External Mastic in Wivelsfield
Problem with your movement joints in Wivelsfield? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.

- Water getting into walls through failed joints
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Joints between brick and frames
- Façade panels
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
- Copings & trims
External mastic in Wivelsfield, done properly
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include hard, crazed mastic that has stopped moving and rigid filler in a joint that should flex, across joints between brick and frames, concrete & block and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Wivelsfield is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All our work is covered by our 12-month guarantee, wherever you are in West Sussex.

Questions from Wivelsfield
Is Wivelsfield within the area you cover?
Yes, Wivelsfield is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Wivelsfield station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Are you insured?
Yes, we’re fully insured.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.

What else we do in Wivelsfield
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What happens if it’s left?
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. Older cottages and farmhouses around Wivelsfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

- More than 20 years in sealant work
- Colour agreed with you before we start

With historic houses such as Ockenden Manor (about 3.6 miles north-west) nearby, there’s older building stock in the area around Wivelsfield as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Signs you need external mastic in Wivelsfield
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
People usually contact us after spotting one of these:
- Damp patches traced to an open external joint
- Joints pointed up with cement by mistake
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
For site and facilities teams at buildings such as Wivelsfield Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Aftercare tips
After the cure time, these simple habits help:
- Fix overflowing gutters above sealed joints
- Make sure movement joints are not pointed over
- Clear growth from the base of walls and joints
- Show decorators and builders where the movement joints are
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
