What new build mastic looks like in Angmering-on-Sea
Angmering-on-Sea is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Angmering-on-Sea, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common questions in Angmering-on-Sea
Can you do new build mastic in Angmering-on-Sea?
Yes, Angmering-on-Sea is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Angmering-on-Sea?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it worth resealing while the house is still settling?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.

Related advice
Why act early in Angmering-on-Sea
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Angmering-on-Sea can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

See our cost guide and our reviews.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Clean sealant with mild detergent, not abrasives
- Wait for the cure time before using a resealed shower
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated pictures
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day to cure enough for use.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
How the job changes by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Do you need new build mastic in Angmering-on-Sea?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry.
People generally contact us when they notice something like this:
- Gaps behind new kitchen upstands
- Sealant work across a run of new homes
- Internal frame sealant that has split
- Sealant that never bonded to the surface
For new homes near Angmering station, it’s worth checking the sealant early, while snags are still fresh.

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, and the work is guaranteed for a year.
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.
