What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Old Romney, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Clear the area around the work

How we handle external mastic in Old Romney
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on brickwork movement joints, concrete & block and copings & trims, and common reasons people get in touch are old sealant gone brittle and cracked and joints where the bead has come unstuck.
Older homes in small places like Old Romney may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Big or small, you get the same 12-month guarantee.

Outside joints around Old Romney
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.
For landlords with property near Appledore (Kent) station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like The Marsh Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

DIY versus a professional finish
If you’re set on DIY, put the effort into 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Do not let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
- Check external joints each spring
- Keep high-pressure jets off the joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

Why act early in Old Romney
Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Old Romney, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Common problems we fix in Old Romney
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Any of these means the joints need attention:
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Hard, crazed mastic that has stopped moving
For an older house near a landmark such as Church of St Clement, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- When the joint can take water or movement
- Is VAT in the price?
- How long the guarantee is
- Whether they’re fully insured
How the job changes by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.

Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Should I try DIY first?
Sometimes. 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.
