Landlord and commercial work in Little Mill
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
External mastic in Little Mill, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. Typical jobs include rigid filler in a joint that should flex and failed seals between different materials, across concrete & block, façade panels and copings & trims.
Around Little Mill, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Look over the joints every year, ideally after winter
- Don’t let climbing plants root in the sealant
- Check the sealant is paintable before painting near it
- Act on the first splits you see
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
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?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Around Little Mill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Common problems we fix in Little Mill
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Movement joints filled with mortar instead of sealant
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
For an older house near a landmark such as Church of the Holy Trinity, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Questions from Little Mill
Can you help a landlord with a rental near Beltring station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Will you come out to Little Mill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What information do you need?
A short description and the location. We’ll ask anything else we need to know.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Façade panels
- Brickwork movement joints
- Render & cladding joints
- Joints between brick and frames
- Concrete & block
- Copings & trims
External mastic in Little Mill: local notes
With historic houses such as Old Soar Manor (about 4.4 miles north-west) nearby, there’s older building stock in the area around Little Mill 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Beltring station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like East Peckham Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
