DIY Tiling vs. Hiring a Pro: Real Risks and Real Costs
“While doing it yourself may seem like a cost-saver, it can actually cost more in the long run.”
Thinking of DIY Tiling? Here's What You Should Know First
Tiling might look easy on YouTube—but in reality, it’s a trade that demands precision, planning, and years of hands-on experience. As professional tilers, we often get called in to “fix” DIY jobs that went wrong. While doing it yourself may seem like a cost-saver, it can actually cost more in the long run.
In this article, we compare the real risks and costs of DIY tiling versus hiring a qualified tiler—so you can make the right decision for your home, your wallet, and your peace of mind.
🧱 The Appeal of DIY Tiling: Why Homeowners Try It
It’s easy to see why people are tempted to tile themselves:
You think you’ll save money on labour
You can work at your own pace
It feels like a satisfying weekend project
But DIY tiling often ends up being harder, slower, and more expensive than expected—especially when mistakes happen.
⚠️ Real Risks of DIY Tiling
1. Uneven Tiles and Lippage
Without proper tools, leveling systems, and experience, it’s easy to end up with lippage—tiles that sit at different heights. This not only looks bad but also creates trip hazards, especially with large-format tiles.
2. Poor Adhesion and Hollow Tiles
DIYers often use the wrong adhesive or apply it unevenly. Result? Tiles that sound hollow, crack, or come loose. Fixing this later means ripping everything up and starting again.
3. Grout Cracking or Discolouration
Inconsistent grout joints or rushing the grouting process can lead to cracked, stained, or patchy grout. It ruins the look of your space and weakens the whole installation.
4. Incorrect Waterproofing
One of the biggest risks. If you tile a bathroom or laundry without the correct membrane and banding, moisture can seep in, causing mold, rot, and thousands of dollars in hidden damage. This can also void your insurance.
5. Wasted Materials
DIYers often:
Order the wrong tile quantity
Break tiles during cutting
Mix grout inconsistently
Fail to prepare the substrate
The result? Wasted time and materials—and often more money spent replacing them.
