External mastic in Little Parndon
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for movement joints filled with mortar instead of sealant and cracked joints where brick meets render or frames, on façade panels, concrete & block and joints between brick and frames.
Outbuildings, garages and conservatories around homes in places like Little Parndon add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Honest limits
Before booking, it’s worth knowing the limits too:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Why act early in Little Parndon
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In an older home around Little Parndon, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Little Parndon questions
I let a flat near Harlow Town station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do older homes in Little Parndon need their sealant replacing?
If it hasn’t been replaced for some years, it’s usually worth it. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, wherever you are.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
What does external mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email and let us know what needs doing and where.
Do you use backing rod?
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 the job changes by surface
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Keeping the joints in good condition
Aftercare is simple:
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
Don’t paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
Little Parndon buildings and the weather
Harlow, which Little Parndon is part of, is one of England’s post-war new towns. Homes here were built in phases, many of them in the post-war decades, so whole streets can have gutters, trims and wall joints reaching the end of their life together. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Little Parndon Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Harlow Town station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. In a smaller place like Little Parndon, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Tell us about any water getting in
- Clear items away from the joints we are working on
- Mention any tricky access

Advice
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
