Hangleton buildings and the weather
Hangleton is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Portslade Manor (about 0.9 miles south-west) are a reminder that the area around Hangleton has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Portslade station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Homes close to St Helen's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

How we handle external mastic in Hangleton
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. If you have old sealant gone brittle and cracked and joints pointed up with cement by mistake, we can put it right.
Outbuildings, garages and conservatories around homes in places like Hangleton add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
Big or small, you get the same one-year guarantee.

Quotes for external mastic in Hangleton
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- The size of the job
- How much old sealant there is and how hard it is to remove
- The product the joint needs
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Whether it’s a home or a business
- Roughly how big the job is
- Any previous sealing or DIY work

Surface by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the building. For a job in Hangleton, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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.
Getting ready for the visit
- Tell us if parking is tricky
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

When something else is needed
To be straight with you, some problems need a different trade:
- Render that’s blown, hollow or coming away
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.

Signs you need external mastic in Hangleton
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Look out for these signs:
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
For site and facilities teams at buildings such as Hangleton Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Aftercare tips
So the new joints stay in good condition:
- Ask before painting over external sealant
- Get split or bare joints resealed while the damage is small
- Do not let climbing plants root in the sealant
- Keep movement joints as flexible joints, not mortar
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
FAQs for Hangleton

Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
