Rockford External Mastic
We cover Rockford for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Rain getting behind render or cladding at a joint
- Moss and dirt in joints with no sealant left
- Movement joints filled with mortar instead of sealant
What happens on the day
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Rockford, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

External mastic for homes and businesses in Rockford
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. If you are dealing with brick movement joints where the sealant has split and hard, crazed mastic that has stopped moving, we can put it right, whatever the surface.
In a village or hamlet like Rockford, 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.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Aftercare tips
Aftercare is simple:
- Ask before painting over external sealant
- Keep high-pressure jets off the joints
- Don’t let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Common problems we fix in Rockford
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Common reasons people contact us include:
- Sealant that has lost its bond to the brick or render
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
- Weeds or debris growing in open joints
If you look after a building such as Poulner Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in Rockford
Do you cover smaller places like Rockford?
Yes, we do. 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.
Is external mastic in Rockford guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Are you fully insured?
Yes, we are fully insured.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and reseal when it splits.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
When something else is needed
New sealant cannot fix everything, and we’ll tell you before we start. Sealant won’t put right:
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal
- Copings & trims
- Façade panels
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What external mastic looks like in Rockford
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Martins, an extension built onto an older house moves differently, and the joint between them takes the strain.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
