What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Which sealant suits the joint
- Whether the work is at height
- The size of the job
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, phone 0345 464 0079 or send us an email.
How we handle external mastic in Littleworth
Getting the depth right is half the job. 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 have rigid filler in a joint that should flex and cracked joints where brick meets render or frames, we can put it right, on brickwork movement joints, façade panels and joints between brick and frames alike.
External sealant needs dry, clean surfaces, so work around Littleworth is planned for dry weather. 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.

What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Where a wall is exposed, as many are in small places like Littleworth, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.

Your questions about external mastic in Littleworth
What guarantee comes with external mastic in Littleworth?
All our work, in Littleworth and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is Littleworth within the area you cover?
Yes, Littleworth is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall. If it has already been filled, we can generally cut it out and reseal it.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
How long will you be here?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Littleworth buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as St Michael and All Angels Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Somewhere as small as Littleworth, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- 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.
Getting ready for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions

Advice
What we are called out for in Littleworth
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
If you can see any of these, it’s time to have the joints looked at:
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
Managing a site like Jolesfield CofE Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
- Whether you can choose the colour
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
