External Mastic in Nursted

- Joints with sealant missing in places
- Gaps where render, brick and frames meet
External mastic in Nursted, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We work on façade panels, joints between brick and frames and copings & trims, and the jobs we see most are water getting into walls through failed joints and moss and dirt in joints with no sealant left.
Outside joints can only be sealed when they’re dry, so work in Nursted is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Nursted can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What external mastic looks like in Nursted
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Uppark (about 2.5 miles south-east) nearby, there’s older building stock in the area around Nursted as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Uppark, about 2.5 miles south-east, is one of the historic houses in the wider area around Nursted. Letting a property close to Petersfield station?

When it isn’t the sealant
We will always be straight with you, so here’s what new sealant won’t do:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them

What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access for a typical job. In a small place like Nursted, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires 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
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

What else we do in Nursted
Common questions in Nursted
Do you cover smaller places like Nursted?
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.
Do you work for landlords with property near Petersfield station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How to look after the new joints
Aftercare is simple:
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
- Deal with leaking gutters that soak the joints below
- Make sure movement joints aren’t pointed over
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
