New-build mastic & snagging in Hampton Wick, Greater London
New build mastic across Hampton Wick and nearby, with old sealant always removed completely and a 12-month guarantee.
- Gaps behind new kitchen upstands
- Cracked sealant around new window and door frames
- Beads laid onto grit and dust from the build
Can I do it myself?
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. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
New build mastic in Hampton Wick
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 skirting & floors, bathrooms & en suites and windows & doors, and common reasons people get in touch are sealant applied over dusty or wet surfaces and cracks appearing as a new home settles.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover.
Your job is guaranteed for a year, as with all our work.

Questions from Hampton Wick
Is parking an issue for new build mastic in Hampton Wick?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I let a flat near Hampton Wick station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Who should fix failed sealant in a new build?
Report it to the builder first while you are covered. If it isn’t resolved, we can reseal it properly.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Will you just run a new bead over the existing one?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.

When to call us in Hampton Wick
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Look out for any of the following:
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
Hampton Wick is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

- How much experience the applicator has

What new build mastic looks like in Hampton Wick
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
If you’ve bought a new home near Hampton Wick station, the sealant around baths, showers and frames is worth checking in the first year or two.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Record problems with dated pictures
- Resist patching a failed seal with a tube from the DIY shop
- Act quickly if a seal starts to leak
- Check bath and shower seals every few months as the house settles
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
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.
What the job involves on each surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Honest limits
We will not take on work that will not last, so these are the limits:
- Broken tiles or a split tray
- Leaking fittings rather than failed sealant
- Movement caused by a poorly fitted tray or bath
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
