Inspect the base before selecting a method
Record the existing covering, substrate, flatness, cracks, movement, contamination and moisture evidence. Define what must be removed and who decides whether the exposed base can receive tile.
Hillsboro, OR
Plan tile and stone in Aloha, OR as a complete surface assembly
Tile performs only as well as the substrate, water-control system, setting materials and movement details beneath it. For an Aloha address, confirm jurisdiction with Washington County before assigning permits, identify plumbing or electrical changes separately, and make bidders price the same layout and finish boundary.

Quick answer
What belongs in an Aloha tile or stone proposal?
Require substrate findings, removal and preparation limits, wet-area waterproofing, exact products, approved layout, transitions and movement joints, regulated-trade responsibilities, occupied-home controls, cure time and closeout records.
Design wet areas from the drain outward
A shower or other wet assembly should identify slope, drain connection, membrane, seams, corners, curb, niche and every penetration. State the test and acceptance point before tile covers the waterproofing.
Approve layout with the actual material
Use delivered tile or stone dimensions to resolve focal lines, pattern direction, grout width, edge cuts, openings and variation. Photograph the approved dry layout or sample area.
Name compatible installation products
List patching, underlayment, membrane, mortar, grout, sealant and sealer by intended use. Require written approval for substitutions and follow product cure and environmental requirements.
Plan movement and transitions
Identify building joints, changes of plane, perimeters, thresholds and adjacent floor heights. Assign flexible-joint and edge profiles rather than leaving them to field improvisation.
Confirm Aloha permit boundaries
Aloha includes unincorporated Washington County properties. Tile replacement differs from moving plumbing, altering framing or adding electrical work, so confirm the parcel and complete scope.
Protect an occupied home
Define dust containment, debris path, fixture removal, material storage, water shutoffs, adjacent-finish protection and daily cleanup. State when the space can safely return to service.
Close out after cure and inspection
Review alignment, joint consistency, edges, sealant, transitions and damage after required cure. Keep extra material, batch information, photos, approvals, care guidance and warranties.

Older painted surfaces need a separate check
Covered renovation disturbing pre-1978 painted surfaces may fall under EPA lead-safe renovation requirements.

Frequently asked questions
Can new tile be installed over old tile?
Only after the existing bond, flatness, height, movement and product compatibility are assessed and accepted.
Is grout the waterproofing system?
No. Wet areas need a defined water-control assembly behind or beneath the finish.
Who handles permits in Aloha?
Confirm the exact property. Washington County may serve unincorporated Aloha addresses, while trade work can follow separate approval paths.
When should the layout be approved?
Before repetitive setting, using actual material dimensions, planned joints, focal lines and edge cuts.
What if the subfloor is not flat?
Document the condition and approve a preparation or repair method before installation; do not hide it in a general allowance.
Can the room be used immediately?
Follow the specified membrane, mortar, grout and sealant cure requirements before traffic or water exposure.
How do I verify the contractor?
Search the exact legal business through Oregon CCB and verify regulated trades separately.
What should I retain after the project?
Keep extra tile, batch and product data, layout approval, photos, permits, care instructions and warranties.
