How we handle new build mastic in Worcester Park
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on bathrooms & en suites, plot handovers and show homes, and people most often call us about sealant that never bonded to the surface and joints pulling apart as timber shrinks.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

What happens on the day
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a job in Worcester Park, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Mention any sign-in or site rules at work premises

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What new build mastic looks like in Worcester Park
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
Worcester Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Follow the cure time we give you
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
Common problems we fix in Worcester Park
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
The problems people usually mention when they call include:
- Skirting joints opening in the first winter
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
- Frame joints opening as the plaster dries
If you’ve bought a new home near Worcester Park station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before you book anyone
- When the joint can take water or movement
- What guarantee comes with the work
- Who turns up on the day
- Is the old sealant removed completely?
Honest limits
In fairness, there are a few things sealant won’t fix:
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
