Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Langham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

About our external mastic in Langham
On houses, flats and commercial buildings across Langham, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. Typical jobs include sealant pulling away from one side of the joint and weathered mastic that no longer stretches, across joints between brick and frames, concrete & block and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Langham is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Your job is guaranteed for a year, as with all our work.

Questions from Langham
I let a flat near Colchester station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Will you come out to Langham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job.
How the job changes by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Outside joints around Langham
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. Historic houses like Castle House (about 2.6 miles east) are a reminder that the area around Langham has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Langham Primary School, its movement joints, gutters and trims need looking after like any other building’s. Historic houses such as Castle House, about 2.6 miles east, show how far back building around Langham goes, and older homes nearby need a sealant that suits their walls.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
When to call us in Langham
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
These are the problems we’re asked about most:
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
Letting a property close to Colchester station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
