How we handle new build mastic in Jockey End
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you’re dealing with frame joints opening as the plaster dries and untidy sealant flagged on a snagging list, we can help.
Around Jockey End, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Whatever the size of the job, it’s backed by our 12-month guarantee in Jockey End and across Hertfordshire.

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.

What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Where a wall is exposed, as many are in small places like Jockey End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Advice
Common problems we fix in Jockey End
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
These are the problems we’re asked about most:
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Berkhamsted station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- What the quote includes, VAT included or not
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
- How much experience the applicator has
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
