O---T---Help with squeaking floor

Well-known Member
I bought a newer home and had carped removed and high quality laminated flooring installed before moving in.
Now I have discover a few major squeaks in my floor.
I understand why the floor squeaks and some of the ways to help.
Just wish I had known this before installing the flooring-would have been easy to fix.
Anyone know of a good way to at least help with the noise?
I have easy access under floor.
 
I know it's too late for you, but for anyone else that knows ahead of time, I
ran 3 inch drywall screws through the sheathing into the joist about 12 inches
on center. Even closer in the door openings. Then went with the 1/4
underlayment. It will be hard to fix from the bottom side.
 
There is a bracket that they make that
screws to the joist underneath and then
screws to the subfloor to help hold it
tight. I would try something construction
adhesive like PL400 and try to squirt it
between the floor and joist, and then I
would use a piece of angle iron or those
blackest and try to hold it in place.
 
Have someone walk above while you are underneath listening for the squeak and watching the floor move.

Once the problem area is located, have some cedar shims ready, coat the shim with carpenters glue, hammer it in just enough to stop the movement.

If the floor raises up enough, try to get some glue between the floor joist and the sub floor.
 

No "newer" homes around me have joists - they have engineered floor trusses. If you can identify the squeaking area from underneath you might get lucky and have the squeak be in the truss, which is easy to fix. If it is between the truss and subfloor, the man who suggested shims and glue has a good idea.
 
This is an extremely difficult (nearly impossible) question to answer without actually checking things out first-hand. There are several products and procedures to help with floor squeaks, but your best bet would be to first do a little bit of investigating.

Here's "some" of the information that is not in your post that is vital in knowing how to properly fix your squeaks:
*How many layers of underlayment are there?
*Do the joints line up or are they offset?
*Are the squeaks coming from between the floor joists and underlayment, or the underlayment and the laminate flooring, or both?
*How is your laminate flooring installed? Snap together? Glued? Nailed? Is there a pad under the laminate?
*Does the laminate floor still have room to expand on all sides?

Without knowing the answers to ALL of these questions, any "fix" that is done has the potential to make the problem worse.
 
If you just had the floor put in I think it's the problem of the people that installed it. Since the flooring is installed over a sub-floor I don't think getting under it would help you much. How much of it is squeaking? Are we talking about a spot or two and you have a nail gun I would shoot a nail through the flooring and fill the hole. Just shoot the nail on an angle so it doesn't develop a squeak from that. Also if you do this put a piece of masking tape on the floor and shoot the nail through the tape. That way you can put a filler in just the nail hole.
 
There are several products, one has two pitched threads on a screw that is driven into floor and underlayment so one tightens
against the other. The other type (link) is snap off deck screws. Jim

If the squeaks are coming from the subfloor to joist connection, the only thing That I can think of is to apply PL400 Premium from the under side, as you said you had access there. Push it into the joints good and tight with a power calk gun and give it time to dry.
You did not say if the new laminate was a nail-down, or floating. If a nail-down, all bets are off. If floating, there should have been a release pad between subfloor and laminate, and hopefully the PL underneath will help.

PS. when I was doing contracting remodels and new construction, we always laid a bead of PL400 onto of joist and laid the Advantec sub floor on, and nailed it down.

Low humidity levels in home during heating
season has caused the wood to dry out causing
the wood to shrink which creates squeaks.
 
If you have good access underneath, get some shims and glue them and slide them between the joist and the subfloor in the areas that are squeaking. This will stop the movement up and down on the fasteners that is causing the squeak. sometimes they squeak where the joists hit a center bearing wall. This method is effective there as well.
 
You have a lot of fixes to try. The funny thing is in Feudal Japan the
castle's floors also temples were made on purpose to sqweak. This is
an early warning system. They were called chirping or cricket floors.
I would leave tbose marvelous floors alone.
 
Fixing a squeaky floor is a job performed before the laminate is installed. Sounds like the floor started squeaking only after the new laminate was installed. That's the reason for trying to pin this on your contractor. The only fix I can think of and it's temporary. is to get a bundle or two of shim shingles and drive them between the sub-floor and floor joists in the areas where the floor squeaks. Good luck..

Nothing was said about contractors being at fault.
Never noticed a squeak when we bought home, my fault for not repairing before flooring was installed.
