About our external mastic in Lamarsh
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. We work on copings & trims, render & cladding joints and brickwork movement joints, and people most often call us about damp patches traced to an open external joint and joints with sealant missing in places.
In a village or hamlet like Lamarsh, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Surface by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Why act early in Lamarsh
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Lamarsh, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

What should I tell you?
Tell us what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
How long does external mastic take?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we will say how long yours will take.
When something else is needed
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. It will not solve:
- Cracks in the bricks or render themselves, away from the joints
- Damp that isn’t coming from the joint
- Subsidence or other structural problems
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Lamarsh, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Mention any tricky access

Advice
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Lamarsh buildings and the weather
With historic houses such as Gainsborough's House (about 3.7 miles north) nearby, there’s older building stock in the area around Lamarsh as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Bures station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of the Holy Innocents, older walls, gutters and the joints where extensions meet them need a flexible sealant.
