Charing Hill External Mastic
We cover Charing Hill for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
How we handle external mastic in Charing Hill
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. We work on brickwork movement joints, render & cladding joints and concrete & block, and the jobs we see most are old sealant gone brittle and cracked and joints with sealant missing in places.
Somewhere as small as Charing Hill, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Honest limits
In fairness, some problems need a different trade:
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none

Questions from Charing Hill
Can you help a landlord with a rental near Charing station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Charing Hill?
Yes, Charing Hill is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
What the job involves on each surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Do you need external mastic in Charing Hill?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Look out for these signs:
- Damp patches traced to an open external joint
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
- Weeds or debris growing in open joints
For an older house near a landmark such as Church of St Peter and St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why act early in Charing Hill
A failed movement joint lets water into the wall, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Older cottages and farmhouses around Charing Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- How many areas need sealing
- Which sealant suits the joint
- The number and length of the joints
- The old material and how stubborn it is
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know

Charing Hill buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Godinton House (about 4.2 miles south) are a reminder that the area around Charing Hill has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Charing 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 Charing Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What else we do in Charing Hill
The process
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work normally takes anything from a few hours to several days, depending on the building. In a small place like Charing Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
