Common questions in Langrish
Will you come out to Langrish?
Yes. Langrish is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Petersfield station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
External mastic in Langrish
For buildings in Langrish, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on render & cladding joints, copings & trims and brickwork movement joints, and people most often call us about moss and dirt in joints with no sealant left and gaps where render, brick and frames meet.
In a village or hamlet like Langrish, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
There’s a 12-month guarantee on every job, large or small.

How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- Which sealant suits the joint
- The size of the job
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

What else we do in Langrish
Why it’s worth doing now in Langrish
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Langrish, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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 email us and we will talk you through it.

How the job changes by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Langrish, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
Ask for a quote
Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand.
Related advice
Do you need external mastic in Langrish?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
- Failed seals between different materials
- Movement joints filled with mortar instead of sealant
If you live in an older home near Church of St John the Evangelist, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before you book
- How much experience the applicator has
- Whether all the old sealant comes out first
- Is VAT in the price?
- What the cure time is

For site and facilities teams at buildings such as Langrish Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Petersfield station, split movement joints are easy to miss on a rental until damp shows inside.
