External mastic for homes and businesses in Shortfield Common
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. Common call-outs are for sealant pulling away from one side of the joint and damp patches traced to an open external joint, across copings & trims, brickwork movement joints and façade panels.
Somewhere as small as Shortfield Common, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
All our work comes with a one-year guarantee, wherever you are in Surrey.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What external mastic looks like in Shortfield Common
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Farnham Castle (about 3 miles north) are a reminder that the area around Shortfield Common has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Farnham station, outside joints that have cracked can let damp into a rental, so check them between lets.

Quotes for external mastic in Shortfield Common
We do not publish a price list, because jobs vary so much. What we look at:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- How many areas need sealing
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before sealing.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Signs you need external mastic in Shortfield Common
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
People generally contact us after spotting one of these:
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
If you look after a building such as Edgeborough School, larger buildings have long runs of movement joint that eventually need resealing.

Shortfield Common questions
Is Shortfield Common within the area you cover?
Yes, we do. 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 you cover Shortfield Common for external mastic?
Yes, Shortfield Common is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there.

For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- 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.
