The cracks that come back every summer in Burgess Hill, and how to stop them
The Brighton Plasterer covers plastering across Burgess Hill and RH15. The town sits on Weald clay, so a lot of the work involves cracks that reopen each year, extension junctions and new build finishing. James identifies which kind of crack you have before deciding how to fix it.
Plastering in Burgess Hill, and what is different about it
Burgess Hill sits on Weald clay, and the clay is why the phone rings. Ground that shrinks through a dry summer and swells again through winter moves a house very slightly every year, and plaster is the least forgiving thing in the building. The cracks turn up in the same places each time: over openings, in the corners of ceilings, and along the line where an extension was joined on.
Not every crack means the same thing, and the fix depends entirely on which one you have. A hairline that follows a board joint is a taping failure and wants the joint opened up, re-taped and skimmed. A crack that steps diagonally away from a window corner is the building telling you it has moved. A wide one that opens in August and closes again in February is seasonal clay. Filling all three the same way is exactly why people end up decorating the same wall four years running.
Extension work is the other half of the diary in RH15. Families here extend rather than move, and the plastering side of that is predictable: new blockwork or board brought flat, ceilings finished, and the junction with the original house made to disappear. That junction is where two structures on different foundations meet, so it gets reinforcement carried right across the change or, where the movement is real, a proper joint that lets the two sides shift without tearing the finish apart.
New build and site work runs steadily on the edges of the town. Plastering to a programme is a different discipline to a domestic job: plots handed over in sequence, other trades working around you, tolerances checked, and a site manager who needs a date he can rely on. It also means being willing to say that a background is not ready. A wall still holding construction moisture, or a board run that has not been fixed properly, is not improved by putting a finish on it.

What Burgess Hill needs watching for
Diagnose the crack first
A taping failure, a movement crack and seasonal clay shrinkage all look similar and need completely different repairs. Which one you have decides the price and whether it stays fixed.
Joints where movement is real
Where two structures on different foundations meet, a designed joint lets them move independently. Reinforcing straight across a genuinely moving junction only delays the same crack.
Ready to take a finish
New blockwork holding construction moisture and badly fixed board are both flagged, not skimmed. A finish laid on an unready background fails and the plasterer gets the blame.
How the job runs
Step by step in Burgess Hill
The order below is how a plastering job actually runs on the kind of property Burgess Hill is made of. For the full method and the materials behind it, see the plastering page.
01Read the cracking
Each crack is traced along its length and checked against the structure behind it, because a line that follows a board joint needs a different repair to one stepping from a corner.
02Open and reinforce
Failed joints are cut open, re-taped or meshed, and reinforcement is carried across any change of background, so the repair bridges the weakness rather than sitting on top of it.
03Float new work flat
Extension walls and ceilings are dubbed out and ruled off until a straight edge sits flat, with the level carried through to match the original house at the junction.
04Skim across the join
The finish is laid continuously through the junction rather than stopped at it, then trowelled up so the change between new and old work does not show under a light.
Straight answers
When it is not the right answer here
- If a crack is caused by real structural movement, plastering is cosmetic and the movement needs looking at first.
- A new blockwork wall that is still wet from construction is not ready for a finish coat, whatever the programme says.
- Damp inland is usually a raised border, a blocked gutter or condensation, so it gets diagnosed before anything is quoted.
Plastering, Burgess Hill
Plastering in Burgess Hill, questions answered
What people in Burgess Hill ask before booking plastering, answered properly rather than in one line.
How do I tell a clay movement crack from a board joint crack?
A board joint crack runs dead straight along a regular line, following the edges of the sheets. Seasonal clay cracking usually widens in late summer and closes again in winter, and often steps away from a door or window corner rather than running straight.
Will re-skimming a wall stop the crack coming back?
Only if the cause has been dealt with. A skim over a failed joint or a moving junction is a cosmetic fix that lasts until the next dry summer. The repair has to reach the weakness underneath.
What order should extension plastering happen in?
After the roof is on, the windows are in and the first fix is complete, and ideally once the blockwork has given up its construction moisture. Plastering too early in the build is one of the most common causes of failed finishes.
How long does a Burgess Hill extension take to plaster and dry?
A typical single storey rear extension is one to two days to skim out including ceilings. Allow five to seven days before decorating, and longer if the blockwork or screed is still releasing moisture into the room.
Do you work to a developer's programme in RH15?
Yes. Plots are skimmed in sequence, coordinated around the other trades, and finished to the tolerances a site manager expects. James also says when a background is not ready, which saves everybody a return visit.
Is my new build wall too damp to plaster?
It can be, particularly in the first months after blockwork goes up or a screed is laid. Plaster applied over construction moisture blisters and loses adhesion. A meter reading takes a minute and settles the question.
Do you plaster ceilings in modern houses or just board them?
Both, depending on what the house has. Where ceilings are boarded and taped, they can be skimmed to a smooth finish that takes emulsion far better. Where boards are loose or badly jointed, they are refixed first.
