External Mastic in Stubbington
Our applicators work in Stubbington on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Failed sealant between panels on a façade
- Water getting into walls through failed joints
- Joints with sealant missing in places
How it works
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job normally takes a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. For a job in Stubbington, 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.
- 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.
Before we arrive
- Tell us if parking is tricky
- Tell us about any water getting in
- Move anything stored near the joints

External mastic in Stubbington, done properly
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you have failed seals between different materials and weathered mastic that no longer stretches, we can put it right.
Around Stubbington, garages, outbuildings and extensions all add to the joints on the outside of a home. 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 something isn’t right with it in that time, tell us and we will put it right.

Stubbington buildings and the weather
Stubbington is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Crofton Anne Dale Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Fareham station, outside joints that have cracked can let damp into a rental, so check them between lets.

Why it’s worth doing now in Stubbington
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. Around Stubbington, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

When it is not the sealant
In fairness, there are a few things sealant won’t fix:
- Movement that’s more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
- Walls that need new movement joints cut into them

What we are called out for in Stubbington
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Keep an eye out for these signs:
- Sealant that has lost its bond to the brick or render
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
Homes close to Holy Rood Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Common questions in Stubbington
Does living near the coast affect external mastic in Stubbington?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Fareham station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you quote for more than one area?
Yes. Just list everything you need.
How much does external mastic cost in Stubbington?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
