The builder says the bathroom is ready. Your crew arrives to find unfinished backer board, no approved layout, and a work order that only says tile the bathroom. Tile contractor subcontracting jobs go bad when the handoff is vague.
Win the work by making your package easy to check. Keep the job by writing down exactly what you will install, what the builder must provide, and who can approve extra work.
Choose the tile contractor subcontracting jobs you want
Decide what fits before contacting builders. A narrow target saves bid time and keeps unsuitable work away from your crew.
Write down the project types you want. Bathroom remodels. Kitchen floors. Multiroom renovations. Occupied homes or vacant sites. Include the installations you can handle, your service area, crew capacity, and the lead time needed to review a bid.
Set boundaries around work you do not perform. That may include demolition, structural repair, plumbing, drywall or backer board, or waterproofing outside your licensed and documented scope. Do not imply that your crew will sort it out after mobilization.
Run the same prospecting sequence every time:
- Find remodeling contractors whose current or completed projects match your target job profile.
- Check their service area and project type before adding them to your prospect list.
- Call the office and ask who handles tile bids or subcontractor qualification.
- Send that person your first-contact package and ask how they issue bid invitations.
- Follow up on the date you recorded instead of sending repeated general emails.
- Log the contact, response, bid invitation, submitted bid, result, and any reason the builder gave.
Review the log before approaching more builders. If the work is outside your area, beyond your installation capability, or repeatedly scheduled without enough lead time, remove that builder from the active list. Put your effort into firms that send work your crew can deliver.
When asking about tile contractor subcontracting jobs, name the project type, geographic area, and installation work you want. Then tell the estimator what information you need before you can bid.
Build a subcontractor package the builder can check
Give the estimator one current first-contact file or email containing:
- A capability summary naming the tile installations you perform
- Your service area and scheduling contact
- Your normal scope boundaries and main exclusions
- Relevant project evidence showing comparable completed work
- The name, phone number, and email address for bids
- Licensing details where they apply to the proposed work
- Insurance details where they apply or the builder requests them
Explain how to send builder inquiries. Ask for the site address, plans, finish schedule, current drawing revision, tile selections, photos, bid deadline, planned start, and estimator contact.
Keep tax forms, payment details, and vendor-onboarding documents out of the first-contact package. Send them through the builder's requested process after the builder shows interest and identifies what its accounts team needs.
Keep the package current. An old service area or dead email address makes the builder chase information before the relationship has started.
Check construction licensing requirements before representing that you can take regulated work. Find your state contractor licensing board through the USA.gov state and local government directory (opens in a new tab), ask which license class covers your proposed scope, and write down the answer. Ask the local building department which permits and inspections apply to the project. Do not guess from the contract value or project name.
Qualify the inquiry before committing bid time
Read the plans, but do not treat them as a complete scope. Confirm the address, project stage, bid deadline, intended start, drawing revision, approved selections, decision maker, and person answering technical questions.
Ask who supplies each item:
- Tile and approved overage
- Setting and grouting materials
- Trims and profiles
- Waterproofing products
- Sealants
- Protection materials
- Power and water
- Secure storage
- Waste removal
Ask who unloads and moves materials. A pallet at the curb is not the same as tile distributed near the work area.
Check the schedule against the work that must happen first. Demolition, framing, plumbing, electrical work, drywall or backer board, waterproofing, and curing can all control your start. Record the builder's readiness plan instead of assuming those trades will finish on time.
Pause the bid when the builder cannot identify the drawing revision, tile product, responsible parties, or site condition. List the missing decisions. Price after the builder answers them, or state clear assumptions and allowances where a firm selection is not available.
Inspect the site before fixing the scope
Run the builder site visit as a tile scope inspection. Walk every tiled room. Compare the site with the drawings and finish schedule.
Record:
- Every wall, floor, niche, curb, step, splash, return, transition, and penetration
- Substrate material, measured flatness, plumb, square, and visible surface condition
- Floor and shower slope, including the points and method used for each measurement
- Cracks, movement joints, changes of plane, and visible signs of movement
- Moisture or curing concerns where they affect preparation or installation
- Access routes, cutting space, storage locations, and protection needs
- The trade responsible for correcting each failed condition and the person who must approve it before tile work starts
Measure the surfaces you are pricing. Mark where dimensions differ from the plans. Photograph the room, substrate, penetrations, thresholds, access restrictions, and unfinished work. Label each photo with the room and issue.
On site, the common failure is obvious. The work order says to tile the bathroom, but nobody has assigned substrate correction or waterproofing. Do not carry that gap into the quote. Ask the builder to assign both responsibilities in writing.
Write readiness conditions. State that framing, plumbing, drywall or backer board, required inspections, access, and builder-controlled preparation must be complete before your crew starts. If workplace conditions create a safety question, check the current requirements with OSHA (opens in a new tab) and record the site control required before work proceeds.
Write the tiling subcontract scope before pricing it
Name the rooms and surfaces first. Then identify the tile product, format, pattern, orientation, joint treatment, edge finish, trim, grout, sealant, and stopping point for each surface.
Assign responsibilities separately. Use headings for tile contractor, builder, owner, and other trades. This stops one task from being assumed by two parties or ignored by everyone.
Your tiling subcontract scope should address substrate correction, waterproofing, slope, movement provisions, penetrations, protection, cleaning, and waste removal. State who supplies the materials and who approves substitutions.
Keep these buckets separate:
- Inclusions: work covered by the price
- Exclusions: work not covered
- Assumptions: conditions used to build the price
- Allowances: amounts held for undecided selections or quantities
- Builder-supplied items: products, access, services, or preceding work supplied by the builder
State what happens when dimensions, tile selections, pattern, substrate condition, access, or schedule differs from the bid information. The answer should be a written change order before the affected work continues.
Use this blank control sheet for the next builder inquiry:
Project address: [address] Builder contact: [name, phone, email] Bid deadline: [date and time] Planned start: [date or readiness trigger] Drawing revision: [revision and date] Finish schedule revision: [revision and date] Tiled rooms and surfaces: [list] Tile products and sizes: [list] Layouts and patterns: [list] Edges and trims: [list] Grout and sealant: [list] Tile contractor responsibilities: [list] Builder responsibilities: [list] Other-trade responsibilities: [list] Owner-supplied items: [list] Inclusions: [list] Exclusions: [list] Assumptions: [list] Allowances: [list] Readiness conditions: [list] Change-order approver: [name and role] Billing contact: [name and email] Billing schedule: [milestones] How retainage will be billed and released, if included: [contract terms]
For a detailed room-level breakdown, use the tile shower quoting guide to check preparation, waterproofing boundaries, tile quantities, and finish details.
Cost the accepted scope and set the terms
Price the written scope. Not the builder's project label.
Take off each surface from the accepted drawings and site measurements. Separate floors, walls, niches, curbs, trims, transitions, and other details so their work does not disappear inside one area figure.
Convert each installation method into labor tasks and crew hours. Include mobilization, preparation, layout, mixing, setting, cutting, grouting, sealing, protection, punch work, and cleanup. Add supervision and return visits where the scope requires them.
Price the specified materials, approved overage, delivery, equipment, and disposal using your own figures. Add job overhead. Then apply markup to the total job cost.
Keep undecided patterns, extra preparation, restricted access, and possible return visits out of hidden contingency. Put each uncertainty in an option, allowance, assumption, or exclusion so the builder can see what changes the price.
The framework is simple:
- Job cost = labor + materials + equipment + delivery + disposal + job overhead
- Price = job cost + markup amount
- Price = job cost × (1 + markup rate)
- Margin = profit divided by selling price
Markup and margin are not interchangeable. Markup is added to cost. Margin measures what remains from the selling price after cost.
The Oak Street house example shows the calculation. Quote Q-1847 was 1,105 sample currency units. Job cost was 850, so profit against the original quote was 1,105 − 850 = 255. Markup was 255 ÷ 850 = 30%, while margin was 255 ÷ 1,105 ≈ 23%.
Invoice INV-1847 was 1,265 after an approved 160 change order. Do not calculate profit from that invoice or combine 1,265 with the 850 job cost. The costs of the change order are unknown.
Price optional work separately when the builder has not chosen a pattern, trim, or surface. Do not bury a difficult option inside the base price and hope the easy option gets selected.
Agree the billing schedule before mobilization. Tie invoices to clear milestones or accepted work. Name the billing contact, supporting records, approval process, and how retainage will be billed and released if the subcontract includes it. Use the contractor retainage billing process to keep withheld amounts separate from unpaid change orders or disputed work.
Match tile contractor work orders to the accepted quote
Do not schedule from a one-line purchase order. Tile contractor work orders should point to the accepted quote and give the crew the current instructions for each room.
Check for:
- Project address and builder contact
- Accepted quote number and revision
- Current drawing and finish schedule revisions
- Room-by-room tiled surfaces and finish boundaries
- Preparation included in your scope and the limit of that preparation
- Approved tile, pattern, grout, sealant, edges, and trims
- Layout control points, starting lines, focal points, and approved cuts
- Material delivery and storage locations
- Work sequence and preceding-trade handoffs
- Site access hours and occupied-area restrictions
- Protection duties during and after installation
- Cleanup and waste-removal boundary
- Open selections or site decisions that still block work
- Conditions that require the crew to stop and contact the builder
- Contract price, billing contact, and change-order approver
Read the purchase-order terms against your quote. Look for wording that adds preparation, removes exclusions, changes payment terms, or makes your crew responsible for delays outside your control. Resolve the conflict before ordering materials or assigning labor.
Use the work order explainer to build a clean handoff from the accepted quote to the crew.
Hold a pre-start check. Walk the issued work order with the foreman and builder, then record any instruction that changes it. If the area is not ready, record the failed condition and ask for a new mobilization date.
Stop unpriced changes before the crew continues
Tell the crew who can request work and who can approve a change order. A site conversation is not approval unless the named person records it through the agreed process.
When something changes, stop the affected task. Record the condition, requested work, price or pricing basis, schedule effect, and approval. Update the work order or attach the approved change order before continuing.
The same rule covers a new niche, another tiled wall, extra substrate preparation, revised pattern, changed trim, material substitution, delayed access, or a return caused by incomplete preceding work.
The house example is electrical, but the document control is the same. At R. Chen, 14 Oak Street, Quote Q-1847 covered a bathroom exhaust fan and four LED downlights for 1,105 sample currency units. The ceiling was lined, and chasing was excluded. Extra cable and chasing were approved on site as a 160 change order, so Invoice INV-1847 became 1,265. These figures are a worked example, not tile rates.
The clean chain matters: quote, exclusion, changed condition, approved change order, revised invoice.
Keep site records that support handover and billing
Write a short daily note tied to the work order. Record readiness failures, instructions, delays, completed areas, material shortages, damage, and work by other trades. Label each photo with the date, room, and issue.
If another trade damages finished tile or blocks access, record the condition before repairing or remobilizing. Ask for punch items in writing with the room, location, required action, responsible party, and status. Close your assigned items and record completion.
Close the package and ask for the next fitting job
Match the final invoice to the work order, accepted scope, approved change orders, and billing schedule. Use the same descriptions and document numbers. Do not make the builder reconstruct the job from unrelated emails.
Send the completion records required by the subcontract. That may include approved product records, care information, completion photos, closed punch items, and signed site documents.
When the builder has more tile contractor subcontracting jobs, ask for the package that matches your target project type, service area, and crew window. Reuse the same inquiry form, site inspection, scope split, and work-order check.
Prepare your first-contact package and scope checklist, then send them to a remodeling builder whose work fits your crew.
