New build mastic in Five Ash Down
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you’re dealing with skirting joints opening in the first winter and second-fix sealing on new plots, we can help.
Work in a small place like Five Ash Down just needs the journey and access planning, and the work itself is the same as on any site.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Five Ash Down can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Surface 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.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
When to call us in Five Ash Down
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
The problems people usually mention when they call include:
- Plot mastic for developers ahead of handover
- Shower seals failing in the first year or two
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
For new homes near Buxted station, it’s worth checking the sealant early, while snags are still fresh.

Will you come out to Five Ash Down?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Five Ash Down in your area for new build mastic?
Yes, Five Ash Down is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
What colour sealant will you use?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before we start.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
