some pieces of floor move up and down as you step on it.
My friend hasn't paid the general contractor yet. He contacted them and the flooring subcontractor and they first told him the humidity was too high. Mind you this is in iowa in the winter. They took a humidity reading and decided the humidity was too low and it should be brought up to 40% to see if that would stop the squeaking.
He turned on the humidifier and took it up to 40% and beyond and kept it there for 3 weeks and it had little or no effect.
I'm thinking the 3/4" osb was compromised when the flooding took place and also when the ruined floor was removed.
We don't know if the installers put in a staple every foot or every 6 inches.
Any thoughts on how to proceed?
My friend is thinking about having them screw it down from below and has even ordered some magnets to identify the problem spots. But there are a lot of problem spots.
Total square footage is about 400 square feet and meets up with the front door, staircase upstairs, staircase downstairs, and carpeting in other rooms. This area is comprised of the entry and kitchen.
He got a new kitchen out of the flood somehow too, so these are sitting on the new floor.
Thanks in advance for the help.
