This project is to show how not to install retro treads and what was required to correct that situation  in order to install a safe and substantial railing system.

Cusparian removed the top tread and riser on the lower level, and revealed three more issues;

  1. The flooring installers had used a water based adhesive between the new treads and the original unfinished treads which is wrong because mold will form between the unfinished wood.
  2. The center support stringer under the lower stair assembly had been cut compromising the structure of the lower steps.
  3. The flooring installer had used clear silicone on every seam making painting of the stringers and risers impossible.

The owners contacted their general contractor with these issues and it was agreed that they would use my services to remove, repair and replace the work the flooring contractor had done.

The following pictures show the structural reinforcement  to the connection between the original top tread and the intermediate landing with 12” screws  through the second tread into the face joist in the landing all the way across to repair the cut center stringer. Also the filling in from all the voids created by the use of a reciprocating saw to trim the existing tread nosings. Ten three inch screws were screwed through the original treads into the stringers for reinforcement and elimination of any squeaking in the stairs.

Once the original structure was prepared, and shorn up and filled ready for primer and paint on all surfaces except the treads and rails, the treads, risers, and railing system was installed and finished along with redoing the top landing where the lump had been.The owner was going to do the final painting which wasn’t done when I left.
