What Information Helps Us Prepare a Renovation Estimate?
Photos, measurements, access, product choices, and clear project notes help make your estimate request useful.
Tile Backsplash
Tile and Backsplash Installation
Tile layout, substrate and edge details matter as much as tile choice, especially where splash exposure changes the assembly.
Renovation1.ca · Published
Starting condition
A kitchen backsplash or bathroom wall is ready for a new finish, or old tile must be removed. Outlets, cabinets and corners interrupt the field.
The problem
Tile placed over weak paint or uneven backing may loosen or look crooked. A shower wall needs an appropriate waterproof system beneath the tile; grout alone cannot provide one.
What to inspect
- Check substrate soundness and flatness
- Identify wet versus ordinary splash exposure
- Measure tile module and visible centrelines
- Map outlets, edges and penetrations
- Check cabinet and countertop junctions
- Confirm selected tile and manufacturer system requirements
Recommended approach
Prepare the substrate for the selected setting system, plan cuts around visible edges, and use a complete waterproof assembly wherever the location requires one. Confirm outlet or fixture adjustments with the appropriate trade.
Typical scope
Preparation
- Protect counters and dry-plan tile layout
Removal
- Remove old covering where agreed
Installation
- Prepare substrate and set tile with compatible materials
Finishing
- Grout and finish movement joints and exposed edges as specified
Cleanup
- Clean tile and remove installation debris
Exclusions
- Shower waterproofing, concealed damage and electrical changes must be explicitly scoped
Materials
- Selected tile and edge profiles
- Compatible setting material
- Grout and suitable joint sealant
- Wet-area system components if applicable
Work sequence
- Assess substrate and exposure
- Confirm layout and edge treatment
- Prepare approved surface
- Set tile and allow required curing
- Grout, finish joints and inspect
Possible complications
- Uneven wall alters cuts
- Outlets interrupt the pattern
- Old tile removal reveals damaged backing
Quality checks
- Tile bonded to suitable substrate
- Pattern and edge cuts follow agreed layout
- Joints are consistent for the chosen tile
- Movement and wet-area details follow selected system
- Finished surface is clean
Expected result
The aim is a durable, orderly tile surface suited to its exposure. Any wet-area waterproofing is specified as an assembly, never inferred from tile or grout.
What changes the scope
- Substrate condition
- Wet-area requirements
- Tile format and pattern
- Edges, outlets and penetrations
