A durable tile finish depends on what is below and behind it: framing, flatness, deflection, water management, movement accommodation and compatible setting materials. Federal Way publishes local building and permit resources, while Washington L&I provides contractor-registration information. Define those conditions, a scaled layout and transition details before comparing installers.
Require substrate assessment and preparation, waterproofing or moisture management where needed, tile and setting-system specifications, layout drawings, cuts and edge profiles, movement joints, transitions, protection, cleaning and closeout. Confirm permits for any broader structural, plumbing or electrical scope.
Record walls, openings, fixtures, cabinets, drains, thresholds and adjacent finish elevations. Confirm tile dimensions, thickness, pattern and grout-joint target using actual samples. A scaled layout should show focal lines and difficult cuts before material is ordered. Add realistic waste for pattern, breakage and future repairs rather than treating every layout as the same square-foot calculation.
Tile will not correct a flexible, damaged or uneven base. Identify framing movement, cracked slabs, loose underlayment, contamination, moisture and flatness deviations. State what is removed, repaired, flattened or reinforced and how suitability is checked. If investigation requires an opening, define it separately so concealed damage does not become an undocumented extra after demolition.
Show the water-management method for showers and other wet locations, including seams, corners, drains, curbs, niches and plumbing penetrations. Identify compatible products and inspection or test responsibility. Tile and grout are finish layers, not a substitute for a continuous water-control assembly. Photograph critical stages before they are covered and keep the product records.
Choose the controlling line, pattern direction and relationship to doors, fixtures and visible walls. Resolve narrow slivers, off-center drains and unequal border cuts on a drawing or dry layout. Stone variation and directional tile may require blending from multiple boxes. Mark where appearance judgment is required so an installer is not asked to improvise the most visible decisions.
List substrate treatment, membrane, mortar, grout, sealant and any sealer by intended use. Confirm manufacturer requirements for tile type, format and service condition. Define coverage checks, cure times and environmental limits. A mix of individually acceptable products is not automatically a compatible assembly; substitutions should be reviewed and approved in writing before installation.
Locate perimeter and field movement accommodation appropriate to the installation and existing building joints. Flexible sealant belongs at designated changes of plane and other movement locations rather than grout forced into every joint. Detail edges, stairs, thresholds and changes to wood, carpet or resilient flooring. Transition height and exposed profiles should be known before the first tile is set.
Federal Way's Building Division and Permit Center publish local project resources. Tile replacement alone may differ from a remodel that moves plumbing, changes walls or alters electrical work. Confirm the full scope and address with the city, then assign applications, inspections and regulated trades. Verify the installer's legal business through Washington L&I and keep the result with the agreement.
Review alignment, lippage within the selected assembly, joint consistency, edge finish, hollow or damaged areas and sealant transitions before final payment. Confirm cure and cleaning instructions before traffic or water exposure. Retain batch information, extra tile, product data, photographs and warranty terms. Protect finished work from other trades instead of expecting final cleaning to repair impact damage.
Describe the project once and we match it with vetted local pros who actually do this work — you choose who to hire, or nobody at all.
The city Building Division provides permit, plan-review and inspection resources.
Federal Way provides a municipal point for project applications and permit information.

| Decision | Incomplete scope | Decision-ready scope |
|---|---|---|
| Substrate | Install over existing surface | Flatness, soundness and preparation stated |
| Wet area | Waterproof as needed | System, seams, penetrations and test assigned |
| Layout | Center tile in room | Reference lines, focal points and cuts shown |
| Materials | Tile and grout included | Exact products, colors and compatibility listed |
| Movement | Caulk corners | Movement locations and sealant specified |
| Closeout | Clean and finish | Protection, cure time, care and records supplied |
Separate demolition, disposal, substrate repair, flattening, water management, tile, setting products, profiles, labor, transitions, protection and closeout. Material size, pattern, access, cut density and wet-area detailing change effort. Use written unit prices only for clearly defined concealed repair and approve scope changes before they are covered.
Only after the existing assembly is assessed for soundness, bond, flatness, height and compatibility; removal may be the more reliable scope.
Do not rely on grout as the water-control system. Wet areas need a defined compatible assembly behind or below the finish.
Before setting begins, using actual dimensions and samples to resolve focal lines, border cuts, fixtures and transitions.
Large or rigid finishes follow the base; uneven substrates create alignment, coverage and lippage problems.
It depends on the full scope. Confirm with the city when plumbing, electrical, structural or broader remodel work is involved.
