Advice
New build mastic in Kingsgate
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on kitchens, windows & doors and plot handovers, and people most often call us about cracked sealant around new window and door frames and worktop and upstand sealant coming away.
Older homes in small places like Kingsgate often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a 12-month guarantee.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Ventilate bathrooms well, especially in the first year
- Don’t wait for the house to settle if water is getting through
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Why deal with it now?
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can phone 0345 464 0079 or send us an email with a few pictures and we’ll give you a straight answer. Around Kingsgate, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.

What sealant work cannot fix
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.

What new build mastic looks like in Kingsgate
Kingsgate is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Kingsgate, as everywhere, new build mastic is only as good as the preparation behind it.

What we’re called out for in Kingsgate
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
It’s worth asking for a quote if you see:
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
- Plot mastic for developers ahead of handover
For new homes near Broadstairs station, it’s worth checking the sealant early, while snags are still fresh.

Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
