What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Lurgashall, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Mention if the joints have been sealed before

Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. If you are dealing with leaking joints around cladding and façade panels and failed seals between different materials, we can help.
Around Lurgashall, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

When it is not the sealant
A few problems are outside what sealant work can do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
- Walls that need new movement joints cut into them
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
- Copings & trims
- Façade panels
Different surfaces, different methods
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod.

What happens if it’s left?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Lurgashall can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

External mastic in Lurgashall: local notes
With historic houses such as Petworth House (about 3.9 miles south-east) nearby, there’s older building stock in the area around Lurgashall as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Haslemere station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Should I try it myself 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, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

When to call us in Lurgashall
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Signs it’s time to call us include:
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
- Joints pointed up with cement by mistake
For an older house near a landmark such as The Parish Church of St Lawrence, older walls, gutters and the joints where extensions meet them need a flexible sealant.

FAQs for Lurgashall
Do you work for landlords with property near Haslemere station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Can you do external mastic in Lurgashall?
Yes. We work across London and the South East, and Lurgashall is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
How do you reach high-level joints?
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.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
