New Build Mastic in Hawthorn
Problem with your new-build sealant joints in Hawthorn? We remove the old material, prepare the joints and seal them properly.
- Kitchen sealant that has pulled off the wall
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
New build mastic for homes and businesses in Hawthorn
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on plot handovers, windows & doors and skirting & floors, and the jobs we see most are untidy sealant flagged on a snagging list and plot mastic for developers ahead of handover.
Work in a small place like Hawthorn just needs the journey and access planning, and once on site, the job is the same as anywhere.
Big or small, it’s backed by our 12-month guarantee in Hawthorn and across Kent.

What new build mastic looks like in Hawthorn
Hawthorn 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep water off fresh sealant until it has cured
- Ventilate bathrooms well, especially in the first year
- Check bath and shower seals every few months as the house settles
- Raise failed sealant with the developer while you are covered
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. 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. Getting it resealed properly, and any movement checked, stops it recurring.
What happens if it’s left?
A hairline gap at a skirting can wait, but a leaking seal cannot. If you are unsure which you have, ring 0345 464 0079 or email us with pictures. Around Hawthorn, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
