About our external mastic in Riseley
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. If you have joints pointed up with cement by mistake and joints with sealant missing in places, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Riseley is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

The process
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. Somewhere as small as Riseley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Related advice
Do you need external mastic in Riseley?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Most people get in touch when they notice something like this:
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
For an older house near a landmark such as Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Act on the first splits you see
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
- Keep water from gutters off the wall
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.

What external mastic looks like in Riseley
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Stratfield Saye House (about 1.7 miles south-west) are a reminder that the area around Riseley has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Mortimer station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why it’s worth doing now in Riseley
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Older cottages and farmhouses around Riseley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Riseley questions
Do you cover Riseley for external mastic?
Yes, Riseley is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Riseley?
Yes, Riseley is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
What’s an expansion joint in brickwork?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
