Rawreth External Mastic
External mastic across Rawreth and nearby, with every bit of old sealant taken out first and a one-year guarantee.
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
- Gaps where render, brick and frames meet
External mastic in Rawreth
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. If you are dealing with sealant pulling away from one side of the joint and hard, crazed mastic that has stopped moving, we can put it right, on brickwork movement joints, concrete & block and façade panels alike.
Outside joints can only be sealed when they’re dry, so work in Rawreth is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Outside joints around Rawreth
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 Church of St Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Battlesbridge station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Our Lady of Ransom Catholic Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Rawreth is about 2 miles north-west of Rayleigh, in Essex. Rawreth gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Our Essex coverage runs to 644 places, and Rawreth is one of them. For nearby work, see our Chelmsford page.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Walk round the building once a year and look at the joints
- Keep movement joints as flexible joints, not mortar
- Ask before painting over external sealant
- Deal with leaking gutters that soak the joints below
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Rawreth needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height

Advice
Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
What we cannot put right
Before you book, it’s worth knowing the limits:
- Failed render or damaged cladding panels
- Subsidence or other structural problems
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The number of rooms or windows
- Any mould that needs treating
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 to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:

- Roughly how big the job is
- The problem you’ve noticed
We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details.
