External & façade joints in Compton, West Berkshire
We cover Compton for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
- Joints pointed up with cement by mistake
External mastic for homes and businesses in Compton
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. If you’re dealing with weathered mastic that no longer stretches and sealant pulling away from one side of the joint, we can put it right, on render & cladding joints, joints between brick and frames and concrete & block alike.
Outside joints can only be sealed when they’re dry, so work in Compton is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes as standard.

Aftercare tips
So the new joints stay in good condition:
- Keep water from gutters off the wall
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
- Point out the joints to other trades
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.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. Somewhere like Compton needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Advice

More services for Compton
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a small place like Compton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Signs you need external mastic in Compton
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
The most common problems we see are:
- Weathered mastic that no longer stretches
- Joints with sealant missing in places
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
In the older streets around Church of St Mary and St Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant.

When something else is needed
We will not take on work that won’t last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
- Render that is blown, hollow or coming away
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

External mastic in Compton: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Compton C.E. Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Common questions in Compton
Can you do external mastic in Compton?
Yes, Compton is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Is Compton within the area you cover?
Yes. Compton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Should I try DIY first?
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.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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.
Different surfaces, different methods
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
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.
