Tile does not fail. What is under it fails.
Cracked grout lines and loose tiles almost never mean the tile was bad. They mean the floor underneath moved, and tile does not move.
So the work happens before any tile gets set.
Deflection
A tile floor needs a stiff subfloor. Bounce in the joists translates directly into cracked grout, and on a natural stone floor it cracks the stone itself. On an older house, particularly the mid-century stock around Murray and Millcreek, joist spans were not designed with heavy tile in mind.
We check deflection before we quote. If the floor needs blocking or an additional layer of subfloor to carry tile, that goes in the number up front. It is not a change order we spring on you in week two.
Uncoupling and waterproofing membrane
Concrete and tile expand at different rates. An uncoupling membrane lets the slab move underneath without dragging the tile along with it, which is what keeps a crack in the slab from becoming a crack straight through your floor.
In a shower or a bathroom, waterproofing is a separate job from tiling and it is the one that protects the house. We do it properly, with a bonded membrane, taped seams, and preslope where there is a drain. Water that gets past a tile floor does not announce itself. It rots the subfloor quietly for two years.
Large format
Anything over 15 inches on a side is large format, and it is far less forgiving. The substrate has to be flatter, the mortar has to be back-buttered for full coverage, and lippage between tiles becomes visible at a glance. We use a leveling system on large format rather than eyeballing it.
Grout
Grout choice is a maintenance decision more than a look decision. Cementitious grout is easier to work with and easier to repair. Epoxy grout is far more stain resistant and is the right answer for a commercial kitchen or a mudroom, but it is unforgiving to install and it costs more in labor.
We will tell you which one your room needs.
