The service

Flat is a specification,
not an adjective.

Large-format porcelain is unforgiving. A slab that looks flat will not be flat enough for a 600 by 1200 tile, and the result is lippage at every joint — the edge you catch with a bare foot and cannot unsee.

Getting there means measuring the substrate against a tolerance, levelling it where it misses, and using a setting method that suits the format. That is most of the labour in a good porcelain floor, and all of the difference.

  • Substrate measured, not assumed

    Flatness checked against a straightedge before anything is ordered.

  • Movement joints designed in

    Porcelain moves. Perimeter and field joints are placed deliberately rather than omitted.

  • Setting method matched to format

    Large tiles need full coverage and often a levelling system. It is not the same job as a small mosaic.

Scope

What a porcelain installation covers

Four stages, of which only the last is what anyone sees.

Movement joints are not optional

A porcelain floor with no perimeter gap and no field joints has nowhere to go when it expands. Tenting and debonding are the result, and they are not repairable without lifting the floor.

01

Survey and preparation

  • Substrate flatness checked against the tolerance the tile format requires
  • Existing finish removal and adhesive residue treatment
  • Crack isolation or uncoupling membrane where the slab requires it
  • Self-levelling compound where flatness misses tolerance
02

Setting out

  • Layout set from the sightlines that matter, not from an arbitrary corner
  • Cuts balanced so no edge finishes on a sliver
  • Movement joint positions determined before the first tile goes down
  • Level and transition heights coordinated with adjoining finishes
03

Installation

  • Setting material appropriate to format, substrate and location
  • Full mortar coverage under large-format tiles, back-buttered where required
  • Levelling systems to control lippage across joints
  • Perimeter and field movement joints formed as designed
04

Finishing

  • Grout selected for joint width, colour stability and cleanability
  • Movement joints filled with flexible sealant, not grout
  • Thresholds, trims and transitions to adjoining finishes
  • Protection until following trades are finished

How it runs

Six stages,
one contract

Every stage before installation is what determines whether the floor is still flat and bonded in ten years.

  1. 01

    Survey

    Substrate type, flatness, moisture and any movement recorded against the format proposed.

  2. 02

    Specification

    Tile format, setting material, membrane and joint layout chosen together rather than separately.

  3. 03

    Preparation

    Removal, cleaning, levelling and membrane installation.

  4. 04

    Setting out

    Layout, cut balance and joint positions agreed before laying.

  5. 05

    Installation

    Laid with full coverage and levelling control, joints formed as designed.

  6. 06

    Grout and protection

    Grouted, movement joints sealed, and the floor protected until other trades are done.

Approvals

Mostly a specification job,
occasionally a permit one.

Replacing a floor finish is generally not permitted work in itself. What can bring a permit into it is everything around the floor — moving a wall, altering plumbing, or work in a condominium where the association has its own requirements.

In multi-storey and condominium buildings the more common constraint is acoustic. Many associations specify a minimum impact-insulation rating for hard flooring above occupied units, which means an acoustic underlayment and, sometimes, evidence of the assembly’s rating before approval.

We check the governing documents before specifying, because an acoustic requirement changes the build-up, the height and the transitions.

From first call to closeout

  • Substrate survey

    Type, flatness, moisture and movement.

  • Association check

    Acoustic requirements and approval process where applicable.

  • Specification

    Tile, setting material, membrane and underlayment together.

  • Height coordination

    Door undercuts and transitions to adjoining finishes.

  • Approval

    Where an association or permit is involved.

  • Installation

    To the specified system.

  • Handover

    Care and maintenance guidance for the actual products used.

Condominiums usually specify acoustics

Hard flooring over an occupied unit is one of the most common sources of association disputes. Check the required impact-insulation rating before you choose a tile, not after — it changes the whole floor build-up.

Nothing here is legal advice, and no approval outcome or review duration is promised. Requirements vary by municipality and by property.

Cost and schedule

What moves the number

Preparation and format drive porcelain cost far more than the price per square foot of the tile.

01

What moves the cost

  • Substrate condition

    Levelling compound, crack isolation or uncoupling membrane can exceed the cost of the tile itself.

  • Tile format

    Large-format is slower to lay, needs full coverage, levelling systems and often two people to place.

  • What comes up first

    Removing old tile and its bed is heavy, dusty work and sometimes reveals a substrate that needs more attention.

  • Layout complexity

    Patterns, diagonals and multiple room transitions all add cutting and setting-out time.

  • Acoustic requirement

    An underlayment mandated by an association adds material and changes floor height.

  • Access and protection

    Upper floors, lifts and protecting finished areas all add time.

02

What moves the schedule

  • Survey and specification

    Before ordering, because the substrate may change the choice.

  • Tile lead time

    Large-format and specific finishes are ordered, and shade batches matter.

  • Preparation

    Levelling compound and membranes have cure times that cannot be rushed.

  • Installation

    Slower per square foot for large format than for small.

  • Grouting

    After the setting material has cured, not the same day.

  • Protection period

    The floor stays protected while other trades finish.

Why porcelain floors fail.

Six causes account for nearly every failed tile floor. Only one of them is the tile itself.

01

Substrate not flat enough

The single most common cause of lippage. The tolerance tightens as the tile gets bigger.

02

Insufficient mortar coverage

Voids under a tile are where cracks start, particularly under a corner or an edge.

03

No movement accommodation

No perimeter gap and no field joints means expansion has nowhere to go. Tenting follows.

04

Wrong setting material

Format, substrate and location each affect what the adhesive has to do. A general-purpose choice is not always adequate.

05

Substrate movement

A cracking or deflecting slab telegraphs through unless it is isolated or uncoupled.

06

Moisture in the slab

Trapped moisture undermines bond. On slab-on-grade in this climate it is worth establishing rather than assuming.

What to expect

Dust first,
then patience.

Removal is the unpleasant part. Cure times are the slow part. Neither can be compressed much.

  • Removal dust

    Lifting an existing tile bed is the dustiest work in the job. Containment and extraction are standard.

  • Rooms out of use

    Each area is unusable through preparation, laying, curing and grouting.

  • Cure times

    Levelling compound and setting material both need time before the next step. Rushing them is how floors fail.

  • Door clearances

    A new build-up can change floor height, so doors may need undercutting.

  • Shade variation

    Porcelain is made in batches. Tiles are mixed across boxes deliberately so variation reads as texture.

  • Protection

    The finished floor stays covered until following trades are done.

Flatter than most people expect, and the tolerance tightens as the tile gets larger. A slab that looks fine will often need levelling compound before a large-format porcelain can be laid without lippage. We measure it with a straightedge rather than judging by eye.

Sometimes, if it is well bonded, flat and the height increase is acceptable. Often removal is the better answer, because it lets you see and correct what is underneath.

Wood-look porcelain, two kitchens.

Two kitchens with wood-look porcelain tile floors: a long run that continues into a living room and dining area, and a dark galley with a gray plank-look floor. Each caption is about the floor.

PROJECT 01

Wood-look porcelain through an open plan

A light wood-look porcelain floor runs from a kitchen with a quartzite island and farmhouse sink through a dining area, past a wood staircase, to a living room with a fireplace. The floor carries from room to room without a break, so the plank-look lines run in one direction across the whole open plan.

Scope of work

  • Wood-look porcelain laid through the kitchen
  • Plank-look tile continued into the dining area
  • Floor run to the foot of a wood staircase
  • Same tile carried into the living room
  • Tile kept flat around the island and fireplace
  • Floor held continuous across a large open plan

What to look for in the photos

Follow the plank lines. A long tile floor reads as one surface only when the joints stay straight past the island and the stairs.

PROJECT 02

Gray plank-look porcelain in a dark galley kitchen

A dark shaker kitchen with a granite island and island hood stands on a gray wood-look porcelain floor. The galley view shows the plank lines running the whole length between the cabinets, with white drawer bases breaking up the dark run.

Scope of work

  • Gray wood-look porcelain laid through the galley
  • Plank-look tile run the full length of the room
  • Floor finished to the island and hood base
  • Tile kept straight along the cabinet run
  • Floor continued toward a staircase
  • Planks cut to the cabinet bases

What to look for in the photos

Look down the galley. A long, narrow room shows any wander in a plank line, so straight joints here mean a careful layout.

Budget and schedule

Where a porcelain floor goes.

Porcelain is a moderate share. The labor and the flat substrate under it carry the rest. These are typical shares and a typical sequence.

Large tiles need a flat base, so substrate work comes before the tile is delivered.

What lies under the tile

Porcelain sits in a bed of mortar over a flat slab, usually with a membrane to absorb small movements. Each layer has to be sound before the next goes on.

Plank layouts and offsets

Long plank tiles are staggered, usually by a third at most, so the joints do not line up. A larger offset can lift edges on a bowed tile.

Flat enough for long tile

Large and long tiles need a slab with very little variation. Grinding and filling bring it within the tile maker's tolerance before setting.

More questions

Planks, offsets and haze.

What homeowners ask about plank-look tile: variation, offset, stairs, edges and cleaning.

Ask us directly
How do plank-look tiles avoid looking repeated?

Good plank-look porcelain is printed in many different faces, so no two neighboring tiles are the same. We mix tiles from several cartons as we lay, so similar faces never sit side by side. Check the number of faces on the sample before ordering, because fewer faces means a more obvious repeat.

What size of plank-look tile should I choose?

Longer planks look closer to real wood but need a flatter slab and a careful offset. Shorter ones are more forgiving. In a small room, a wide plank can look cramped, and a thin one looks busy in a large open plan. Lay a few samples on the floor before you commit.

What offset should long plank tiles use?

Many makers advise a stagger of about a third or less on long tiles, because they can bow slightly, and a half offset makes the corners stand proud. We follow the maker's guidance and check the first rows with a straightedge. Random offsets look natural but must stay within that limit.

Can porcelain tile go on stairs?

Yes. Stair treads need a non-slip surface, a nosing or a trim to protect the edge and a rise that matches the others. Risers can be tiled or painted. Because each tread is cut, stairs take longer than the rest of the floor. A rated tile and a tidy nose make the stairs safer.

What does rectified tile mean for the grout joint?

Rectified tiles are cut after firing to give straight, square edges and nearly identical sizes. That allows a narrow grout joint, which many homeowners like. A narrow joint shows every height difference, so the slab must be flat. Wider joints are more forgiving and give the floor room to move.

Will dropped pans chip a porcelain floor?

Porcelain is hard and resists scratches, but a heavy pan dropped on an edge can chip it, especially on a rectified edge. Through-body tile hides chips better than glazed tile. Keep a few spare tiles from the same batch, so a damaged tile can be cut out and replaced.

What is grout haze, and how is it removed?

Grout haze is a thin film of grout left on the tile surface after the joints are filled. It is cleaned off with a damp sponge while the grout is fresh, or a mild acidic cleaner afterwards, as the grout maker allows. Avoid harsh acids on colored grout, which can fade.

Is porcelain suitable for a lanai or screened porch?

Yes, if the tile is rated for outdoor use and has a slip-resistant surface. Choose a frost-proof, textured porcelain, and slope the slab so rain runs away. Dark tile can feel hot in direct sun. We can show samples and suggest a color that stays cooler underfoot.
