The bathroom is where sealant quality is most visible and most critical. A poorly applied sealant joint in a wet area leads to water ingress, mould growth, and the kind of defects that generate repeat callbacks. Sycamore Sealants approaches every bathroom and wet room project with the precision required to get it right first time.
We work across all types of residential and commercial bathroom environments — from single domestic bathrooms to multi-storey hotel en-suite programmes. Our operatives are experienced with all tile substrates, shower enclosures, wet room systems, and bath panel configurations. The result is a clean, consistent joint that performs and looks professional for years.

Why Bathroom Sealant Matters
Water ingress behind tiles is one of the most expensive defects in residential construction. The cause is almost always a failed or incorrectly applied sealant joint. Using the right product in the right place — and applying it correctly with proper surface preparation — is the only reliable way to prevent it.
We specify mould-resistant, sanitary-grade silicone for all wet area applications. We don't cut corners on surface preparation. Joints are cleaned, degreased, and primed where necessary before sealant is applied.
Colour Options
We hold stock of a wide range of standard sealant colours including white, off-white, magnolia, cream, grey, anthracite, black, and clear. For colour-matched applications to specific tile ranges, we can source specialist products with a short lead time. We'll always confirm the colour against a tile sample before application on site.
Commercial Bathroom Programmes
For hotel en-suite programmes, student accommodation developments, and residential apartment blocks, we can scale resource to meet your programme. We've completed bathroom sealing programmes across developments of all sizes throughout Kent, Surrey, and Sussex.
Frequently Asked Questions
How long should bathroom sealant last?
With correct application and appropriate product selection, bathroom sealant should last 5–10 years in normal domestic use. Wet rooms and shower areas with daily use may need refreshing sooner. Using a mould-resistant formulation significantly extends the usable life of the joint.
When should I replace existing bathroom sealant?
You should replace sealant if you notice discolouration that doesn't clean off (usually black mould growth), cracking or shrinkage, peeling away from the substrate, or if water is getting behind tiles or into gaps. Don't leave it — water damage behind tiles is expensive to put right.
Can you re-seal just part of a bathroom?
Yes, though we'll always advise whether it makes sense to do the full bathroom at once. Partial re-sealing is possible, but colour matching to existing sealant can be difficult as it fades and discolours over time.
How long before I can use the shower or bath after sealing?
We recommend leaving sealant 24 hours before the first use. Most products are touch-dry within 1–2 hours, but the full cure takes longer — and getting water on the joint too soon compromises adhesion.
