New build mastic in Fairwarp, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you have new-build shower sealant that has already split and sealant applied over dusty or wet surfaces, we can put it right, on show homes, plot handovers and bathrooms & en suites alike.
Older homes in small places like Fairwarp often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep pictures and emails about snagging items
- Don’t wait for the house to settle if water is getting through
- Use the extractor fan every time you shower
- Keep water off fresh sealant until it has cured
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Common problems we fix in Fairwarp
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
If you can see any of these, it’s time to have the joints looked at:
- Sealant applied over dusty or wet surfaces
- Gaps behind new kitchen upstands
- Cracked sealant around new window and door frames
- Sealant work across a run of new homes
For new homes near Buxted station, it’s worth checking the sealant early, while snags are still fresh.

Questions from Fairwarp
Can you help a landlord with a rental near Buxted station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you cover Fairwarp for new build mastic?
Yes, Fairwarp is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with photos if you can, and we’ll quote. We will flag anything that needs another trade.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope and we will quote.
Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. Around Fairwarp, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
