Hello,

I have very squeaky wood floors in my 101-year old house. They are tongue and groove with no visible nails. I can't think of any good way to stop the squeaking without putting screws through the face of the boards.

I've had no luck finding information about solutions for my problem.

I'm really anxious to get the floors silenced because I have a kid on the way and want to be able to walk around at night without waking he/she up.

Any suggestions?

You have 100 year old technology in that house; meaning everything was just nailed together. Old houses make lots of noises due to many years of movement, expansion and contraction, nails working loose, etc. Here are your options:
1) Remain "true" to the home. Make no change or "improvement" that would detract from it's historic value. This is what a conservator would recommend. Try simple harmless fixes like putting baby powder between the boards to see if it helps. Odds are, it won't.
2) Remove and replace the floors ( and fix the subfloors at the same time) with a similar or exact duplicate of what you now have. The most costly option but is "restores" the home and improves it. Plus makes it more comfortable to live in.
3) Don't worry about the home's historical accuracy. Fix the floors with the easiest and cheapest method possible. Trim heads screws may work well.
4) Just live with it. Most things ( and people ) that have survived for over 100 years deserve some respect and consideration. 100 yr. old things are tempermental, cranky and noisy at times. It happens with age.

One last suggeston: If the basement is not finished, screws of proper length can be added from underneath and a bead of subfloor adhesive run along the length of each joist.

Gary is right.
You may be able to take a few of the noises out, but not reasonable to think, or make efforst to, remove a significant number of the noises.

I've seem these efforts made and all the noise does is move to another location.
