External mastic in Richborough Port, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. If you have brick movement joints where the sealant has split and failed seals between different materials, we can put it right.
External sealant needs dry, clean surfaces, so work around Richborough Port is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

FAQs for Richborough Port
Do you work for landlords with property near Thanet Parkway station?
Yes. We work for letting agents and landlords as well as homeowners. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Richborough Port?
Yes. Richborough Port is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What external mastic looks like in Richborough Port

Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Quex Park (about 4.3 miles north) nearby, there’s older building stock in the area around Richborough Port as well as newer homes.

Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Around Richborough Port, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.

Signs you need external mastic in Richborough Port
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
People usually contact us after spotting something like this:
- Hard, crazed mastic that has stopped moving
- Leaking joints around cladding and façade panels
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
For site and facilities teams at buildings such as Sir Roger Manwood's School, its movement joints, gutters and trims need looking after like any other building’s.

Different surfaces, different methods
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Tell us what the building has when you get in touch.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep soil, plants and ivy away from the joints
- Tell anyone working on the walls about the movement joints
- Never let anyone fill a movement joint with mortar
- Act on the first splits you see
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
