What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Gestingthorpe, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
How long will you be here?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Aftercare tips
Looking after new joints is easy:
- Look over the joints every year, ideally after winter
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
- Leave the joints unpainted unless we have said otherwise
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
How the job changes by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Gestingthorpe buildings and the weather
With historic houses such as Hedingham Castle (about 2.4 miles south-west) nearby, there’s older building stock in the area around Gestingthorpe as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you let a flat or house near Sudbury (Suffolk) station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of St Mary the Virgin include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
