Common call-outs are for sealant work across a run of new homes and leaking shower tray seals in a new home, across windows & doors, skirting & floors and kitchens.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Report sealant problems to your builder during the snagging period
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
Fairseat questions
Can you do new build mastic in Fairseat?
Yes, Fairseat is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
I let a flat near Borough Green & Wrotham station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
- Damaged fittings that need replacing
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

What we are called out for in Fairseat
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Look out for any of the following:
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
Around Fairseat, as everywhere, new build mastic is only as good as the preparation behind it.

Different surfaces, different methods
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
