External mastic in Salehurst, done properly
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you are dealing with joints where the bead has come unstuck and joints with sealant missing in places, we can put it right, on joints between brick and frames, brickwork movement joints and copings & trims alike.
Around Salehurst, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
Each job carries a 12-month guarantee.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Walls and rooflines in Salehurst
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Durhamford Manor (about 3.7 miles south) nearby, there’s older building stock in the area around Salehurst as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around The Parish Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Salehurst Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Salehurst questions
Is Salehurst in your area for external mastic?
Yes, Salehurst is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Salehurst?
Yes. Salehurst 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.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Cracked brickwork or render that needs a builder or plasterer
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Façade panels
Do you need external mastic in Salehurst?
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
It’s worth asking for a quote if you see:
- Joints with sealant missing in places
- Joints where the bead has come unstuck
- Rain getting behind render or cladding at a joint
- Hard, crazed mastic that has stopped moving
Letting a property close to Robertsbridge station? Then split movement joints are easy to miss on a rental until damp shows inside.

- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- How easy the joints are to reach

- Access, such as stairs, a lift or height
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
Getting a quote is simple: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.
How the visit works
At the end, we look at the finished work together. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. For a village or hamlet like Salehurst, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any parking rules near the property
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive

Why act early in Salehurst
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Salehurst, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
