What sealant work cannot fix
We will always be straight with you, so here’s what new sealant won’t do:
- Render that is blown, hollow or coming away
- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

External mastic for homes and businesses in Lordington
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we don’t skip that step. We work on brickwork movement joints, concrete & block and render & cladding joints, and common reasons people get in touch are failed seals between different materials and weeds or debris growing in open joints.
Older homes in small places like Lordington may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. For a village or hamlet like Lordington, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

Related advice
Why deal with it now?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way. Where a wall is exposed, as many are in small places like Lordington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.

Surface by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Common problems we fix in Lordington
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.
The most common problems we see are:
- Leaking joints around cladding and façade panels
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
- Rigid filler in a joint that should flex
Homes close to Racton Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

External mastic in Lordington: local notes
With historic houses such as Warblington Castle (about 4.2 miles south-west) nearby, there’s older building stock in the area around Lordington as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Bourne Community College? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Southbourne station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
