Hiring a professional for tile installation is a smart investment, but the process can feel mysterious if you have never been through it before. Knowing what to expect at each stage helps you prepare your home, set realistic timelines, and avoid unnecessary stress. Here is a clear walkthrough of what happens from the first site visit to the final cleanup.
Step 1: The Site Assessment
Before any work begins, a qualified installer will visit your home to evaluate the space. This is not just about measuring square footage. The installer checks the condition of your existing substrate, whether it is concrete slab, plywood subfloor, or an existing tile surface. They look for cracks, moisture issues, levelness, and structural integrity.
This visit is also when layout decisions are made. Which direction should the tile run? Where do cuts fall? How will the tile meet doorways and transitions? A good installer thinks through these details before the first tile is ever set.
Step 2: Surface Preparation
Surface prep is the most important step in any tile installation and the one most DIYers underestimate. Depending on your situation, this may involve removing existing flooring, grinding down high spots in the concrete, applying a self-leveling compound to correct dips, or installing cement backer board over plywood subfloors.
In South Florida, where most homes are built on concrete slabs, the installer will also test moisture levels. Excessive moisture vapor emission from the slab can prevent thinset mortar from bonding properly, leading to loose tiles down the road. If moisture levels are high, a mitigation membrane is applied first.
Step 3: Layout and Dry Fit
Before any adhesive is mixed, experienced installers dry-lay a section of tile to verify the layout. This step reveals whether the planned pattern works visually and practically. It catches problems like ending up with a sliver of tile at a doorway or an awkward cut along a visible wall. Adjustments are much easier to make before anything is glued down.
Step 4: Setting the Tile
Tile is set using thinset mortar applied with a notched trowel. The size of the trowel notch depends on the tile size. Larger tiles require larger notches to ensure full adhesive coverage on the back of each piece. For tiles 15 inches and larger, most professionals use a technique called back-buttering, where mortar is applied to both the substrate and the back of the tile to eliminate air pockets.
Spacers or leveling clips are placed between tiles to maintain consistent grout joints. Leveling systems are especially important for large-format tiles where even a slight lippage between tiles becomes visible and feels uneven underfoot.
Step 5: Grouting
After the thinset has cured for at least 24 hours, the spacers are removed and grout is applied. The installer works grout into the joints at an angle using a rubber float, then wipes away excess with a damp sponge. Grout color is a design decision worth thinking about carefully. A grout that matches the tile creates a seamless look, while a contrasting grout highlights the tile pattern.
For areas exposed to water like showers and bathroom floors, an epoxy grout may be recommended. It is more difficult to work with but resists staining and mold far better than standard cement grout.
Step 6: Curing and Cleanup
Grout needs 24 to 72 hours to fully cure before the floor can handle normal foot traffic. During this time, avoid walking on the tile and keep the area dry. Once cured, the installer does a final cleaning to remove any grout haze from the tile surface. Grout sealer is then applied if you are using cement-based grout.
How Long Does Tile Installation Take and What Should You Prepare?
A typical bathroom floor takes one to two days for installation plus curing time. A full home floor project of 1,000 to 2,000 square feet usually takes three to five working days, not counting demolition and prep work which can add one to two more days.
Before the crew arrives, clear the rooms of furniture, rugs, and personal items. If the project involves your kitchen, plan alternative cooking arrangements. If the work is in a bathroom, make sure you have access to another one. The team at AP STONE INC. always provides a clear timeline and preparation checklist before starting any project, so there are no surprises along the way.

What Does a Professional Tile Installation Actually Include?
Many homeowners are surprised to learn how much of a tile installation happens before the first tile is set. In a properly executed project, surface preparation alone accounts for 30–40% of total labor time. This is the foundation that determines whether your floor remains flat, crack-free, and bonded five years from now or starts showing problems within 18 months.
Here is the complete breakdown of what a professional installation includes — and what separates a qualified contractor from someone who will create problems you will pay to fix later.
| Phase | What It Involves | Time | Why It Matters |
|---|---|---|---|
| Site Assessment | Measure, moisture test, inspect subfloor | 1–2 hrs | Identifies problems before they become your problems |
| Demolition | Remove existing tile/flooring, dispose | 4–8 hrs | Clean removal prevents substrate damage |
| Subfloor Prep | Grind highs, fill lows, apply self-leveler | 4–16 hrs | Flatness standard: max 1/8" variation per 10 ft |
| Layout | Establish control lines, dry-fit | 1–3 hrs | Prevents awkward cuts at visible edges |
| Setting | Mortar application, tile placement, leveling | 1–3 days | 95%+ mortar coverage required (TCNA standard) |
| Cure | 24–48 hr mortar cure before grouting | 1–2 days | Skipping this step causes cracked grout |
| Grouting | Mix, apply, clean, haze removal | 4–8 hrs | Color consistency and joint width precision |
| Sealing | Grout and stone sealer application | 1–2 hrs | Protects against moisture and staining |
Miami-Specific Considerations During Installation
South Florida presents specific challenges that affect how installations are planned and executed. Concrete slab moisture vapor emission is one of the most underappreciated factors. Miami's high water table causes moisture to push up through concrete floors, and if that moisture cannot escape after tile is installed, it traps under the adhesive and causes delamination. For any direct-to-slab installation, we perform a calcium chloride moisture test per ASTM F1869 before committing to an adhesive system.
Condo buildings in Miami-Dade require additional coordination: HOA approval, building permit, freight elevator scheduling, and noise restrictions (typically 9 am–5 pm weekdays). We handle all of this as part of our project planning — it adds 1–2 weeks to the pre-construction phase but eliminates surprises during the job.
Miami's temperature also affects mortar open time. On hot days (which is most of the year), mortar skinning occurs faster. We adjust our mix consistency and work in smaller sections during summer months to maintain the mortar's bond window.
