What Our Clients Say
FAQs
Frequently Asked Questions
How do I know if my bathroom silicone has actually failed or just needs a good clean?
If it’s lifting at the edges, cracking through, or letting water behind the tiles, it has failed and needs to be replaced cleaning won’t fix it.
Will resealing my shower stop the leak permanently?
Yes, if the joint itself is the issue — but if the waterproofing membrane underneath is damaged, that needs a proper repair first.
Can you match the new silicone colour to my existing tiles or grout in Thornbury, VIC?
We carry a range of standard colours and will show you options before we start so there are no surprises on the day
How long before I can use the shower again after you've resealed it?
Most silicone needs 24 hours to cure fully before the area gets wet again — we’ll confirm the exact timeframe based on the product used.
Do you carry out exterior window caulking services in Thornbury on multi-storey buildings?
Yes, we have rope access capability for buildings where standard ladders won’t reach, so no job is too high
What causes window seals to fail faster on Thornbury properties near the tram route?
Constant low-level vibration from trams gradually loosens rigid silicone seals properties near the High Street route benefit from flexible polyurethane sealants.

Yes, we schedule weekend appointments for clients who can’t be home during the week, just let us know when you call.
Do you handle window caulking repair on both heritage timber and modern aluminium frames?

Yes, all our work is backed by a workmanship warranty, and the materials we use are rated for five to ten years in residential applications.
Is caulking needed around roof penetrations like skylights and aerials in Thornbury?
Yes, vents, skylights, and aerials are among the most common sources of water ingress and are well within our exterior sealing scope.

How do I get the most out of my resealing shower silicone long term?
Keep the area ventilated after showers, clean with non-abrasive products, and have it checked every few years to catch any early wear.
