External mastic for homes and businesses in Tollesbury
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. Common call-outs are for hard, crazed mastic that has stopped moving and leaking joints around cladding and façade panels, on concrete & block, façade panels and joints between brick and frames.
Around Tollesbury, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee.

Leave it or put it right?
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Around Tollesbury, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Tollesbury questions
Is Tollesbury in your area for external mastic?
Yes. We work across London and the South East, and Tollesbury is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Is external mastic in a coastal place like Tollesbury any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Is it worth trying it myself?
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.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

What external mastic looks like in Tollesbury
Tollesbury is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Layer Marney Tower (about 4.8 miles north) are a reminder that the area around Tollesbury has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant.

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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Tollesbury, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
How to get a quote

When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
Joints and surfaces we work on
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Façade panels
- Concrete & block
- Brickwork movement joints
When to call us in Tollesbury
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
People usually contact us when they notice something like this:
- Moss and dirt in joints with no sealant left
- Panel joints letting water in
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
For site and facilities teams at buildings such as Tollesbury School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- How the joint is cleaned and prepared
- Whether VAT is included
- How long the guarantee is
- Which colour the sealant will be
