Frequently Asked Questions
What is silicone caulking, and why do I need it?
Silicone caulking seals gaps and joints in various surfaces. It protects your home or building from moisture, air leaks, and dust. It also allows for movement between surfaces, preventing cracks and damage.
What’s the difference between silicone and polyurethane sealant?
Silicone is more flexible and ideal for indoor wet areas. Polyurethane is stronger and perfect for outdoor or structural joints. We use both based on your project's needs.
Do you work on residential and commercial projects?
Yes. We seal everything from small bathroom gaps in homes to large expansion joints in commercial buildings and civil infrastructure.
How long does joint sealing last?
With professional application and quality materials, silicone or polyurethane sealing can last 10+ years, longer with regular maintenance.
Do you offer fire-rated caulking?
Absolutely. We apply specialised fire-rated sealants around electrical boxes, service penetrations, and passive fire barriers.
