Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
How we handle external mastic in Hell Corner
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, so it bonds to the two sides only and can stretch. We are often asked to deal with cracked joints where brick meets render or frames and weathered mastic that no longer stretches, across façade panels, joints between brick and frames and copings & trims.
In a village or hamlet like Hell Corner, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
All of our work is guaranteed for twelve months, in Hell Corner and everywhere else we cover.

External mastic in Hell Corner: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Stargroves (about 2.6 miles south-east) nearby, there’s older building stock in the area around Hell Corner as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Inkpen Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Laurence include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cracks in the bricks or render themselves, away from the joints
- 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.

Landlords, agents and businesses in Hell Corner
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
When to call us in Hell Corner
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Look out for any of the following:
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
- Cracked joints where brick meets render or frames
- Panel joints letting water in
Rented homes near Kintbury station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What we do, step by step
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes anything from a few hours to several days, depending on the building. Somewhere as small as Hell Corner, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for 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.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

Questions from Hell Corner
Can you help a landlord with a rental near Kintbury station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Hell Corner?
Yes. Hell Corner is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How much does external mastic cost in Hell Corner?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Do you work at height?
Each building is different. Tell us the height, the number of joints and what’s below them.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Act on the first splits you see
- Avoid pressure-washing directly into sealant joints
- Make sure movement joints are not pointed over
- Show decorators and builders where the movement joints are
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
