How we handle external mastic in Clatterford
On houses, flats and commercial buildings across Clatterford, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We are often asked to deal with movement joints with cracked, split or missing sealant and rain getting behind render or cladding at a joint, across copings & trims, render & cladding joints and façade panels.
Somewhere as small as Clatterford, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
You get a 12-month guarantee, the same in Clatterford as everywhere else we work.

Outside joints around Clatterford
Historic houses like Carisbrooke Castle (about 0.3 miles east) are a reminder that the area around Clatterford has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as St Thomas of Canterbury Catholic Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Church of St. Nicholas in Castro, an extension built onto an older house moves differently, and the joint between them takes the strain.

What else we do in Clatterford
Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Clatterford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Landlords, agents and businesses in Clatterford
We also work for property managers and facilities teams in Clatterford and across the Isle of Wight. We can quote a run of properties together, and we are fully insured.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
- Render that’s blown, hollow or coming away
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building. Somewhere like Clatterford 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Clear the area around the work

Common questions in Clatterford
Do you cover smaller places like Clatterford?
Yes. Clatterford is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with external mastic in Clatterford?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Why do you put foam in the joint first?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
How long does the job take?
That depends on the amount of work, but most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll give you a better idea when we quote.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
