Local considerations we plan for.
- Home styles: victorian workers' cottages and edwardian terraces dominate the streetscape — informs substrate choice and layout options.
- Preferred finishes: local requests skew toward handmade moroccan zellige and terrazzo slabs.
- Site logistics: Access is the single hardest thing about Brunswick jobs — many terraces have no rear lane, no driveway, and street parking is metered. We plan material deliveries on off-peak days and use protective floor coverings from footpath to bathroom door.
Everything under one contract.
Frequently asked.
Do you cover our part of Brunswick?
Yes. We service all of Brunswick (3056) and the surrounding suburbs — Coburg, Pascoe Vale. Free on-site measure across the entire area.
Which bathroom waterproofing style suits Brunswick homes best?
Given the local mix of victorian workers' cottages and edwardian terraces, we most often recommend handmade moroccan zellige, paired with bath removed for architectural walk-in shower. Every recommendation is confirmed against your specific floor plan during the design session.
Do we need to remove tiles for you to waterproof?
Yes — proper waterproofing sits behind the tile bed. Any 'topical' membrane applied over existing tiles is a temporary bandaid, not a compliant fix.
Will insurance accept your certificate?
Yes. Every certificate is issued in the applicator's name with photographic evidence attached, which is what insurers require for future claims.
