New build mastic in Broadfield
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. Typical jobs include sealant that never bonded to the surface and second-fix sealing on new plots, on show homes, kitchens and plot handovers.
In smaller places like Broadfield, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
There’s a 12-month guarantee on every job.

Aftercare tips
To keep the joints looking good and working properly:
- Photograph failed sealant before it’s redone
- Do not seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
- Do not wait for the house to settle if water is getting through
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

How the job changes by 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.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
What new build mastic looks like in Broadfield
Broadfield is part of Crawley, one of the post-war new towns. Crawley has kept growing, with newer neighbourhoods added to the original town, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Older homes need their sealant and floor joints renewing, newer ones 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.
If you’ve bought a new home near Crawley station, the sealant around baths, showers and frames is worth checking in the first year or two.

Your questions about new build mastic in Broadfield
Is Broadfield in your area for new build mastic?
Yes. Our work covers London and the South East, and Broadfield is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Crawley station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Where are you based?
We work from Crawley. Our applicators cover Broadfield, along with the rest of our area.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours in a single home. A visit to Broadfield is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Clear the area around the work

Related advice
Common problems we fix in Broadfield
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
It’s worth asking for a quote if you see:
- Worktop and upstand sealant coming away
- Sealant that never bonded to the surface
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
Around Broadfield, as everywhere, new build mastic is only as good as the preparation behind it.
