External mastic in Steven's Crouch
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We are often asked to deal with rain getting behind render or cladding at a joint and joints with sealant missing in places, across concrete & block, joints between brick and frames and brickwork movement joints.
External sealant needs dry, clean surfaces, so work around Steven's Crouch is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Check the sealant is paintable before painting near it
- Act on the first splits you see
- Deal with leaking gutters that soak the joints below
- Never let anyone fill a movement joint with mortar
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Do you need external mastic in Steven's Crouch?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
People generally contact us when they notice one of these:
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
Rented homes near Battle station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Why act early in Steven's Crouch
Sealing over the top of old mastic does not hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Around Steven's Crouch, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and reseal when it splits.
