Surface by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. We reseal them with a sealant suited to the panel material.
External mastic in Pett Bottom
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we do not skip that step. If you are dealing with movement joints with cracked, split or missing sealant and rain getting behind render or cladding at a joint, we can put it right, on concrete & block, façade panels and render & cladding joints alike.
External sealant needs dry, clean surfaces, so work around Pett Bottom is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You get a 12-month guarantee, the same in Pett Bottom as everywhere else we work.

Why act early in Pett Bottom
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Where a wall is exposed, as many are in small places like Pett Bottom, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is generally more efficient than separate visits. We will give you a clear price for the lot.

External mastic in Pett Bottom: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Mary include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Schools such as Simon Langton Grammar School for Boys are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Bekesbourne station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Point out the joints to other trades
- Don’t let climbing plants root in the sealant
- Wash walls gently around the sealant
- Leave the joints unpainted unless we have said otherwise
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Pett Bottom needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Move anything stored near the joints

Common questions in Pett Bottom
Is Pett Bottom in your area for external mastic?
Yes, Pett Bottom is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is Pett Bottom 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.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
