Shefford Woodlands External Mastic
Our applicators work in Shefford Woodlands on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
- Rain getting behind render or cladding at a joint
External mastic in Shefford Woodlands
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. If you’re dealing with moss and dirt in joints with no sealant left and panel joints letting water in, we can help.
Older homes in small places like Shefford Woodlands may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes anything from a few hours to several days, depending on the building. In a small place like Shefford Woodlands, access is usually 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Move anything stored near the joints

Related advice
Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Where a wall is exposed, as many are in small places like Shefford Woodlands, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.

Walls and rooflines in Shefford Woodlands
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Stephen include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

What we are called out for in Shefford Woodlands
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Common reasons people contact us include:
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
If you let a flat or house near Hungerford station, outside joints that have cracked can let damp into a rental, so check them between lets.

What affects the quote in Shefford Woodlands
We don’t publish a price list. The quote depends on:
- How many areas need sealing
- How easy the joints are to reach
- The product the joint needs
- The amount of work
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Roughly how big the job is
- Whether it has been sealed before
- The type of property
- The address or postcode of the job
There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or drop us an email.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
- Deal with leaking gutters that soak the joints below
- Keep high-pressure jets off the joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Different surfaces, different methods
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Shefford Woodlands questions
Do you work for landlords with property near Hungerford station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover Shefford Woodlands for external mastic?
Yes. We work across London and the South East, and Shefford Woodlands is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
How long does the job take?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer.
Do you have insurance?
Yes. We’re fully insured.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move, and it should be sealed with a flexible sealant.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
