Rolvenden External Mastic
We cover Rolvenden for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Movement joints filled with mortar instead of sealant
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
How we handle external mastic in Rolvenden
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on brickwork movement joints, concrete & block and copings & trims, and common reasons people get in touch are plants rooting in failed movement joints and joints with sealant missing in places.
Older homes in small places like Rolvenden may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
Every job comes with a one-year guarantee.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
- Cutting new joints into brickwork, which is building work rather than sealant work

Rolvenden questions
Is there a guarantee on external mastic in Rolvenden?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Rolvenden in your area for external mastic?
Yes, Rolvenden 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, and we will give you a clear quote.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
How much does external mastic cost in Rolvenden?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Where do you work from?
We work from Crawley. We cover Rolvenden and the rest of Kent, along with the rest of our area.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you reach joints on upper floors?
It depends on the building. Send us photos and a rough idea of the height.
How it works
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere as small as Rolvenden, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

Related advice
Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last. Where a wall is exposed, as many are in small places like Rolvenden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How the job changes by surface
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
Common problems we fix in Rolvenden
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Look out for these signs:
- Damp patches traced to an open external joint
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
- Plants rooting in failed movement joints
If you live in an older home near Parish Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Rolvenden buildings and the weather
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. With historic houses such as Smallhythe Place (about 3.1 miles east) nearby, there’s older building stock in the area around Rolvenden as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Rolvenden Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
