External & façade joints in Bocking, Essex
External mastic across Bocking and nearby, with old sealant always removed completely and a 12-month guarantee.
- Water getting into walls through failed joints
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Avoid pressure-washing directly into sealant joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
External mastic in Bocking, done properly
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. If you are dealing with gaps where render, brick and frames meet and joints with sealant missing in places, we can put it right.
Outbuildings, garages and conservatories around homes in places like Bocking add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Every job is covered by a one-year guarantee, wherever you are in Essex.

Walls and rooflines in Bocking
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Braintree station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as St Francis Catholic Primary School, larger buildings have long runs of movement joint that eventually need resealing. Homes close to Church of St Peter include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In an older home around Bocking, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why Bocking customers choose us
- Anti-fungal sanitary silicone in wet areas
- Quality sealants from Arbo and Everbuild

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Bocking questions

Do you work for landlords with property near Braintree station?

What is a movement joint?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
How long does external mastic last?
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.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Give us some details and we will confirm the access.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
