Grout and About Perth
The tradesperson Perth customers call back when their builder's tiler couldn't fix the problem.
For homeowners frustrated by builders or tilers who've failed to fix persistent grout and water penetration issues, he's specifically mentioned as the person who finally got it right. The business is GST-registered and has been active for over a decade, which adds some structural confidence for anyone commissioning multi-area work. When getting a quote, it's worth confirming his current availability — sole-trader operations with strong word-of-mouth tend to book out.

About Grout and About Perth
Mariano (also called Mario by customers) runs this sole-trader operation himself, occasionally working alongside his assistant Andrea on larger jobs like multi-balcony waterproofing and bathroom regrouting. The business zeroes in on tiling remediation — specifically regrouting showers, bathrooms, kitchens, balconies, porches, and alfresco areas — rather than general waterproofing contracting, which makes it a genuinely specialist choice for homeowners dealing with failing or ageing grout rather than a full waterproofing membrane job. Reviews mention him succeeding where high-end builders and their nominated tilers couldn't resolve persistent shower grout issues, which speaks to a diagnostic depth beyond standard tile-laying. His working method draws repeated praise for meticulous communication throughout a job, not just at the quote stage — he flags what he's doing and why, and manages the dust and cleanup that regrouting inevitably produces. The business suits homeowners who've already had a go at cheaper fixes and need a craftsman-level result, whether that's a single ensuite or three outdoor entertaining areas tackled in sequence.
Best for: regrouting showers and bathrooms after a builder's fix has failed, tackling multiple outdoor tiled areas with water penetration issues, and homeowners who want a craftsman-level finish rather than a patch job.

What types of jobs does Grout and About Perth specialise in?+
The business focuses specifically on regrouting and tiling remediation rather than broad waterproofing contracting. Jobs mentioned across reviews include showers, ensuites, kitchen splashbacks, and outdoor areas like balconies, alfresco spaces, and porches. Mariano is also noted for tackling water penetration issues in outdoor tiled areas, not just cosmetic regrout work. If you have failing grout across multiple rooms or outdoor spaces, this appears to be a core strength of the business.
What do customers say about Mario's pricing?+
Pricing is described as competitive in multiple reviews, with one customer noting he returned for a second bathroom specifically because the pricing and quality aligned well. Reviews don't cite specific dollar figures, so you'll need a quote for your job. Given the specialist nature of the work, it's worth getting a couple of comparisons — though reviews suggest the finish quality justifies the cost.
Does Mariano work alone or does he bring a team?+
He primarily operates as a sole trader, but at least one review — covering three large balconies and an ensuite — mentions him working with an assistant named Andrea. For larger multi-area jobs, it's worth confirming at the quote stage whether an assistant will be on site, as this can affect timeline and scheduling.
Can Grout and About Perth fix regrouting issues a previous tiler couldn't resolve?+
This comes up directly in the reviews — one customer had multiple failed attempts by their high-end builder's nominated tiler before engaging Mariano, who resolved the issue. Another noted they'd be returning later in the year for outdoor water penetration repairs after being satisfied with the bathroom work. Reviews don't cover every scenario, so describe your specific situation when requesting a quote so he can assess whether it's within scope.
What areas does Grout and About Perth service?+
The business is based in Edgewater, WA. Reviews don't mention geographic boundaries explicitly, so it's unclear exactly how far out he travels. Given he's a sole trader operating across metro Perth, it's worth confirming your suburb is within his service area when you make contact, particularly if you're in the outer northern or southern suburbs.
