Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.
External mastic in Sheffield Bottom, done properly
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we don’t skip that step. We work on brickwork movement joints, copings & trims and façade panels, and common reasons people get in touch are old sealant gone brittle and cracked and rain getting behind render or cladding at a joint.
In a village or hamlet like Sheffield Bottom, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Whatever the size of the job, you get the same one-year guarantee.

Will you come out to Sheffield Bottom?

What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How long does external mastic take?
A typical job takes a few hours for a handful of joints, longer for a whole elevation. We’ll confirm how long when we quote.
The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Somewhere as small as Sheffield Bottom, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for 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.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Tell us if parking is tricky

Why it’s worth doing now in Sheffield Bottom
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Sheffield Bottom can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Fix overflowing gutters above sealed joints
- Check the sealant is paintable before painting near it
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
External mastic in Sheffield Bottom: local notes
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. With historic houses such as Mapledurham House (about 4.4 miles north) nearby, there’s older building stock in the area around Sheffield Bottom as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Theale station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Church of the Holy Trinity, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Theale C.E. Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
