External & façade joints in Rucklers Lane, Hertfordshire
Movement joints in Rucklers Lane need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
What the job involves on each surface
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
How we handle external mastic in Rucklers Lane
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We work on concrete & block, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are brick movement joints where the sealant has split and rain getting behind render or cladding at a joint.
Somewhere as small as Rucklers Lane, homes and farm buildings often face open ground, 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.

Why act early in Rucklers Lane
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Rucklers Lane, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Your questions about external mastic in Rucklers Lane
Do you cover smaller places like Rucklers Lane?
Yes. Rucklers Lane 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 Apsley station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Rucklers Lane.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, large or small.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. Somewhere like Rucklers Lane needs a little journey planning: 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.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Mention if the joints have been sealed before

What external mastic looks like in Rucklers Lane
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like High Elms Manor (about 3.2 miles south-east) are a reminder that the area around Rucklers Lane has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Apsley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Kings Langley Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.
