Do you need external mastic in Whitehill?
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we are asked about most:
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
- Panel joints letting water in
- Plants rooting in failed movement joints
In the older streets around Church of St Peter and St Paul, an extension built onto an older house moves differently, and the joint between them takes the strain.

How we handle external mastic in Whitehill
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. Common call-outs are for joints where the bead has come unstuck and panel joints letting water in, on concrete & block, copings & trims and render & cladding joints.
Older homes in small places like Whitehill may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When it is not the sealant
Before you book, it’s worth knowing the limits:
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work

External mastic in Whitehill: local notes
With historic houses such as Belmont House and Gardens (about 2.4 miles south-west) nearby, there’s older building stock in the area around Whitehill as well as newer homes. 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.
Managing a site like Ospringe Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Faversham station, split movement joints are easy to miss on a rental until damp shows inside.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
If you manage several properties in or around Whitehill, several properties can be quoted together. Just tell us the addresses and what each one needs.
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Whitehill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Whitehill questions
Can you do external mastic in Whitehill?
Yes. We work across London and the South East, and Whitehill is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Whitehill?
Yes, Whitehill is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move, and it should be sealed with a flexible sealant.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
How do I get a quote for external mastic in Whitehill?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
How to look after the new joints
After the cure time, these simple habits help:
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we have said otherwise
- Get split or bare joints resealed while the damage is small
- Keep soil, plants and ivy away from the joints
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.

How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the building. For a village or hamlet like Whitehill, 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.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
