Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
External mastic in Crofton
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. We work on brickwork movement joints, render & cladding joints and copings & trims, and people most often call us about leaking joints around cladding and façade panels and movement joints filled with mortar instead of sealant.
In a village or hamlet like Crofton, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, you get the same 12-month guarantee in Crofton and across Hampshire.

Towns and villages near Crofton
What else we do in Crofton
Walls and rooflines in Crofton
Crofton is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Crofton School, larger buildings have long runs of movement joint that eventually need resealing. 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.

- Access, such as stairs, a lift or height

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. Somewhere as small as Crofton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

Advice
Questions from Crofton
Do you cover smaller places like Crofton?
Yes, Crofton is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect external mastic in Crofton?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly.
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.
Can you seal joints between two different materials?
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.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
Why act early in Crofton
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. In a small place like Crofton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

Signs you need external mastic in Crofton
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Common reasons people contact us include:
- Joints pointed up with cement by mistake
- Panel joints letting water in
- Hard, crazed mastic that has stopped moving
- Weeds or debris growing in open joints
If you live in an older home near Peel Common Mission Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
- How long to leave it before use
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
How to look after the new joints
After the cure time, these simple habits help:
- Check the sealant is paintable before painting near it
- Don’t let climbing plants root in the sealant
- Act on the first splits you see
- Point out the joints to other trades
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
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.
