- Failed sealant between panels on a façade
- Water getting into walls through failed joints
Do you need external mastic in Hickstead?
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Most people get in touch after spotting something like this:
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
Letting a property close to Burgess Hill station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- Whether you can choose the colour
- The length of the guarantee
- Whether the sealant suits the joint
- When the joint can take water or movement
External mastic in Hickstead, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you’re dealing with cracked joints where brick meets render or frames and plants rooting in failed movement joints, we can help, whatever the surface.
Somewhere as small as Hickstead, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Each job carries a 12-month guarantee, large or small.

When it isn’t the sealant
It helps to know what we cannot do too:
- Render that is blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that is more than a sealant joint can take

What affects the quote in Hickstead
The quote reflects the job in front of us. We look at:
- The old material and how stubborn it is
- The number of rooms or windows
- The type of sealant required
- Any working-time requirements on site
A few things move the cost up or down: 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.

Outside joints around Hickstead
With historic houses such as Ockenden Manor (about 3.4 miles north-east) nearby, there’s older building stock in the area around Hickstead as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to The Parish Church of St Peter include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Twineham CofE Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Near you in Hickstead
In Hickstead, that means homes and buildings near St Paul's Catholic College and the streets around them. For rail, the closest station is Burgess Hill station, about 3.1 miles east of the centre. Nearby you will also find The Dene Hospital (1.3 miles east) and Clayton Castle (4.6 miles south-east). Open spaces near Hickstead include Wolstonbury Hill and Bedelands Farm Nature Reserve.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
- Have failed joints looked at early
- Keep water from gutters off the wall
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
DIY sealant or a professional job?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Hickstead questions
Can you help a landlord with a rental near Burgess Hill station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Will you come out to Hickstead?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Hickstead needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
