Bvflooring
We've almost completed a wholesale renovation of the basement in our 1959 ranch/rambler. One of the issues we wanted to address was the squeaky oak floors on the first floor of the house. We figured that the squeaks could be eliminated (once the ceiling in the basement was open) by driving screws through the sub-floor into the wood planks, thus strengthening the connection between sub-floor and floor. But no matter how many screws we used, the squeaks persisted. So now I'm really stuck. My only remaining hypothesis, which I'll be testing next week, is that the original floor was installed too tightly to the wall, and is therefore slightly bowed in the center and unable to "relax" enough to sit flush against the sub-floor. Perhaps once we eliminate the pressure (by shaving off the ends of the boards against the wall), the boards will relax and the screws will hold our floor steady enough to eliminate the squeaking.

But I have no idea whether (a) this hypothesis is right, or (b) whether there's some other explanation for such persistently squeaky floors. I'd appreciate ANY ideas about what the problem is, and how to solve it!

Thanks.

most sqeaks come from wood against wood movement, ot wood riding up and down on a nail.

what you need to do is screw directly into the floor joist through the subfloor, to pull the subflooring that may be loose tight to the joist to stop movement causing the squeak.

alternately, lack of expansion may indeed be a problem so releasing that tightness could help.

There is no way we can tell you what specifically is causing the squeaks. The sound might lend some answers, specifically where the sound is coming from.

you should be able to tell by the sound if it is a flooring or subfloor squeaking.

if in the flooring itself, please DO release any tightness in the perimeter BEFORE screwing it down.

Your suggestion seems to be that we need to fix our squeaky floor by screwing the floor into the subfloor (and joist) from ABOVE the floor, rather than from below. This will make the floor look extremely unsightly, will it not? We're talking about a VERY squeaky floor, where the squeaks don't seem to emanate from a single location. They're everywhere. And I don't want to end up with a hideous-looking floor with hundreds of holes in it! Help!

Have some one walking across the floor while you examine the sub-floor from below.

And when you find a sqeaky area have them continously step into and out of that area.

Closely look at the joist/subfloor to see if there is any movement. It does not take much.

If you have movement in that area then then the sub-floor can ride on a nail and squeak.

if that is the problem there are special brackets available that screw into the joist and sub-floor.

Another fix it so take some shims and coat them with glue and drive them between the joist and sub-floor. Not hard enough to cause the space to open up more. Just enough to fill gap.

This has already been done... over and over again. We are completely unable to fix these squeaks by simply strengthening the connection between floor and sub-floor. Shims have been used. Hundreds of screws have been installed.

no .. what i am saying is that you have to discern the cause first and the location of the squeaks.

the squeaks are either in the flooring itself OR in the subfloor system.

if in the flooring itself you need to relieve any preassure points expansion may have caused or you wont get rid of the squeaks, then AFTER relieving the expansion pressure points, if there are still squeaks, renail as needed in the squeaking areas.

IF the squeaks are in the subfloor system then the sufloor need to be properly anchored to the joists system to prevent the squeaks in the areas that sqeak.

This isnt a perfect science ... something is wrong with your floor system or subfloor system causing it, which needs to be addressed to be able to rectify it. Just slapping screws in whilly nilly isnt going to be a long term solution.

Discern cause is nubmer one.

THEN, rectify the cause whether the cause be expansion of the flooring system, improper nailing paterns or effect, structural instability of the subfloor system, or structural instability of the joist system, etc, etc.

This can be a tedious and frustrating affair for even the most seasoned craftsman.

You may very well want to outsource it.

Ah, now I think I understand. Whether or not it's fixable or not is another question... but thanks for the advice.
