About our external mastic in Lenham Forstal
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. If you are dealing with gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving, we can put it right, on concrete & block, brickwork movement joints and copings & trims alike.
External sealant needs dry, clean surfaces, so work around Lenham Forstal is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, you get the same one-year guarantee.

What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move.
How long does the job take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
When will the joints need doing again?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

Advice
Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
When to call us in Lenham Forstal
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.
The most common problems we see are:
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
- Weeds or debris growing in open joints
- Joints with sealant missing in places
For landlords with property near Lenham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- What happens if the job turns out different
- When the joint can take water or movement
- Whether you can choose the colour
- Whether VAT is included
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Never let anyone fill a movement joint with mortar
- Avoid pressure-washing directly into sealant joints
- Deal with leaking gutters that soak the joints below
- Leave the joints unpainted unless we’ve said otherwise
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants are not designed to be painted.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.

External mastic in Lenham Forstal: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

If you live in an older home near Church of the Holy Trinity, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What affects the cost of external mastic
Jobs vary more than people expect. The main factors:
- Any working-time requirements on site

Why act early in Lenham Forstal
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Lenham Forstal, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

What we cannot put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that’s more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
