About our external mastic in Bramdean
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. Common call-outs are for weeds or debris growing in open joints and rigid filler in a joint that should flex, across copings & trims, brickwork movement joints and joints between brick and frames.
Around Bramdean, 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.
Our work is backed for twelve months, in Bramdean and everywhere else we cover.

Outside joints around Bramdean
Historic houses like Hinton Ampner House (about 1.3 miles west) are a reminder that the area around Bramdean has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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 Bramdean, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What else we do in Bramdean
Looking after it afterwards
To keep the joints looking good and working properly:
- Avoid pressure-washing directly into sealant joints
- Make sure movement joints aren’t pointed over
- Ask before painting over external sealant
- Act on the first splits you see
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.
What we do, step by step
The work is kept neat and contained to the joints we’re treating. The job generally takes anything from a few hours to several days, depending on the building. Somewhere as small as Bramdean, access is often the only tricky part. 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

How the job changes by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap and keep the sealant to the right depth.
Your questions about external mastic in Bramdean
Is Bramdean in your area for external mastic?
Yes, Bramdean is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Is Bramdean within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
How long does external mastic last?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
When to call us in Bramdean
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
The problems people generally mention when they call are:
- Weeds or debris growing in open joints
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
For an older house near a landmark such as Church of St Simon and St Jude, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- Which sealant they’ll use, and why
- How hidden problems are handled
- Whether all the old sealant comes out first
- The length of the guarantee
Why act early in Bramdean
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Bramdean, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
Why book with us
- Experience in homes, commercial sites and hotels
- White, clear, grey or coloured to suit, where the product allows
- We never seal over old sealant
- 4.9 on Google from 180+ five-star reviews

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Walls that need new movement joints cut into them
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
Surfaces we seal
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
- Concrete & block
- Façade panels
- Brickwork movement joints
