Home Depot and Lowes sell stair treads and risers that go over existing stair treads of a stair case.
1st, are these a good product, 2nd do they assist in renforcong the stairs so to stop squeaks, and are they cost effieient?
The only thing that will stop wood from squeaking, is to remove the unevenness in the wood. Remove the original tread, plane it flat, use a high quality wood putty to fill any imperfections, install the tread once again using ring shank nails with finish heads. Sand the show side of the tread smooth, stain to match the others. If the treads are worn too bad to plane flat, replace them with a hard wood to match the original, or purchase enough wood to replace all treads and risers. Use at least 5 quarter size wood. Check with your local building codes are to the minimum size.
I would never use any product from one of the low quality box stores. To reinforce the treads, do that from below the stringers. You may do that in many different methods. It is more personal preference. Covering the existing treades with some others will not stop the squeaking.

Thanks. I just could not see covering with a tread would stop a squeak or provide suitable reinforcement.
