What sealant work cannot fix
New sealant can’t fix everything, and we’ll tell you before we start. Sealant will not put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that is blown, hollow or coming away
- Damp that isn’t coming from the joint

About our external mastic in North Hayling
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. Typical jobs include joints with sealant missing in places and old sealant gone brittle and cracked, across render & cladding joints, copings & trims and joints between brick and frames.
In a village or hamlet like North Hayling, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, it’s backed by our one-year guarantee.

Common questions in North Hayling
Will you come out to North Hayling?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Warblington station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before any work starts.
Do you use backing rod?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
How do you reach high-level joints?
Each building is different. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
External mastic in North Hayling: local notes
North Hayling is close to 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 Warblington Castle (about 1.5 miles north) are a reminder that the area around North Hayling has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Warblington station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as The Hayling College, larger buildings have long runs of movement joint that eventually need resealing.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Never let anyone fill a movement joint with mortar
- Deal with leaking gutters that soak the joints below
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
Signs you need external mastic in North Hayling
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Keep an eye out for any of the following:
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
- Movement joints filled with mortar instead of sealant
- Cracked joints where brick meets render or frames
Homes close to Church of St Peter include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. Older cottages and farmhouses around North Hayling can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What the job involves on each surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
