While waiting for the wood block's adhesive and finishing to completely dry as mentioned in the previous post, you can do a bit of refurbishing on the other side of the damage - and that is the PVC door itself. With the door now detached, you can easily work on it by resting it on the side where door knob is installed.

The refurbishing required on the PVC door is basically covering the unsightly screw holes that remained after the PVC door hinge was relocated. I decided against putting another block of wood on this one because the door's construction and material seem stronger than that of the PVC door jamb.

In the picture below, you can see 2 sets (not just 1) of screw holes in the previous location of the hinge.

I could only assume that the contractor did a hit-or-miss on this bathroom door installation. My guess is that the contractor made a mistake in aligning the hinge guide (etched dotted line on the hinge) with the PVC door edge. So the contractor pulled out the screws and moved the hinge slightly outwards so the line and the edge would align. Of course I didn't see this.

It was only when I raised the hinge further up did I see the screw up (pun intended!) with the two sets of screw holes instead of one.

Covering the Screw Holes

With a sealant in a caulking gun, position the tip of caulking gun's nozzle INSIDE the screw hole.

Attempt to pump in as much sealant as you can until excess sealant oozes out of the screw hole. Move on to the next screw hole and do the same thing.

Smear the excess sealant in and around the burrs of the screw holes. The burrs are the rough edges of the holes.

Do the above procedures to the screw holes for the rest of the hinges.

Let all the sealant dry.

Finishing the Patched Holes

With a flat screwdriver, spatula or putty knife, scrape away excess sealant material that has dried on the PVC surface. The PVC surface is very smooth and this sealant scrapes away easily.

Lightly sand the remaining bumps and rough edges with a sandpapaer as shown below.

As was done on the door jamb, paint the worked area with white paint and let it completely dry.

When the white paint has dried, clean the door by brushing and washing it with soap and water. It's easier to clean the door prior to reinstallation.

Reinstalling the PVC Door

When both work on the PVC Door Jamb and PVC Door have been completed, you'll need an assistant to put back the PVC door into the jamb.

Have the assistant lift and bring the door close to the door jamb. While holding the door edge, match the 2 parts of the hinges (male and female) together. Ensure the hinge guides are properly aligned with the door and jamb edges. If misaligned, the hinge and the pins may likely be deformed when the door is swung.

Bring the uninstalled hinge closer to the jamb and mark the hinge holes. Using a Phillips-type screwdriver, work the screws in as shown below.

After reinstalling, test the door hinges by swinging the door. Apart from the swiveling parts of the hinges, no other parts should be moving unnaturally. Any jerky or popping movement will likely damage the hinge.

Finally, fully close the door to ensure that the latchbolt correctly engages with the strike plate. Adjust the strike plate's position as needed.
