About our external mastic in Molash
For buildings in Molash, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We are often asked to deal with joints pointed up with cement by mistake and weathered mastic that no longer stretches, across copings & trims, brickwork movement joints and joints between brick and frames.
Around Molash, 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.
Each job carries a 12-month guarantee, whatever its size.

How we quote for external mastic
Your quote is based on your job. We take into account:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The number of rooms or windows
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
Helping us quote
Photos help, but a description is a good start. Please mention:
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
If you are in Molash and need external mastic, call 0345 464 0079 or email us. Tell us what the problem is and where, and we’ll agree the price before any work begins.

What else we do in Molash
Looking after it afterwards
Aftercare is simple:
- Don’t let climbing plants root in the sealant
- Make sure movement joints are not pointed over
- Wash walls gently around the sealant
- Fix overflowing gutters above sealed joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Common questions in Molash
Do you cover Molash for external mastic?
Yes. We work across London and the South East, and Molash is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is Molash within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How much does external mastic cost in Molash?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Concrete & block
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
Common problems we fix in Molash
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Most people get in touch after spotting something like this:
- Rigid filler in a joint that should flex
- Plants rooting in failed movement joints
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
For landlords with property near Wye station, outside joints that have cracked can let damp into a rental, so check them between lets.

Molash buildings and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Belmont House and Gardens (about 3.8 miles north-west) nearby, there’s older building stock in the area around Molash 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.
If you live in an older home near Church of St Peter, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Surface by surface
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best in all weathers.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Molash, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Mention any parking rules near the property
