New build mastic in Farnborough
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. In both, preparation makes the difference, because that’s what rushed new-build sealant generally lacks. If you have smeared, uneven beads picked up at snagging and worktop and upstand sealant coming away, we can help, whatever the surface.
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.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

New build mastic around Farnborough
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Farnborough. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- 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.
- We check every joint and leave you with the cure times.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
- Keep pictures and emails about snagging items
- Wait for the cure time before using a resealed shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
Common problems we fix in Farnborough
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry.
Most people get in touch after spotting one of these:
- New-build shower sealant that has already split
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
- Plot mastic for developers ahead of handover
For new homes near Orpington station, it’s worth checking the sealant early, while snags are still fresh.

Farnborough: your questions answered
Is parking a problem for a job in Farnborough?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
I let a flat near Orpington station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
How long does new build mastic take?
A typical job takes anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. We will confirm how long when we quote.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but other colours are available. We choose one to suit the room and agree it with you.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
