New build mastic in Luxted
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you are dealing with cracked caulk along new skirting and sealant work across a run of new homes, we can put it right.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Common questions in Luxted
Is parking an issue for new build mastic in Luxted?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you do new build mastic in Luxted?
Yes. We work across London and the South East, and Luxted is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
How do I get a quote for new build mastic in Luxted?
Size, access and the old material all affect the cost. Call for a quick quote.
When is the best time to reseal in a new build?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Should I try it myself first?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
Aftercare is simple:
- Check bath and shower seals every few months as the house settles
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with straight away
- Avoid running a DIY bead over the old one
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day before water reaches them.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Joints and finishes in Luxted homes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Chelsfield station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. In a London area like Luxted, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

Honest limits
In fairness, some problems need a different trade:
- Baths and trays that move too much for sealant to cope with
- Broken tiles or a split tray
- Leaking fittings rather than failed sealant
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

Signs you need new build mastic in Luxted
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
If you can see any of these, it’s time to have the joints looked at:
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
- Worktop and upstand sealant coming away
Luxted is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
