Signs you need new build mastic in Rottingdean
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
These are the problems we are asked about most:
- Smeared, uneven beads picked up at snagging
- Joints pulling apart as timber shrinks
- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
Around Rottingdean, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Rottingdean
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first. We work on plot handovers, bathrooms & en suites and windows & doors, and common reasons people get in touch are joints pulling apart as timber shrinks and plot mastic for developers ahead of handover.
Around Rottingdean, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Rottingdean, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Rottingdean, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before any work starts.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Use the extractor fan every time you shower
- Wipe joints with warm soapy water
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with straight away
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.

Common questions in Rottingdean
Is Rottingdean in your area for new build mastic?
Yes. Our work covers London and the South East, and Rottingdean is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
I let a flat near Moulsecoomb station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Is it worth trying it myself?
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.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
New homes and floors in Rottingdean
Rottingdean is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Moulsecoomb station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
When something else is needed
Before you book, it’s worth knowing the limits:
- Leaks from pipes, valves or wastes, which need a plumber
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
