Tile and Terrazzo Contractors

NAICS 238340 · Specialty Trade Contractors · SBA size standard: $19 million average annual receipts

Tile and terrazzo contractors bid on residential and commercial jobs, prepare substrates, set tile or pour terrazzo, grout and finish surfaces. For a crew that handles custom bathroom remodels, kitchen backsplashes and commercial lobby floors, the specialists turn bid requests into accurate estimates, estimates into material orders and schedules, job sites into sequenced tasks with inspections, and completed work into invoices and punch lists. Layout patterns, substrate tolerances and material waste stay with the lead tile setter.

Workflows

Bid and estimate preparation

Starts when: Receipt of a new project inquiry, plan set or request for proposal

  1. Extract square footage, linear footage and pattern details from drawings
  2. Calculate material quantities including waste for cuts and breakage
  3. Apply labor hours by difficulty and access conditions
  4. Draft the full bid proposal with scope, exclusions and schedule
  5. Assemble supporting documents for submission

Watch for: Tile patterns and terrazzo mixes must be priced accurately to prevent underbidding; Site access, stair counts and vertical transport affect labor estimates

Material ordering and inventory

Starts when: After contract award and before mobilization

  1. Finalize quantities from approved shop drawings and field measurements
  2. Select and confirm exact color lots from suppliers
  3. Draft purchase orders for tile, terrazzo aggregates, thinset, grout and setting materials
  4. Track deliveries against job schedule and storage limitations
  5. Log received materials and handle damaged or incorrect shipments

Watch for: Color consistency across multiple deliveries is critical for visible work; Heavy materials require staging plans and protection from weather

Project scheduling and trade coordination

Starts when: Contract signing and receipt of notice to proceed

  1. Build a detailed schedule showing substrate prep, setting, grouting and finishing
  2. Coordinate with general contractor and other trades for access windows
  3. Assign crew and equipment to each phase
  4. Update schedule when delays from other trades occur
  5. Flag upcoming inspections

Watch for: Substrate must be dry and flat within industry tolerances before tile or terrazzo begins; Curing times for terrazzo and grout affect follow-on trades

Field work and quality control

  1. Generate daily task list for layout, cutting, setting or finishing
  2. Create substrate inspection checklist including flatness and moisture readings
  3. Track material usage against estimate
  4. Document photos of work in progress and completed stages
  5. Prepare punch list items for final walkthrough

Watch for: Layout lines and expansion joints must follow architectural intent and industry standards; Protection of finished floors from subsequent construction activity is required

Inspection and permit management

Starts when: At each required inspection milestone and permit renewal

  1. Assemble required documentation for substrate, setting and final inspections
  2. Draft inspection request forms for the authority having jurisdiction
  3. Log results and any corrective actions required

  2. Draft invoice with supporting documentation
  3. Assemble final lien waivers, warranties and as-built documentation
