About our external mastic in Pennington
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. We are often asked to deal with leaking joints around cladding and façade panels and cracked joints where brick meets render or frames, on brickwork movement joints, render & cladding joints and façade panels.
Outbuildings, garages and conservatories around homes in places like Pennington add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How the job changes by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
When something else is needed
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Damp that isn’t coming from the joint
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

FAQs for Pennington
Does the coastal weather in Pennington affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Is Pennington within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Should I try it myself first?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Do you need external mastic in Pennington?
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
People normally contact us when they notice one of these:
- Failed seals between different materials
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
If you live in an older home near Church of St Mark, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- Whether they’re fully insured
- Whether they seal over old material or remove it
- What happens if the job turns out different
- How the joint is cleaned and prepared
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. A visit to Pennington is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- 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
- Mention any tricky access
- Clear items away from the joints we are working on
- Let us know about parking restrictions

What external mastic looks like in Pennington
Pennington 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Priestlands School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Lymington Town station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
