About our new build mastic in Kings Hill
Across Kings Hill, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you’re dealing with skirting joints opening in the first winter and leaking shower tray seals in a new home, we can help, whatever the surface.
If you’ve bought a new home in or near Kings Hill, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Every job is covered by a one-year guarantee, wherever you are in Kent.

What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Around Kings Hill, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- 20+ years of sealant experience

Kings Hill: your questions answered
Do you cover Kings Hill for new build mastic?
Yes, Kings Hill is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Kings Hill?
Yes, Kings Hill is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.
Where are you based?
We work from Crawley. We cover Kings Hill and the rest of Kent.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Keep water off fresh sealant until it has cured
- Keep photos and emails about snagging items
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What we’re called out for in Kings Hill
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Signs it’s time to call us include:
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
If you’ve bought a new home near West Malling station, the sealant around baths, showers and frames is worth checking in the first year or two.

- What guarantee comes with the work
- How the surfaces are prepared before sealing
