How we handle external mastic in Little Chart
On houses, flats and commercial buildings across Little Chart, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on copings & trims, joints between brick and frames and façade panels, and people most often call us about joints pointed up with cement by mistake and sealant that has lost its bond to the brick or render.
External sealant needs dry, clean surfaces, so work around Little Chart is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Why it’s worth doing now in Little Chart
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Little Chart, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What happens on the day
At the end, we look at the finished work together. The visit itself usually takes anything from a few hours to several days, depending on the building, depending on how much there is to do. Somewhere as small as Little Chart, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- 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.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Keep pets and children clear of the area while we work

Looking after it afterwards
To keep the joints looking good and working properly:
- Clear growth from the base of walls and joints
- Keep high-pressure jets off the joints
- Make sure movement joints aren’t pointed over
- Leave the joints unpainted unless we have said otherwise
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Different surfaces, different methods
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Walls and rooflines in Little Chart
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Godinton House (about 2.6 miles south-east) nearby, there’s older building stock in the area around Little Chart as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Your questions about external mastic in Little Chart
Do you cover smaller places like Little Chart?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Charing station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and reseal when it splits.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.

Common problems we fix in Little Chart
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Signs it’s time to call us include:
- Leaking joints around cladding and façade panels
- Hard, crazed mastic that has stopped moving
- Joints pointed up with cement by mistake
- Plants rooting in failed movement joints
Rented homes near Charing station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
