External mastic for homes and businesses in Latton
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We are often asked to deal with joints where the bead has come unstuck and leaking joints around cladding and façade panels, on render & cladding joints, concrete & block and façade panels.
Around Latton, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Surface by surface
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant is not too deep.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured for the work.
Common problems we fix in Latton
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Look out for any of the following:
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
- Panel joints letting water in
- Old sealant gone brittle and cracked
In the older streets around Church of St Andrew, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

External mastic in Latton: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Harlow, which Latton is part of, is one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so neighbouring houses often have rooflines and wall joints of the same age, wearing out at the same time.
If you look after a building such as Church Langley Community Primary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Harlow Town station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Why it’s worth doing now in Latton
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Older cottages and farmhouses around Latton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is usually more efficient than separate visits. We will give you a clear price for the lot.

Looking after it afterwards
To keep the joints looking good and working properly:
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
- Keep movement joints as flexible joints, not mortar
- Leave the joints unpainted unless we have said otherwise
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.

FAQs for Latton
I let a flat near Harlow Town station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Latton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can I do 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.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so it doesn’t stand out.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
