External mastic in Lashenden, 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. We work on façade panels, render & cladding joints and copings & trims, and common reasons people get in touch are old sealant gone brittle and cracked and cracked joints where brick meets render or frames.
Around Lashenden, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.
All of our work is guaranteed for twelve months, in Lashenden and everywhere else we cover.

Lashenden buildings and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Lashenden, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. If you let a flat or house near Headcorn station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- 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
- Tell anyone working on the walls about the movement joints
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.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
FAQs for Lashenden
Will you come out to Lashenden?
Yes. Lashenden is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do external mastic in Lashenden?
Yes, Lashenden is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Why act early in Lashenden
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. Around Lashenden, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

How it works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere like Lashenden needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
