How we handle external mastic in Hardham
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 where a rigid filler would soon crack. Typical jobs include rain getting behind render or cladding at a joint and rigid filler in a joint that should flex, on concrete & block, brickwork movement joints and joints between brick and frames.
External sealant needs dry, clean surfaces, so work around Hardham is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months, in Hardham and everywhere else we cover.

Questions from Hardham
Do you cover Hardham for external mastic?
Yes, Hardham is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.
Do you cover smaller places like Hardham?
Yes, Hardham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or drop us an email.

Different surfaces, different methods
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
- Avoid pressure-washing directly into sealant joints
- Don’t let climbing plants root in the sealant
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Hardham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, 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 do, step by step
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Hardham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.

Advice
Outside joints around Hardham
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Old Place Manor (about 1 mile north-east) nearby, there’s older building stock in the area around Hardham as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like St James' CofE Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Pulborough station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How we quote for external mastic
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- Any mould that needs treating
- The size of the job
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Roughly how big the job is
- The type of property
- Any access issues, like height or stairs
- A few pictures by email, if you can
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved and give you a clear price.
Do you need external mastic in Hardham?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
People normally contact us when they notice one of these:
- Movement joints filled with mortar instead of sealant
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
For an older house near a landmark such as St Botolph's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
