New build mastic in Gomshall
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation, because that’s what rushed new-build sealant normally lacks. Common call-outs are for new-build shower sealant that has already split and gaps between new skirting and floors, across kitchens, bathrooms & en suites and windows & doors.
Somewhere as small as Gomshall, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
We stand behind the work with a 12-month guarantee.

Questions from Gomshall
Do you cover smaller places like Gomshall?
Yes, Gomshall is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do new build mastic in Gomshall?
Yes, Gomshall is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
How long does the job take?
A typical job takes a few hours for most snagging lists, longer for a run of plots. Your quote will say how long we expect yours to take.
Is there a guarantee?
Yes. All our work carries our one-year guarantee.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on the number of plots. In a small place like Gomshall, access is usually the main thing to plan.

- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.

What new build mastic looks like in Gomshall
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.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
- Act quickly if a seal starts to leak
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Signs you need new build mastic in Gomshall
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Keep an eye out for these signs:
- Joints pulling apart as timber shrinks
- Second-fix sealing on new plots
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
For new homes near Gomshall station, it’s worth checking the sealant early, while snags are still fresh.
