FAQ: What is remedial waterproofing?

Remedial waterproofing, which Foreshore Projects & Maintenance carries out on the Lower North Shore, repairs or replaces a waterproof membrane that has failed, usually after a leak shows up. Tim does this work on balconies, roof terraces, planter boxes and wet areas under his waterproofing licence (189495C).

The job starts with finding the source of the leak, since water often shows up away from where it gets in. Tim then scopes the repair and any membrane or sealant system required, and quotes it in writing. In older buildings the leak can sit behind a second problem, so he'll tell you at the inspection whether a repair is likely to settle the issue or whether it needs staged investigation.

FAQ: Does Foreshore hold a waterproofing licence?

Yes, Foreshore Projects & Maintenance holds waterproofing licence 189495C through its owner, Tim Carter, and carries out waterproofing assessment and repair under it. If a strata committee, agent or lease requires proof, ask when you request a quote and Tim will send through the details. You can also check the licence number through NSW Fair Trading.

It's worth confirming what the licence covers for your particular job, so raise that at the quoting stage. For work outside waterproofing, such as electrical or plumbing, Tim will recommend a licensed specialist. Waterproofing products often carry manufacturer warranties, and Tim sets out what applies to the product proposed for your job in the quote.

FAQ: How can I tell if a commercial wet area or balcony is leaking?

Foreshore Projects & Maintenance looks for the following signs when it inspects a commercial wet area or balcony for leaks:

  • Staining or bubbling paint on walls and ceilings
  • Damp patches or a musty smell
  • Lifting or cracked tiles
  • Mould, or stained ceilings in the space below

Tim confirms the source of the leak, which can sit away from where the water appears, before quoting a repair. Moisture can travel along slabs and walls, which is why diagnosis comes before any repair. Photos and a note of when the problem started help Tim plan the inspection. Tell him whether the problem is new or has returned after an earlier repair, because that changes where he looks first.

FAQ: Can Foreshore repair a leaking balcony in a strata building?

Yes, Foreshore Projects & Maintenance diagnoses and repairs leaking balconies and terraces in strata buildings on the Lower North Shore. Tim will confirm whether the leak comes from common property or from inside one lot, since that usually decides who arranges and pays for the repair. In NSW, the owners corporation is generally responsible for common property, and your strata manager or insurer can confirm your situation.

Once the source is clear, he provides a written quote covering the repair and any membrane or sealant system. The strata side of the work, including committee approval and resident notice, is covered on the strata maintenance page. This is general information, not legal advice.

FAQ: How is a commercial leak repair quoted?

Foreshore Projects & Maintenance quotes commercial leak repairs in writing after an inspection. Describe where the leak is showing up and how long it's been happening, and Tim will inspect the area to find the source before scoping the work. The quote covers the repair and any membrane or sealant system required, plus a condition report where one is needed.

Costs depend on the area, access and materials, so there's no fixed price list. A quote usually follows within one to three business days of receiving your details. Where a leak is hard to trace, Tim says so plainly in the quote and won't promise a result he can't stand behind. Warranty terms depend on the product used, and he confirms them for your job in writing.
