External & façade joints in Drayton, Portsmouth
External mastic for Drayton, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Movement joints filled with mortar instead of sealant
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Drayton, 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.

How we handle external mastic in Drayton
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. If you have movement joints filled with mortar instead of sealant and weeds or debris growing in open joints, we can help, whatever the surface.
In a smaller place like Drayton, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Walls and rooflines in Drayton
Drayton 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. Historic houses like Warblington Castle (about 3.4 miles east) are a reminder that the area around Drayton has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near Drayton Methodist Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Springfield School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the building. In a smaller place like Drayton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at every joint and agree a colour to suit the wall.
- 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.
How to prepare
- Keep children and pets away from the work area
- Clear items away from the joints we’re working on
- Mention any tricky access

Advice
How to look after the new joints
So the new joints stay in good condition:
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
When to call us in Drayton
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, and it tears off the sides.
Signs it’s time to call us include:
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
For landlords with property near Cosham station, outside joints that have cracked can let damp into a rental, so check them between lets.

Quotes for external mastic in Drayton
Every job gets its own quote. This is what makes a difference:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- The product the joint needs
- Working hours on commercial sites
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
To help us quote quickly, let us know:
- The rough size of the job
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- The address or postcode of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- Failed render or damaged cladding panels
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

Your questions about external mastic in Drayton
Will you come out to Drayton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Cosham station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
