Remedial Group
Billy named personally in every review for steering complex jobs across the finish line on time.
That said, based on this small sample of recent reviews, the standout pattern is unusually consistent: every customer mentions Billy by name as the person keeping them informed, and two reviewers specifically flag that timelines were honoured on what sound like big jobs. For a homeowner dealing with waterproofing or roofing remediation — work that often drags and rarely ends clean — that track record on communication and scheduling is the thing worth pressing him on directly when you get a quote.

About Remedial Group
Billy leads Remedial Group's waterproofing and roofing work out of Gymea Bay, and from what customers describe, he's the kind of tradesperson who stays personally involved from quote to completion — not someone who sends a crew and disappears. Reviews highlight him specifically for keeping homeowners in the loop throughout what sounds like substantial, multi-stage jobs, suggesting this isn't a team that cuts corners on communication when complexity ramps up. The business operates as a registered company with GST registration, which matters for homeowners wanting formal invoicing or looking to claim expenses on investment properties. Google also lists roofing contractor as a primary category alongside waterproofing, which implies Remedial Group can address the intersection of both trades — the kind of overlap that often trips up projects when two separate contractors need to coordinate. Based on the jobs reviewed, their work skews toward larger-scale residential remediation rather than quick patch-ups, making them worth considering if you've been putting off a problem because it felt too complicated to manage.
Best for: large-scale residential waterproofing and roofing remediation, homeowners who want a single accountable contact throughout the job, and investment property owners needing formal tax invoicing.

Who actually turns up on site for Remedial Group jobs?+
Based on all three reviews we analysed, Billy is personally present and managing communication throughout each job. Customers don't describe a scenario where they dealt with a site foreman while Billy stayed in the background — his name comes up as the direct point of contact. That said, with only a small review sample to draw from, it's worth confirming with him directly whether he'll be on-site for your specific job or managing it from a distance.
How does Remedial Group handle project timelines?+
Timeline reliability is the most consistent theme across the reviews we saw. Two customers specifically mention that Billy kept to the promised schedule — one on what they described as a big job. Waterproofing and remedial roofing projects are notoriously prone to scope creep and delays, so asking Billy upfront for a written timeline and milestone check-ins seems worth doing based on what reviewers valued most.
Is Remedial Group set up for investment property or strata work?+
Yes — the business is GST registered and operates as a company, which means they can issue formal tax invoices suitable for investment property owners or strata managers needing documentation for claims or body corporate records. Reviews don't specifically mention strata jobs, so if your project involves a strata scheme or owners corporation, confirm with Billy that he's worked in that context before.
What size jobs does Remedial Group typically take on?+
The jobs described in reviews sound substantial — multiple customers use phrases like 'big job' and note the work required ongoing updates across multiple stages. This suggests Remedial Group is comfortable with larger-scale remediation projects rather than minor patch repairs. If you have a smaller, straightforward job, it's still worth reaching out, but set expectations that their experience appears weighted toward more involved scopes of work.
How recent is the feedback available for Remedial Group?+
The reviews we were able to analyse date from late 2020 to early 2021, which means there's a gap between the most recent customer feedback and today. With only 5 total Google reviews on record, there isn't a lot of recent activity to draw conclusions from. We'd recommend asking Billy directly for references from jobs completed in the last 12 months so you can get a more current picture of how the team is operating.
