Michael Joint Sealer pty ltd
A professional builder in the sample calls Michael's caulking craftsmanship 'exceptional' — strong praise from someone who would know.
The standout detail for bathroom jobs is that he's earned endorsement from at least one professional builder in the sample, which carries more weight than a general homeowner compliment. The low sample coverage (under 9% of total reviews) means you're working with limited visibility, so it's worth asking him directly about his experience with your specific situation — shower resealing, expansion joints, or wet area re-caulking — before booking.

About Michael Joint Sealer pty ltd
Run by Michael (also known as Shahab), this is a solo-operator sealing and caulking specialist who focuses almost exclusively on residential silicone and joint work — not the broader waterproofing category that might imply large-scale membrane or drainage projects. The work customers describe is precise and hands-on: worn or mouldy shower silicone stripped out and replaced, bathroom sealing completed to a finish that at least one professional builder called 'exceptional craftsmanship.' Michael handles everything himself, which means the person quoting is the same person doing the job — useful for homeowners who want accountability rather than a crew of varying skill. His working style leans toward communication first: multiple reviews note he discusses the job before starting and responds quickly to initial enquiries. As a GST-registered company with nearly four years of trading, he sits in the bracket of a specialist sole trader who's formalised enough to invoice properly, rather than a cash-only handyman. Best suited to homeowners dealing with bathroom maintenance — silicone replacement, re-caulking, shower resealing — rather than major waterproofing renovations.
Best for: shower silicone replacement in residential bathrooms, re-caulking and joint sealing maintenance, and homeowners who want a sole operator they can deal with directly from quote to completion.

What types of sealing jobs does Michael typically handle?+
From the reviews available, Michael's core work is residential silicone and caulking — specifically stripping out worn or mouldy shower silicone and replacing it cleanly. Customers also mention bathroom sealing more broadly. This appears to be hands-on maintenance work rather than large-scale waterproofing projects like membrane installation or drainage. If your job involves something beyond silicone and joint sealing, it's worth confirming scope with him directly before booking.
How quickly does Michael respond and arrive for jobs?+
Multiple customers in the sample specifically mention fast response times and prompt arrival — one noted he 'responded very quickly' and 'arrived promptly.' This pattern appears across several reviews, suggesting reliability on scheduling is a genuine strength rather than a one-off. That said, availability will depend on his current workload, so contact him early if you have a fixed timeline.
What do customers say about Michael's pricing?+
Pricing comes up positively in several of the sampled reviews, with customers using phrases like 'very reasonable and fair price' and 'reasonable quote.' No reviews in the sample flagged pricing as a concern. Keep in mind this is based on a small sample of 5 reviews, and silicone or caulking jobs vary in scope — get a quote for your specific job rather than assuming a flat rate.
Is Michael a sole operator or does he run a team?+
All reviews name Michael (also referred to as Shahab) personally, and the business is structured as a small company rather than a multi-crew operation. This means you're likely getting the owner on-site for your job, which customers seem to value — the builder who reviewed him specifically praised his individual craftsmanship. Confirm with Michael directly if you have a large or time-sensitive job that might require additional hands.
Does Michael operate around Guildford and the surrounding suburbs?+
The business is based in Guildford, NSW. Reviews don't specify exact service radius, so it's not possible to confirm from available data which surrounding suburbs he covers regularly. It's worth asking him directly when you make contact, particularly if you're outside the immediate western Sydney area.
