One of the most frequent questions I receive as a professional tiler in Perth is – “Can you tile over existing tiles?”
I truly understand why many homeowners would go this route. Besides saving a great deal of time, you can save money as well! Plus, you can avoid the mess.
In my several years as a tiler, I’ve handled hundreds of tiling projects in various places around Perth, from Joondalup to Fremantle. I would have to say that I have a lot of experience with overlay tiling and complete removal.
But let’s talk more on overlay tiling – does it really work? When isn’t it a good option? Let me explain a bit about this, what I’ve learned over the years and whether it works or not, and when it may or may not be a good option.
The Short Answer
Indeed, it’s quite reasonable to tile above current tiles. Still, the actual issue here is, “Should you go for it?”
Having handled a lot of tiling projects, I have come to see that although overlay tiling can be excellent in some circumstances, it is not necessarily the ideal choice for the long run, particularly for Perth homes.
Before I dig deeper on this, check out this feedback from one of our customers:
“Having Garry and the GIB crew tile my bathroom was an absolute pleasure. Right from the start, Garry has showed professionalism. I’ve witnessed his competence, consistency, and how he’s able to communicate openly. David (our tiler) cleaned every day and never left our house messy. He even fixed issues we were not sure how to address! I have interacted with several subcontractors, but they are the ones who gave the best service. I highly recommend them and for sure, I’ll be hiring them again. Perhaps, for my next bathroom renovation.” Ben Mc Namara
Now, going back to the topic.
Key Assessment Points
Before I actually decide to install tiles over existing ones, I would think things over and consider certain factors.
One is the integrity of the structure. So how do I evaluate this? Check the strength and condition of the flooring joist. Plus, weight-bearing capacity, subfloor stability, and current tile adhesion.
Then, I will evaluate the condition of the existing tiles. Crack, damage, and loose or hollow tiles. More importantly, I’ll gauge the levelness of the surface and the integrity of grout line.
Of course, the condition of the room would matter as well, which is why I make sure to check the door clearances, electrical outlets, height transitions, and even the plumbing.
More Real-World Experience
Let me share a client’s comment about our recent project:
“Absolutely amazing work!
Sadly, our builder ruined the tiling in our ensuite while building our new house. Given the very stressful situation, we chose to bring in the team of GIB Tiling, and my, what a difference that makes! Garry and his crew turned things entirely around.
We were in good hands from the time Garry entered. He immediately saw the problems we hadn’t seen and went on to work with our site supervisor to correct them before he started laying a tile. His professionalism, meticulous manner, and friendliness gave us peace of mind.
For our ensuite and shower, Garry’s crew performed a full-height tiling project, and the results are impressive! They worked fast and with amazing accuracy – never once compromised on quality. The final outcome is a bathroom with a look that we absolutely love,
Garry is not just a professional tiler, but someone who really cares. He made sure the work was done flawlessly and coordinated everything even under time limits. And when it comes to his team? They are equally seasoned (shout to Dave – such a legend!).
We are really appreciative as it is rare to encounter tradespeople who take this great passion in their work. If every trade was this great, building a house would really be enjoyable!
I couldn’t recommend GIB Tiling enough, regardless of the size or complexity of the job you need. Besides the competitive rates, they have an amazing crew and always maintains great quality of work. Garry, thank you! We will be referring you to every person we know!” Robin Trotter
The Critical Evaluation Process
It’s an all-encompassing analysis that I normally go through when deciding if an overlay is a good choice.
I analyse each and every tile very closely. A loose tile means disaster for the whole installation. Here’s how I do this:
First, I’ll pop in the sound test. Let’s see if there’s any odd noise that would give away points of weakness or looseness, sections with air gaps, or problems with lamination.
Second, I’ll go through checking the high and low spots of the floor, transition areas, and overall consistency.
Moisture Considerations
Given the climate of Perth, it’s crucial to consider moisture when it comes to tiling. What I found was that coastal properties usually have to deal with various challenges unlike those that live in inland suburbs. This issue was highlighted on a recent project I tackled.
Sarah Watson, one of our clients, has said this on her review:
“His crew did our bathroom, and it looks fantastic.”
This was a result of our extensive moisture testing, which we had done before we went ahead with the installation.
The process involved the following:
First of all, we assess moisture under the existing tiles. The assessment also extends to the area around the plumbing fixtures, perimeter walls, and the grout lines.
Doing so allows us to pinpoint actual sources of water, especially if there are plumbing leaks. The process will also include checking shower seepage, rising damp, and external water ingress.
Weight and Structural Considerations
Remember that when you install tiles over existing ones, that will significantly increase the floor load. Therefore, it’s important to also look into the weight and structural factors.
As for the weight, the existing tiles are usually about 20 to 25 kg for every square metre. The weight of the new ones will vary depending on the material. In addition, the weight of the adhesive, which is about 5 to 7 kg for every square metre will also be taken into consideration, as well as the combined load impact.
Technical Requirements for Successful Overlay
In the event overlay tiling is deemed desirable, technical requirements will first be assessed before proceeding further with the project.
A major step is to thoroughly prepare an existing surface, including deep cleaning of the whole area, stripping off sealers or waxes. Then, allow it to thoroughly dry.
Other things to look into are bonding aspects like the right primer application, adhesive selection, appropriate trowel notch size, and enough coverage patterns.
Height Considerations
After carrying out several tiling jobs, one of the things that I make sure to do early on is to properly manage the transition of heights. I have just accomplished a project that really tested my skills and ability.
Andy Wong, another client of ours has talked about us, saying:
“Garry is the man. He truly lived up to their great reviews and rating online. I came across him online. Indeed, he was able to deliver exactly what he promised!”
If you want to know more details about this, here’s what he was talking about:
“I’m a busy interstate investor; hence, I don’t often visit my property and just leave it to the agent. Arranging a tiler proved challenging because of availability and coordination among us – my agent, the tiler, and me. But I certainly do not want to overlook a leaky shower.
So, when I called Gary for help, he was quick to take on the job. There were some challenges, like scheduling access, but unlike other tilers who ghosted or refused the job, Garry and his team handled everything professionally. They have the skills and abilities to professionally tackle the project and have communicated well with us all throughout.”
This project has become a success thanks to our meticulous planning of the level changes among the rooms.
Common height adjustments include:
We will evaluate trimming choices, minimum clearance needs, threshold solutions, and transition strips for door clearances.
We will review plumbing extensions, toilet flange height, cabinet base adjustments, and electrical outlet extensions for fixture changes.
When Overlay Tiling Works Best
From what I have observed during those years working on various properties around Perth, overlay tiling will only work during the following situations:
The most ideal condition should be – perfectly sound existing tiles, levelled surfaces, dry surroundings, enough height allowances, and a solid flooring.
As for the most suitable locations, these are the living areas, hallways, low-traffic zones, and other dry areas.
When to Avoid Overlay Tiling
You must also be aware of when overlay tiling will not be appropriate.
Do not proceed with overlay tilling in scenarios like water-damaged areas, broken or loose tiles, uneven surfaces, structural issues, height-restricted places.
Long-Term Considerations
The decision to overlay tiles shouldn’t be based only on immediate factors.
I also discuss long-term considerations with my clients, such as future maintenance. It’s important for them to know that all tile installations will eventually require upkeep, and overlays can come with unique challenges.
Complicated repair procedures, restricted access to the original surface, issues identifying defects, and higher repair expenses are some of the possible drawbacks of overlay tiling.
This can also impact the property value. As what I observed from the property market of Perth, you must consider the following before going for overlay installations – buyer perceptions, home inspection impacts, resale value effects, and insurance implications.
Cost Comparison
Although initially more affordable, overlay tiling should not be taken at face value; rather, one should consider the whole financial picture:
Reduced labour fees, decreased demolition costs, no trash generation, and a faster project schedule are just a few of the benefits overlay tiling provides.
Conversely, total replacement calls for more labour, more initial investment, greater disposal expenses, and a longer project length.
Long-Term Financial Impact
Overlay tiling comes with potential future complications, limited repair options, higher maintenance costs, and the possibility of complete removal later.
As for full replacement, it offers better long-term durability, easier maintenance, more repair options, and a higher property value.
Professional Recommendations
Having worked in Perth’s tile business for years, this is my professional advice:
Should one decide to overlay, be sure to:
- Conduct professional assessment and that will include comprehensive surface testing, moisture evaluation, structural analysis, and a height feasibility study.
- Invest in high quality materials like high-grade primers, professional-grade adhesives, appropriate grout selection, and proper transition materials.
Although it’s not always the most ideal option, tiling over tiles may work in some circumstances. So how do you decide? First, carefully assess your space, budget, and long-term goals. Although overlay tiling saves money on initial costs, a complete removal and fresh installation usually proves to be more durable and valuable over time.
Remember, every tiling project is unique – what suits one house could not be perfect for you. Success depends on proper evaluation, planning, and execution. Consulting a specialist is therefore absolutely necessary since they can assess your needs and suggest the best course of action depending on certain factors.
As a professional tiler in Perth, my priority is delivering high-quality, long-lasting installations. Sometimes, that means advising against overlay tiling, even if it seems like the easier choice. Your home deserves the best solution, not just the quickest or cheapest one.
