Murrell Green External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Murrell Green and across Hampshire. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Water getting into walls through failed joints
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Murrell Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can

How we handle external mastic in Murrell Green
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. If you have hard, crazed mastic that has stopped moving and leaking joints around cladding and façade panels, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Murrell Green 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, in Murrell Green and everywhere else we cover.

Questions from Murrell Green
Is Murrell Green in your area for external mastic?
Yes. We work across London and the South East, and Murrell Green is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Is Murrell Green within the area you cover?
Yes. Murrell Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Can you reach joints on upper floors?
It depends on the building. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.
Will the new joint stand out?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant isn’t too deep.
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.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep movement joints as flexible joints, not mortar
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
- Ask before painting over external sealant
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Murrell Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

What else we do in Murrell Green
What external mastic looks like in Murrell Green
Historic houses like Stratfield Saye House (about 4.9 miles north-west) are a reminder that the area around Murrell Green 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.
If you let a flat or house near Winchfield station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Hook Junior School, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as St John the Evangelist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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.
