External & façade joints in Warlingham, Surrey
Our applicators work in Warlingham on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Weathered mastic that no longer stretches
- Leaking joints around cladding and façade panels
- Failed seals between different materials
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
External mastic in Warlingham, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. If you are dealing with rigid filler in a joint that should flex and movement joints with cracked, split or missing sealant, we can help, whatever the surface.
Houses in smaller places like Warlingham can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
Whatever the size of the job, you get the same one-year guarantee in Warlingham and across Surrey.

Honest limits
We will always be straight with you, so here’s what sealant can’t fix:
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
- Copings & trims
- Façade panels
- Brickwork movement joints
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
- Avoid pressure-washing directly into sealant joints
- Ask before painting over external sealant
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
What affects the cost of external mastic
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- How easy the joints are to reach
- Any working-time requirements on site
- The amount of work
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- Where the job is, and your postcode
- Photos by email, if that is easy
- Whether it has been sealed before
- How we’d reach the joints
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or email us and describe the job.
Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. In a smaller place like Warlingham, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
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.

Outside joints around Warlingham
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Addington Palace (about 3.5 miles north) nearby, there’s older building stock in the area around Warlingham as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to Church of All Saints include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Upper Warlingham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Warlingham Village Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Warlingham: your questions answered
Is Warlingham within the area you cover?
Yes, Warlingham is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Upper Warlingham station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
What is backing rod for?
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.
How long does external mastic take?
A typical job takes a few hours for a handful of joints, longer for a whole elevation, including the preparation. Your quote will say how long we expect yours to take.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Tell us what the building has when you get in touch.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a handful of joints, longer for a whole elevation. A visit to Warlingham is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
