Tile Installation Customer Won’t Pay: It Is Usually the Lippage

Short answer: When a tile installation customer won’t pay, the balance is usually being withheld over quality rather than cash — lippage, grout lines, or a floor that “isn’t flat.” Check that first, because published ANSI tolerances may already settle it. Then find out if you are owed by the homeowner or by a general contractor holding retainage. Stop only at a cured, closed boundary, never mid-field. Preserve lien rights on the short subcontractor deadline, then use small claims.

Tile is different from the trades around it in one way that changes the whole conversation: the customer is standing on the work every day, in raking light, with nothing else to look at. Almost no other finish gets inspected that hard. So a withheld tile balance is rarely a customer who cannot pay. It is a customer who has decided something is wrong, and the money is the only lever they have. That means the first move is not a demand letter. It is finding out what they think they are looking at.

What is the customer actually disputing?

Ask, specifically, and get it in writing before responding. Tile complaints cluster into a short list, and each one has a different answer.

The complaint	What it usually means	Where the answer lives
”The edges aren’t level”	Lippage between adjacent tiles	Published tolerance, measured with a straightedge
”The floor isn’t flat”	Substrate deflection or slab variation	Whose scope the flattening was in
”The grout lines are crooked”	Layout, or tile warpage in a large-format run	Layout lines and dry-lay photos
”The grout is a different color in places”	Cure conditions, water in the mix, or efflorescence	Grout batch and cure documentation
”There’s a hollow sound”	Coverage under the tile	Mortar coverage standard for the setting
”It cracked”	Movement, missing joints, or substrate	Movement joint layout and substrate spec
”It wasn’t what I picked”	Dye lot or a customer-supplied material change	Signed selection sheet
Nothing specific, just silence	A cash problem, or a GC problem	The next section

Get the complaint named. A customer who cannot name it usually does not have one, and an operator who starts arguing about workmanship before knowing what is alleged has already conceded that something is wrong.

Where did the money actually stop?

Tile setters work in two positions, and the money behaves nothing alike.

Position	Who owes you	What it looks like
Direct with the homeowner	The homeowner	A quality dispute, a change-order dispute, or genuine cash trouble
Sub to a remodeler or GC	The contractor	Often not about your work at all — the owner is slow, or the GC is float-financing
Sub with retainage held	The contractor, later	Five to ten percent held to closeout; this is not nonpayment
Builder on new construction	The builder	Draw schedules, punch lists, and long cycles
Property manager or commercial	The management entity	A missing purchase order number

That last row is usually clerical rather than adversarial, and it responds to the routing habits in how to get clients to pay rather than to anything in this article.

The retainage row matters because it looks identical to being stiffed and is not. Retainage releases at substantial completion or at a defined milestone, and chasing it as if it were a refusal burns a relationship that generates work all year. Ask which it is before deciding anything.

The second row has a trap attached: when the homeowner is not your customer, they may have already paid the GC in full. Your claim runs against the contractor, and in most states preserving lien rights from that position requires a notice the direct contractor never has to send.

Which phase am I in, and can I stop here?

Tile is the rare trade where the stopping rules are dictated by chemistry. Thinset has an open time measured in minutes and a pot life measured in an hour or two, and cured mortar ridges have to be mechanically ground off before anyone can continue. A mid-field stop does not pause the job — it creates demolition.

Stage	Can you stop?	What stopping means
Nothing started, deposit unpaid	Yes, cleanly	Do not order tile, do not book the crew
Demo done, substrate open	No	The room is unusable and often the only bathroom
Backer board or uncoupling membrane down	Yes, at a boundary	Floor is walkable, nothing is exposed to water
Waterproofing applied, flood test not run	Run the test first	Leaving an untested membrane hands the next person your liability
Thinset spread, tile not set	Never	Open time is minutes; cured ridges must be ground off
Field set, not grouted, wet area	No	Open joints let water into the setting bed
Field set, not grouted, dry area	Yes	Stop at the end of a plane, protect the surface
Grouted, not sealed or caulked	Yes	Low risk, and it is real leverage
Punch list only	Little leverage left	The lien is the tool now

When you do stop, notify in writing, cite the payment term you are suspending under, and state what condition the work is being left in and what has to happen before it resumes. A crew that simply stops showing up hands the customer an abandonment narrative — and in a tile job, an abandonment narrative plus an open shower is an expensive story.

Do published tolerances back me up?

Often, yes, and this is the strongest card a tile setter holds. Tile installation has written industry tolerances, and most homeowners have never heard of them.

Under the ANSI A108 series, floor lippage between adjacent tiles is allowed within a stated amount plus the tile’s own inherent warpage: for grout joints from 1/16 inch up to under 1/4 inch, the allowance is 1/32 inch plus warpage, and for joints of 1/4 inch or wider it is 1/16 inch plus warpage. Substrate flatness has its own numbers — for tile with any edge 15 inches or longer, the standard calls for maximum variation of 1/8 inch in 10 feet and no more than 1/16 inch in 2 feet, with a looser allowance for smaller tile. Industry consultants publish plain-language summaries of what counts as acceptable lippage, and having one on your phone changes the tone of the conversation immediately.

Two things have to be true for the standard to help you.

First, your contract has to point at it. One sentence — installation to be performed in accordance with the applicable ANSI A108 standards and TCNA methods — turns a subjective argument into a measurable one. Without it, you are two people with opinions.

Second, the substrate scope has to be written. This is where tile setters lose. Large-format tile is unforgiving of a floor that is out of plane, and self-leveling or floating a slab is a separate operation with real material and labor cost. If that line was quoted, declined by the customer, and installed anyway over their objection, you need the declined line in writing. If it was never quoted, the lippage argument may genuinely be yours — an estimating omission that arrives months later disguised as a payment dispute.

Bring a straightedge and a feeler gauge to the walkthrough. Measure in front of them. A number ends the conversation faster than any explanation.

Do I have lien rights as a tile setter, and what changes under a GC?

Setting tile is an improvement to real property, so lien rights generally exist. The paperwork is what changes with your position, and subcontractor deadlines are the ones that catch people.

Texas is a clear example of how tight a sub’s calendar runs. On residential construction, an unpaid subcontractor’s notice of claim to the owner and the original contractor has to be sent no later than the 15th day of the second month after the month in which the labor or materials were furnished — nonresidential gets one extra month. The rules sit in Property Code Chapter 53, and Texas A&M’s real estate research center keeps a readable summary of mechanic’s and materialman’s liens. Two months from the month you worked is not long when a GC is still telling you the draw is coming.

Your position	Notice burden	Practical habit
Direct with the homeowner	Usually lighter or none	Diary the recording deadline from your last day on site
Sub to a GC or remodeler	Notice to owner and contractor, on a short monthly clock	Send it on schedule for every job, not just the worrying ones
Multi-phase job with a gap	Deadlines can run from each furnishing period	Do not assume the punch-list return trip resets the clock

Recording deadlines run from last furnishing, and tile work has a habit of trailing off — the field goes down in March, the customer delays the trim selection, and you come back in May for the accent band. Do not assume the May visit restarts anything. Get advice on which date governs in your state before relying on it.

What is the balance made of when the customer supplied the tile?

This is common in tile and it changes the shape of the claim. When the homeowner bought the tile, your unpaid balance is labor plus setting materials — thinset, backer board or membrane, waterproofing, grout, edge profiles, sealant — and none of it is a claim for the tile itself.

It also changes who owns the shortage. Waste factors are not optional: a straight-set field typically runs 7 to 10 percent, and a diagonal or herringbone layout runs 15 to 20 percent because every perimeter tile becomes two cuts. A customer who bought exactly the measured square footage will run short mid-job, and the dye lot will be gone. That delay is not yours, but it will be argued about, so put the required waste factor on the estimate in writing before a single box is ordered.

And be clear about the warranty boundary on the invoice: you warrant the installation, not the material somebody else selected and purchased. Chipped edges, warpage beyond the manufacturer’s own allowance, and a discontinued lot are the supplier’s problem. The way to make that stick is to have said it on the document, which is part of the field list in what to include on an invoice.

Does small claims fit a tile balance?

Sometimes, and the split runs cleanly by room.

The job	Realistic venue
A repair, a regrout, a shower pan patch	Small claims
A single bathroom floor or a backsplash	Small claims in most states
A full bathroom, floor and walls, with a curbless shower	At or over many state caps
A whole-floor large-format installation	Lien first
Multi-unit or commercial	Lien, then counsel

State ceilings vary widely — roughly $2,500 to $25,000 depending on where you are, with Michigan around $7,000 and Georgia’s magistrate courts around $15,000 — so confirm your state’s current figure and check whether your business entity may file directly or has to use a separate commercial track. You can normally waive the amount above the cap to stay in the venue, and on a mid-size bathroom that is often the right trade.

What in the job file actually wins this?

Photographs taken at the moments nobody wants to stop for, and quantities recorded when they were still visible.

• Substrate condition before anything went down, with straightedge readings and the date. This is the single most valuable photo in tile work.
• The declined line, if flattening or a membrane was quoted and refused, in the customer’s own words.
• Dry-lay and layout lines, for the pattern and the starting point.
• Mortar coverage, with a tile pulled and turned over during the set.
• The flood test, running, with a timestamp.
• Square footage by surface, floor, wall, and ceiling listed separately, since they are not the same price and a lumped total invites a dispute.
• Cut count on small rooms. A 40-square-foot bathroom has low area and heavy cutting, and hourly yield collapses. If the price reflected that, the reasoning should be on the paperwork, which is where how tile setters send estimates does the real work.
• Every change order, signed, especially substrate repairs found under the old floor.

Keel holds that file on the phone and only on the phone — no account, no bank connection, no cloud, no login, and an App Store privacy label that reads Data Not Collected. For a trade that bills in phases, the practical part is that a progress invoice for the waterproofing stage gets built on site in about a minute with your numbering, logo, and brand color, and the payment link renders as a QR code the homeowner scans before you move to setting. Phased billing is what prevents the entire job from becoming one unpaid balance. Tile, thinset, membrane, and blade receipts get photographed at the supply house and read on-device by Apple Intelligence, so the material cost behind a disputed line has paper behind it. Freeboard shows cash minus tax reserve, minus committed invoices, minus a buffer, which is what keeps a held retainage from reading as spendable money. Free is $0 with unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 lifetime purchase, not a subscription. How long to keep all of it afterward is in how long to keep tax records.

Frequently asked questions

The customer says the tile is uneven. Do I have to fix it?

Only if it exceeds the applicable tolerance. Under the ANSI A108 series, floor lippage of 1/32 inch plus the tile’s inherent warpage is allowed with grout joints from 1/16 inch to under 1/4 inch, and 1/16 inch plus warpage with wider joints. Measure it in front of them with a straightedge. If it is inside the standard and your contract references the standard, the discussion is over.

Can I remove the tile if the customer won’t pay?

No. Tile bonded to the substrate is part of the building, removing it destroys the substrate and often the plumbing and waterproofing behind it, and self-help converts a collection matter into a claim against you. Your remedies are the written demand, a mechanic’s lien, and court. Withholding the trim, the sealant, or the final caulk is legitimate leverage; demolition is not.

Can I stop tiling in the middle of a bathroom?

Not mid-field. Once thinset is spread it has minutes of open time, and cured ridges have to be ground off before anyone can continue. Stop at a cured, closed boundary — after the membrane and a completed flood test, or at the end of a finished plane in a dry area — and notify the customer in writing citing the payment term. Never leave a shower open or an untested waterproofing membrane.

How long do I have to file a lien as a tile subcontractor?

Less time than a direct contractor, and the clock usually runs monthly rather than from your invoice. Texas residential work, for example, requires a subcontractor’s notice by the 15th day of the second month after the month the work was furnished. Recording deadlines then run from last furnishing. Diary both dates on the day you start, and do not assume a punch-list return trip resets them.

The homeowner bought the tile and it ran short. Who pays for the delay?

They do, but only if the waste factor was in writing before ordering. A straight-set field normally needs 7 to 10 percent overage and a diagonal or herringbone layout 15 to 20 percent, because every perimeter piece becomes two cuts. Put the required quantity on the estimate. Your warranty covers the installation, not material somebody else selected, and the invoice should say so.

Is retainage the same thing as not being paid?

No. Retainage is a contractual holdback, commonly five to ten percent, released at substantial completion or a defined milestone. Treating it as a refusal damages a relationship that produces steady work. Ask the contractor which it is, get the release date in writing, and only escalate if the milestone passes. Keep it out of your spendable cash figure until it lands.
