About our external mastic in Orchard Leigh
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. If you have water getting into walls through failed joints and brick movement joints where the sealant has split, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Orchard Leigh is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Surface by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Orchard Leigh, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts

Orchard Leigh questions
Do you cover smaller places like Orchard Leigh?
Yes, Orchard Leigh is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Berkhamsted station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so the joint doesn’t draw the eye.
Can new sealant go over the old?
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 I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Where do you work from?
We work from Crawley. Our applicators cover Orchard Leigh.
Can you reach joints on upper floors?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we’ll confirm the access.
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Around Orchard Leigh, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

Looking after it afterwards
After the cure time, these simple habits help:
- Leave the joints unpainted unless we have said otherwise
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.

When it isn’t the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Damp that isn’t coming from the joint
- Cracking across the wall rather than at a joint
- Adding movement joints to masonry that has none
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Outside joints around Orchard Leigh
Historic houses like Chenies Manor House (about 3.6 miles south-east) are a reminder that the area around Orchard Leigh 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. The South East is one of the drier parts of the UK, 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 Ley Hill School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Berkhamsted station? Then split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as St George's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
