Tile installation in Westminster is planned as a durable finish system, not as a cosmetic layer laid over unanswered questions. Apollo Construction begins with the room, substrate, water exposure, planned changes, responsible authority, and permit holder so the selected tile is supported by a buildable sequence.
This guide is for planning. It does not replace the issued permit, the authority having jurisdiction, or a manufacturer’s written system instructions. We confirm the final scope before demolition because a tile-only replacement and a bathroom remodel can have different local requirements.
Westminster has used the 2021 International Codes since June 1, 2024
Westminster states that the 2021 International Codes have been in effect since June 1, 2024 and that the City amends those codes.
Westminster moves permits to the 2026 NEC effective August 1, 2026
The City states that permits need to comply with the 2026 National Electrical Code effective August 1, 2026. Electrical changes are identified with the bathroom scope, rather than hidden in a tile description.
Westminster uses paperless permitting through eTRAKiT
Westminster’s permitting is fully paperless through eTRAKiT. The permit application records the actual building and trade scope before interior work is concealed.
Westminster Building Division is the issuing body
Westminster Building Division is the local authority identified by the City. The project submits the actual building and trade scope through the City process.
Westminster publishes an inspection scheduling window
The City says inspections are primarily performed between 8am and 5pm Monday through Friday and may be scheduled up to five business days in advance. We incorporate that coordination into a permitted bathroom schedule.
Westminster shower and floor tile need a durable substrate plan
Waterproofing, mortar choice, flatness, crack isolation where appropriate, and movement joints are determined before tile is set. Expansive-soil effects are assessed from the actual substrate condition.
Tile Work Near Westminster
Apollo Construction plans bathroom floors, shower walls, tub surrounds, kitchen backsplashes, entry tile, laundry floors, fireplace surrounds, and transitions as construction assemblies. The visible tile is the last layer. The work begins with the existing substrate, moisture route, room use, tile size, layout, adjacent finishes, and the actual permit boundary. That makes a planning range more useful than a finish allowance that ignores the parts soon to be hidden.
Substrate and flatness
Tile needs a clean, stable, appropriately prepared surface. On a wood floor we look for stiffness, damaged framing, unsupported edges, fasteners, and height transitions. On a slab we look for cracks, moisture evidence, patch history, curl, and changes in elevation. The selected mortar, underlayment, membrane, or leveling product must be compatible with both the substrate and the tile format. Large-format tile makes flatness especially consequential because small departures can create lippage or weak coverage.
Movement, cracks, and transitions
Colorado’s expansive-soil conditions make movement planning practical, not decorative. A stable hairline surface crack is different from vertical displacement, recurring movement, water entry, or evidence of structural distress. We document what is visible and select crack isolation, uncoupling, soft joints, or perimeter movement accommodation only where the system and condition support it. A membrane cannot correct a wet slab, active movement, or insufficient floor structure. Doorways, dissimilar materials, cabinets, tubs, curbs, and fixed walls are considered before layout begins.
Shower waterproofing before finish work
Tile and grout are not the water-control layer in a shower. The shower relies on a compatible, continuous waterproof assembly with deliberate drain, corner, curb, niche, bench, and penetration details. The shower liner is water-tested before tile goes over it. We keep system components together rather than combining unrelated board, membrane, drain, mortar, grout, and sealant products. That disciplined sequence makes it easier to locate responsibility, preserve drainage, and avoid covering an unresolved detail.
Layout, setting, and finishing
Before setting tile, we establish focal lines, cut locations, drain position, joint pattern, trim, edge profile, and transitions to adjoining rooms. The layout is checked against doors, cabinets, plumbing trim, fixtures, and lighting so a small starting error is not repeated across the room. Mortar coverage, trowel selection, back-buttering when called for, cure time, grout choice, and flexible sealant at appropriate change-of-plane locations are selected for the material and environment. The aim is a durable assembly with a clean visual order, not simply a fast cover-up.
Planning ranges, changes, and closeout
Costs are discussed as planning ranges and estimates, never quotes, based on dimensions, tile and trim, demolition and disposal, access, layout complexity, substrate correction assumptions, waterproofing, fixtures, transitions, permit administration, and cleanup. If removal reveals damage, moisture, inadequate backing, or a different construction condition, we document the finding and explain its planning effect before proceeding. Closeout includes protection, a review of grout and sealant locations, cleanup within scope, and care guidance for the selected finishes.
For Westminster projects, field coordination also includes protection of adjacent finishes, staging, daily cleanup, access to the occupied home, fixture delivery, and the sequence of plumbing and electrical completion. Layout is approved before mortar is mixed, and any condition found after demolition is made visible before it affects the planned assembly or cost range.

Common Questions
Can new tile be installed over old tile?
Only after the existing finish, bond, height, flatness, moisture condition, and transitions are assessed. Removing the old layer often provides the clearer view of the substrate and makes it possible to correct hidden defects. The decision follows the actual assembly, not a blanket rule.
Why do tile floors crack?
Cracks can reflect substrate movement, insufficient stiffness, moisture, poor preparation, restraint at a perimeter, or a missing movement detail. We look at the crack pattern and building condition before recommending a repair or membrane.
What matters most in a shower tile installation?
The waterproof assembly, drainage, penetrations, substrate, and compatible system details matter before the selected tile and grout. Tile is installed only after those layers are properly prepared.
How are tile costs planned?
We combine measurements, tile selection, demolition, access, substrate and waterproofing assumptions, layout, trim, fixture coordination, permit administration, and cleanup into a planning range. It is refined as the site and scope become known.
Can Apollo Construction coordinate tile with a full bathroom remodel?
Yes. Coordinating fixtures, plumbing, electrical, ventilation, backing, waterproofing, tile, and transitions as one sequence helps prevent finish work from being opened again for an unresolved concealed decision.
