If You Wait Until It’s Finished to Check the Work, You’re Already Too Late.
Herringbone is unforgiving.
If the wall is not flat, the layout starts drifting, grout joints become inconsistent, tiles sit proud or recessed, and the whole installation can look off under lighting.
ANSI, TCNA, and manufacturer requirements address things like substrate preparation, lippage, movement joints, mortar coverage, and proper installation tolerances.
But standards only matter if installers are trained to recognize problems before they become failures.
A good installer should understand:
* flatness
* layout and pattern control
* lippage
* grout consistency
* coverage
* movement accommodation
* when to stop and correct something
And this is why communication during the job matters.
Not micromanaging. Not hovering.
Just checking in:
Is the wall flat enough?
Is the pattern staying true?
Are we fighting something that needs to be fixed now?
Because fixing a few square feet during installation is a lot cheaper than ripping out an entire finished backsplash.
Training catches problems early.
Communication keeps them from growing.
Quality control should happen during the installation, not after the failure.
