- Rain getting behind render or cladding at a joint
- Old sealant gone brittle and cracked
What we do, step by step
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access from start to finish. Somewhere like Mill Corner 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.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive

Advice
External mastic in Mill Corner, done properly
On houses, flats and commercial buildings across Mill Corner, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Typical jobs include brick movement joints where the sealant has split and old sealant gone brittle and cracked, across concrete & block, façade panels and copings & trims.
Around Mill Corner, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Whatever the size of the job, it’s backed by our one-year guarantee in Mill Corner and across East Sussex.

What should I tell you?

Can I do 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 is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.

Outside joints around Mill Corner
Historic houses like Great Dixter (about 1.2 miles north) are a reminder that the area around Mill Corner has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Doleham station? Then split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Northiam Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Mill Corner, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Why us?
- Domestic, commercial and hotel work
- An ARBOMaster approved applicator
- Old sealant always removed completely
- Sanitary silicone with an anti-fungal additive in wet areas

Surface by surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
When to call us in Mill Corner
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 sealant never bonds properly.
Any of these means the joints need attention:
- Joints where the bead has come unstuck
- Joints with sealant missing in places
- Rigid filler in a joint that should flex
- Weathered mastic that no longer stretches
Great Dixter, about 1.2 miles north, is one of the historic houses in the wider area around Mill Corner.
