How to Remove Old Floor Tiles Without Destroying Your Subfloor (Tools You Can Hire)
When you’re renovating a bathroom, kitchen, or outdoor area in Perth, removing old tiles is often the first—and messiest—step. Done right, it sets you up for a smooth install. Done wrong, and you risk damaging the subfloor, adding time, cost, and frustration to your project.
The challenge? Most DIYers and even tradies underestimate how tough tile removal can be—especially when dealing with strong adhesives, old mortar beds, or fragile concrete slabs underneath.
In this guide by Quinns Rocks Tool Hire, we’ll break down how to remove floor tiles safely, protect your subfloor, and choose the right tools for the job.
Why Subfloor Protection Matters
Before you even pick up a tool, it’s important to understand what’s at stake.
Your subfloor—whether it’s concrete, timber, or screed—is the foundation for your new flooring. Damage it, and you could be dealing with:
- Uneven surfaces that affect new tile installation
- Cracks in concrete slabs
- Weak spots in timber flooring
- Extra levelling costs before re-tiling
👉 The goal isn’t just removing tiles—it’s removing them cleanly and efficiently without unnecessary damage.
What Makes Tile Removal Difficult?
Not all tile jobs are created equal. The difficulty depends on:
- Adhesive type – Older mortar beds are tougher than modern adhesives
- Tile material – Porcelain and stone are harder to break than ceramic
- Subfloor type – Concrete is more forgiving than timber
- Age of installation – Older tiles tend to bond more aggressively
💡 Perth context: Many older homes across suburbs like Joondalup, Clarkson, and Wanneroo have tiles laid with thick mortar beds—these require heavier-duty tools compared to newer adhesive-based installs.

Best Tools to Remove Floor Tiles (Without Damaging the Subfloor)
Choosing the right tool is everything. Here’s what works—and when to use it.
1. Electric Jackhammer (Tile Removal Hammer)
An electric jackhammer (or demolition hammer) is the most efficient tool for removing floor tiles, especially across large areas.
It uses a wide chisel blade to get underneath tiles and lift them without digging too deep into the subfloor.
Best for:
- Large tiled areas (kitchens, living rooms, patios)
- Tiles fixed to concrete slabs
- Thick adhesive or mortar beds
👉 Pro tip: Keep the chisel at a shallow angle to avoid gouging the concrete underneath.
2. Floor Scraper (Manual or Long-Handle)
Once tiles are removed, you’ll still need to deal with leftover adhesive—and that’s where a floor scraper comes in.
Best for:
- Removing glue, adhesive, or thinset residue
- Finishing work after jackhammer use
- Smaller or delicate areas
👉 This is essential if you want a smooth surface ready for re-tiling.
3. Angle Grinder with Diamond Cup Wheel
For stubborn adhesive that won’t budge, an angle grinder with a diamond cup wheel is your go-to.
It grinds down remaining material to leave a flat, level finish.
Best for:
- Hard adhesive residue
- Surface levelling before new tiles
- Preparing concrete for coatings or epoxy
👉 Important: This creates dust—always use proper PPE and dust control.

4. Multi-Tool or Small Chisel (Detail Work)
For tight corners and edges where larger tools can’t reach, a multi-tool or small chisel gives you precision.
Best for:
- Edges near walls
- Around fixtures or cabinets
- Small repair areas
Step-by-Step: How to Remove Tiles Safely
Follow this proven method to minimise subfloor damage:
1. Start with a Test Area
Pick a loose or cracked tile and see how easily it lifts. This tells you what you’re dealing with.
2. Break and Lift Tiles
Use a jackhammer or chisel to break tiles and slide underneath them—not straight down.
3. Work in Sections
Don’t rush. Remove tiles in manageable areas to maintain control.
4. Remove Adhesive
Switch to a floor scraper or grinder to clean the surface.
5. Inspect the Subfloor
Check for cracks, gouges, or uneven spots before installing new flooring.

Common Mistakes That Damage Subfloors
Avoid these, and you’ll save yourself major headaches:
- Using the wrong angle with a jackhammer (causes gouging)
- Skipping adhesive removal, leading to uneven new tiles
- Rushing the job, which increases breakage and damage
- Using heavy tools on timber subfloors without control
👉 If you’re unsure, it’s always worth asking your local hire team for advice before starting.
When Should You Hire Tile Removal Tools?
Hiring is the smarter choice when:
- You’re removing tiles from medium to large areas
- Adhesive is thick or stubborn
- You want a professional finish without buying expensive tools
- It’s a one-off renovation job
💡 Example Perth projects:
- Bathroom renovation in Quinns Rocks
- Kitchen tile removal in Clarkson
- Outdoor patio upgrade in Butler
- Laundry renovation in Joondalup
Why Hire Instead of Buying?
For most Perth DIYers and tradies, hiring tile removal tools makes more sense:
- No upfront investment – Jackhammers and grinders can cost hundreds to thousands
- Access to the right tool – Use heavy-duty gear only when needed
- No maintenance or storage issues
- Expert advice included
👉 Quinns Rocks Tool Hire offers reliable, well-maintained equipment ready for your next renovation project.
