How we handle external mastic in Skinners Green
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. We are often asked to deal with rigid filler in a joint that should flex and panel joints letting water in, across concrete & block, brickwork movement joints and joints between brick and frames.
Somewhere as small as Skinners Green, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Do you need external mastic in Skinners Green?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
It’s worth asking for a quote if you see:
- Joints where the bead has come unstuck
- Cracked joints where brick meets render or frames
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
If you let a flat or house near Newbury station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- Which colour the sealant will be
- What insurance they hold
Common questions in Skinners Green
Is Skinners Green in your area for external mastic?
Yes. We work across London and the South East, and Skinners Green is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Newbury station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Landlord and commercial work in Skinners Green
For anyone letting property in or around Skinners Green, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Leave it or put it right?
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 problem grows beyond the joint itself. Where a wall is exposed, as many are in small places like Skinners Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

External mastic in Skinners Green: local notes
Historic houses like Benham Park (about 1.4 miles north) are a reminder that the area around Skinners Green 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as John Rankin Infant and Nursery School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Parish Church of St Michael, an extension built onto an older house moves differently, and the joint between them takes the strain.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Cracking across the wall rather than at a joint
- Damp that isn’t coming from the joint
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Skinners Green, 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.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Let us know about parking restrictions
