Advice
About our new build mastic in Hatfield Heath
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on windows & doors, bathrooms & en suites and kitchens, and common reasons people get in touch are smeared, uneven beads picked up at snagging and joints pulling apart as timber shrinks.
For a small place like Hatfield Heath, the journey and access are planned in advance, and the work itself is the same as on any site.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Common problems we fix in Hatfield Heath
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry.
The problems people generally mention when they call include:
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
- Kitchen sealant that has pulled off the wall
- Gaps between new skirting and floors
For new homes near Sawbridgeworth station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in and baths are filled before sealing.
