Sulhamstead Abbots External Mastic
We cover Sulhamstead Abbots for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

- Gaps where render, brick and frames meet

External mastic in Sulhamstead Abbots
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you’re dealing with joints pointed up with cement by mistake and joints with sealant missing in places, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Sulhamstead Abbots is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Sulhamstead Abbots, access is normally the main thing to plan. 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

Why it’s worth doing now in Sulhamstead Abbots
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Sulhamstead Abbots, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Common questions in Sulhamstead Abbots
Do you cover smaller places like Sulhamstead Abbots?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Theale station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. We’ll reseal it with a flexible sealant.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Surface by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it and keep the sealant to the right depth.
What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.
What we seal
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Façade panels

Sulhamstead Abbots buildings and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Sulhamstead and Ufton Nervet School? Then larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Theale station, outside joints that have cracked can let damp into a rental, so check them between lets.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Tell anyone working on the walls about the movement joints
- Act on the first splits you see
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Common problems we fix in Sulhamstead Abbots
Sometimes a movement joint was filled with mortar or a rigid filler, 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.
Any of these means the joints need attention:
- Sealant pulling away from one side of the joint
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Cracked joints where brick meets render or frames
For an older house near a landmark such as Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
