The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours in a single home and we leave things clean and tidy. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- 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.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit

- Mention any sign-in or site rules at work premises

New build mastic for homes and businesses in Foots Cray
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, kitchens and skirting & floors, and common reasons people get in touch are leaking shower tray seals in a new home and sealant that never bonded to the surface.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover.
Every job comes with a 12-month guarantee.

What else we do in Foots Cray
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
What sealant work cannot fix
We will always be straight with you, so here’s what sealant can’t fix:
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.

Do you need new build mastic in Foots Cray?
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
The problems people usually mention when they call are:
- Internal frame sealant that has split
- Gaps opening as the house dries out and settles
- Cracked caulk along new skirting
- New-build shower sealant that has already split
For new homes near Sidcup station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- Whether you can choose the colour
- When the joint can take water or movement
- What product goes in the joint
- Who turns up on the day
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Foots Cray, the repair is bigger than a sealant job.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

New build mastic in Foots Cray: local notes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Foots Cray is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How the job changes by surface
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
