External mastic in Labour-in-vain, done properly
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We’re often asked to deal with moss and dirt in joints with no sealant left and cracked joints where brick meets render or frames, across concrete & block, façade panels and render & cladding joints.
Older homes in small places like Labour-in-vain may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

How we quote for external mastic
Jobs vary more than people expect. The main factors:
- The type of sealant required
- How easy the joints are to reach
- Any mould that needs treating
- The amount of work
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What we need to know
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- Whether it’s a home or a business
- A few pictures by email, if you can
- Where the property is
We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Clear growth from the base of walls and joints
- Point out the joints to other trades
- Ask before painting over external sealant
- Keep water from gutters off the wall
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.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Labour-in-vain: your questions answered
I let a flat near Borough Green & Wrotham station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover Labour-in-vain for external mastic?
Yes. We work across London and the South East, and Labour-in-vain is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.
Why deal with it now?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. In a small place like Labour-in-vain, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What you get with us
- Anti-fungal sanitary silicone in wet areas
- Colour picked to suit the job
- We never seal over old sealant
- One-year guarantee on every job

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job normally takes anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. Somewhere like Labour-in-vain needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.

Advice
External mastic in Labour-in-vain: local notes
With historic houses such as Old Soar Manor (about 4 miles south) nearby, there’s older building stock in the area around Labour-in-vain as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Wrotham School? Then larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Borough Green & Wrotham station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St George, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
