Outdoor Wall Waterproofing+Fixing ground gutter

Adam is a fantastic communicator and incredible efficient. He is punctual, true to his word and an expert at what he does. He’s also very trustworthy and honest. I had major leaking issues in my shower which affected the adjoining wall and he pulled back the tiles, removed all cement and waterproofed the area, added original tiles and grouted the area as well as waterproofing the walls of the shower with spray.

Hello - I am in desperate need of an experienced team to address moisture issues in one of my bathroom walls (not entire bathroom). There are no major structural damages, nor relocation of plumbing is required, however I need help to address: * remediate waterproofing the moisture on one side of the bathroom wall (address rotten studs, mould remediation) to ensure it is compliant with NSW waterproofing standards * replace toilet x 2 (in this bathroom and the spare) * replace vanity * cover and close skylight (pictures show damage by branch on roof) * tile patching / partial retiling (only on affected wall, not entire bathroom) * minor painting/plaster repair The house is empty atm so I am flexible for you to spend 1-2 weeks working on to get all this remediated. My budget is limited so hoping this quote can include: * toilet seat replacements x 2 * vanity cabinet * tiles * skylight cover and roofing * waterproofing *silicone and paints * any other equipment you require Otherwise, happy to discuss and work something out. Taking into consideration AirTasker 20% fee, offer is about ~$5k.

Glen Alpine NSW, Australia

Hi, I’m looking for an experienced bathroom renovator / tiler / waterproofing specialist to fix a shower leak issue. 🔍 Issue description: • Double-storey house • Bathroom upstairs • Water leaks to the ceiling of the downstairs bathroom • Leak happens only after longer showers • Water appears around the ceiling heat lamp/exhaust fan below 👉 This is likely a waterproofing failure in the shower area 🎯 Scope of work: I need someone to: 1. Inspect and confirm the cause • Confirm waterproofing failure vs pipe issue • Identify leak source (shower floor / wall junction / drain area) 2. Provide repair solution Please quote for BOTH options: Option A (preferred): • Remove tiles in shower area • Re-do waterproofing membrane • Re-tile affected area Option B (if possible): • Minor repair (regrouting / resealing) – only if suitable ⚠️ Important requirements: • Must have experience in shower waterproofing • Must follow Australian waterproofing standards • Proper membrane installation required (not just silicone fix) 📸 Please include: • Photos of previous similar jobs • Estimated cost for each option • Timeline 💰 Budget guide: Open to quotes, but looking for a proper long-term fix, not temporary patching.
