External & façade joints in Little Heath, Essex
Problem with your movement joints in Little Heath? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Leaking joints around cladding and façade panels
- Damp patches traced to an open external joint
- Old sealant gone brittle and cracked
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. In a smaller place like Little Heath, 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.
Some things make a job bigger or smaller: 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.
Why book with us
- 12-month guarantee on every job
- Tidy, careful work

About our external mastic in Little Heath
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint does not stand out. We work on joints between brick and frames, façade panels and render & cladding joints, and common reasons people get in touch are joints with sealant missing in places and movement joints filled with mortar instead of sealant.
In and around Little Heath, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

External mastic in Little Heath: local notes
With historic houses such as Valentines Mansion (about 2.6 miles west) nearby, there’s older building stock in the area around Little Heath 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Chadwell Heath station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Grove Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near St Mark's, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Clear growth from the base of walls and joints
- Avoid pressure-washing directly into sealant joints
- Tell anyone working on the walls about the movement joints
- Act on the first splits you see
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Surface by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.
How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. Parking around Little Heath is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Let us know about stairs, lifts or work at height

Common questions in Little Heath

Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
How much does external mastic cost in Little Heath?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it doesn’t stand out.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Honest limits
Before booking, it’s worth knowing the limits too:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
- Render that is blown, hollow or coming away
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
