Questions to Ask a Tile Installer
You do not need to know how to install tile to hire well. You need to ask questions specific enough that a vague answer becomes obvious. These are those questions, grouped by the conversation you are having.
About the business
- How long have you been doing tile work, and is tile your primary trade?
- Are you licensed and insured for the scope of this project, and can I see current documentation?
- Will you be doing the work, or a crew? Who is on site day to day?
- Can you share addresses or photos of recent projects similar to mine?
- Do you carry workers' compensation coverage for anyone on site?
About the estimate
- Is this a fixed price or an estimate, and what could change it?
- What exactly is included — demolition, disposal, prep, trim, fixture reset, cleanup?
- What is explicitly excluded?
- Who supplies tile, mortar, membranes, grout and trim, and are those materials named?
- How much tile overage should I order for cuts, waste and future repairs?
- How are change orders handled, and will anything proceed without my written approval?
About the actual work
- What is under the current surface, and how will you check its condition?
- How will you evaluate whether the floor is flat enough for the tile I chose?
- In the shower, which waterproofing system will you use, and how are the corners and the drain detailed?
- Will the shower pan be a mortar bed or a pre-formed assembly, and why that choice here?
- How will you establish layout, and where will cut tiles and pattern seams end up?
- What grout are you recommending, and where will flexible sealant be used instead of grout?
- Are movement joints needed in this area, and where will they go?
About logistics
- When can you start, and how many working days do you expect on site?
- Which days will nothing appear to happen because something is curing?
- How will you control dust, and what gets covered or protected?
- Where will materials and debris be staged?
- How long after completion before I can walk on it, use the shower, or move furniture back?
- What does daily cleanup look like, and what does final cleanup include?
About afterwards
- What does your labor warranty cover, for how long, and is it in writing?
- What are the manufacturer warranties on the materials being used, and what would void them?
- How should I clean and maintain this tile and grout?
- Does the grout or tile need sealing, and if so how often?
- Will you leave extra tile with me for future repairs?
- If something looks wrong in six months, what is the process for getting you back out?
Answers worth paying attention to
A good installer will happily explain how they intend to prepare the substrate and, in a wet area, name the waterproofing system they use. Vagueness on those two subjects is the most reliable warning sign in this trade, because both are invisible once tile is on.
Others worth noting:
- A schedule with no curing waits in it means a step is being compressed.
- "Grout will keep the water out" — grout is not waterproofing.
- A large cash deposit before any work, or pressure to decide the same day.
- No written scope, or a one-line quote for a shower.
- Reluctance to state what the labor warranty covers.
Once you have the answers, compare estimates using the checklist in the cost guide, and see how this site connects you with local professionals.
Hiring questions
Two or three is usually enough to see where the middle is. More than that tends to add confusion rather than information, especially if the scopes are not written the same way.
Not automatically — but find out why it is lower. In most cases it is scope, not efficiency: demolition, disposal, leveling, waterproofing or trim pieces have been left out, or a thinner prep approach is assumed.
A deposit is common, particularly when the installer is supplying material. What matters is that it is proportionate, documented in writing with what it covers, and not a large share of the total before work begins.
The scope of work, what is included and excluded, materials and who supplies them, the waterproofing approach in wet areas, approximate schedule, payment terms, how changes are approved and priced, and the labor warranty.
Ask for current documentation and confirm it independently rather than accepting a photo of a card. Requirements vary by the scope of work and by jurisdiction, so ask what applies to your specific project and check with the relevant state or county authority.
