How to stop a noisy aluminum baluster on vinyl railing system?

I have just installed a new vinyl railing system with aluminum balusters. The railings have aluminum reinforced inserts on the top and bottom rails.

When I walk on the deck I can hear the balusters vibrating (or at least it appears that way) and it echos through the vinyl railing structure.

I still have to install the stair railings and the railing on a lower platform and would like to prevent the noise prior to installing the remaining railings. Any ideas on how to stop this? Thanks!

Unfortunately this is not an uncommon problem - squeaky or vibrating noises from vinyl railing systems.

The Problem

Every manufacturer has their own system and some or more refined than others. Things which can contribute to noise emanating from the railing or baluster components range from:

poorly designed fastening components;
over sized baluster openings;
loose fittings;
too much room for metal or aluminum inserts in side the vinyl skin

The last one is the most typical culprit because a vinyl railing is usually nothing more than a metal skeleton with vinyl coverings fitted over it.

Possible Solutions

If all the connections between the rails and posts and the balusters and rails are indeed tight, it should greatly reduce movement and reduce the sliding of the vinyl cover skins on each other.

That is the first place to try to deal with the problem. Tighten everything very well.

If everything is tight but you are getting squeaking among the vinyl then it becomes tougher to fix because you would have to come up with some way of further preventing vinyl on vinyl sliding or putting a stuffing material inside or around the metal frames to keep the vinyl snug.

If the metal frame is tight, its really a challenge to fix this and is one of the draw backs of the vinyl railing products.
