External mastic in Rivenhall
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. Typical jobs include joints with sealant missing in places and failed sealant between panels on a façade, across concrete & block, render & cladding joints and brickwork movement joints.
External sealant needs dry, clean surfaces, so work around Rivenhall is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Get split or bare joints resealed while the damage is small
- Keep movement joints as flexible joints, not mortar
- Clear growth from the base of walls and joints
- Show decorators and builders where the movement joints are
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
What external mastic looks like in Rivenhall
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Witham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St Mary and All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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.

Rivenhall questions
Is Rivenhall within the area you cover?
Yes, Rivenhall is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Rivenhall for external mastic?
Yes. Our work covers London and the South East, and Rivenhall is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Essex.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
What information do you need?
Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
Will the new joint stand out?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Rivenhall, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- On commercial sites, let us know about site rules

Common problems we fix in Rivenhall
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Any of these means the joints need attention:
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
- Movement joints filled with mortar instead of sealant
Managing a site like Rivenhall Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

- Who turns up on the day

- The length of the guarantee
Why act early in Rivenhall
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Older cottages and farmhouses around Rivenhall can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
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. You’ll have a clear quote before any work starts.
