External mastic for homes and businesses in Salters Heath
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. If you’re dealing with moss and dirt in joints with no sealant left and hard, crazed mastic that has stopped moving, we can help, on render & cladding joints, brickwork movement joints and copings & trims alike.
Around Salters Heath, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
All our work is covered by a 12-month guarantee.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Walk round the building once a year and look at the joints
- Do not let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
- Deal with leaking gutters that soak the joints below
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
Outside joints around Salters Heath
Historic houses like The Vyne (about 1.5 miles south-east) are a reminder that the area around Salters Heath has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Pamber Priory include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Bramley (Hants) station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like The Priory Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Why act early in Salters Heath
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Around Salters Heath, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.

Your questions about external mastic in Salters Heath
Do you cover Salters Heath for external mastic?
Yes. Our work covers London and the South East, and Salters Heath is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Salters Heath?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building, and the area is left clean. Somewhere as small as Salters Heath, 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’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height
