How we handle new build mastic in Homerton
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. If you’re dealing with messy sealant that spoils new finishes and sealant that never bonded to the surface, we can help.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

How the job changes by surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one.

Why act early in Homerton
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can call 0345 464 0079 or send us an email with a few pictures and we will tell you. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Homerton.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid scourers and strong chemicals on sealant
- Put sealant faults on your snagging list early
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
Signs you need new build mastic in Homerton
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
If you can see any of these, it’s time to have the joints looked at:
- Beads laid onto grit and dust from the build
- Frame joints opening as the plaster dries
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
If you’ve bought a new home near Homerton station, the sealant around baths, showers and frames is worth checking in the first year or two.
