Why I Waterproof My Own Jobs as a Tiler: Here's the Proof.
As a tiler with years of experience, I’ve always believed in the importance of controlling every aspect of a project from start to finish—especially when it comes to waterproofing. In this blog, I want to highlight why I choose to waterproof my own tiling jobs—and why, as a customer, you should consider the long-term risks of leaving waterproofing to other trades. Poor workmanship in waterproofing is one of the most costly mistakes a homeowner can make, and it can cost you double in the long run—both financially and in terms of stress and hassle.
Let me explain. When a tiler arrives on site to complete the final tiling work, they expect a solid, well-prepped, and properly sealed foundation from the waterproofing. But when another tradie, who may not have the same care or attention to detail, rushes the waterproofing job—often skipping essential steps like cleaning, priming, or allowing proper curing—it puts the entire tiling job at risk. I recently encountered a project where this exact scenario unfolded. The waterproofer simply applied the membrane right over bare soil—no cleaning, no priming—just a shortcut to get it done quickly. On top, it looked fine at first, and even though I checked, it seemed solid. But when I looked closer, especially on the sides, the waterproofing peeled off like a banana—completely compromised. And this, I want you to understand, is why I always take responsibility for waterproofing on my own jobs.
When the tiling tradesman arrives after a substandard waterproofing application, the problem is that it often forces the customer to pay twice. First, they pay for the initial job, only to have it fail, and then they pay again to rip out and redo the entire tiling and waterproofing process. In short, a small shortcut on a waterproofing job can cost you double—sometimes more—when the job collapses later. That’s why I, as a tiler, choose to take full ownership of the waterproofing stage in my projects. I know exactly what prep work has been done from the very first layer of membrane to the final top coat. By doing so, I can ensure that my tiling is installed on a rock-solid, long-lasting foundation.
Now, I’m not saying that all tilers are bad at waterproofing. There are some fantastic waterproofers out there—true professionals who follow the code, take every precaution, and deliver flawless work. But this is exactly why you have to be careful with who you hire. Whether a tiler or a waterproofer charges you a bargain rate or a premium price, the key is that they must adhere to the standards and take all the necessary steps. This isn’t about cutting corners or rushing for a quick win; it’s about ensuring that the work lasts forever—beyond the standard warranty period, beyond five or ten years—so it endures as long as you live in the house, or until the house itself is gone.
I believe that a tiler who takes ownership of waterproofing is a tiler who is accountable. From the initial inspection to every layer of application, I know that my work is done to maximum standards. I follow the codes, I take the time to prep the surfaces, and I treat each job as if it were my own home. It’s not about being the cheapest; it’s about being the most reliable. Because at the end of the day, the real cost isn’t just the price of the initial job—it’s the peace of mind, the longevity of your home, and the avoidance of massive future costs. Every customer I work with deserves a job that doesn’t just meet the minimum standards but surpasses them. I believe every tiling project should be a long-term investment. And that means not only using the best materials but also ensuring that the prep, the process, and the execution are done by someone who fully understands the stakes. So, if you’re about to embark on a tiling project, my advice is simple: don’t just look at the price. Look at the commitment to quality. Choose a tiler who takes full ownership of the waterproofing as part of the whole tiling process. And remember, a good tiler won’t just give you a beautiful surface; they’ll give you a waterproofing job that stands the test of time—no shortcuts, just solid, lasting quality. Because at the end of the day, your home deserves nothing less.
