External mastic in Castle Hedingham: local notes
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 Hedingham Castle (about 0.2 miles north-east) are a reminder that the area around Castle Hedingham has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of St Nicholas include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Castle Hedingham is about 4 miles north-west of Halstead, in Essex. Jobs in Castle Hedingham get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee.

External mastic in Castle Hedingham
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. If you have failed sealant between panels on a façade and damp patches traced to an open external joint, we can put it right, whatever the surface.
Somewhere as small as Castle Hedingham, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Common problems we fix in Castle Hedingham
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
The problems people usually mention when they call are:
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
- Plants rooting in failed movement joints
Managing a site like de Vere Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- What the quote includes, VAT included or not
- How hidden problems are handled
- Whether you can choose the colour
- Whether all the old sealant comes out first
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Castle Hedingham, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
Getting ready for the visit
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions

Advice
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Loose or hollow render, which needs re-rendering
- Damp that is not coming from the joint
- Walls that need new movement joints cut into them
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
Where we work in Castle Hedingham
- Façade panels
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
- Joints between brick and frames
- Copings & trims
Different surfaces, different methods
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before the bead.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Castle Hedingham: your questions answered
Will you come out to Castle Hedingham?
Yes, Castle Hedingham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is external mastic in Castle Hedingham guaranteed?
All our work, in Castle Hedingham and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you have insurance?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Do you work at height?
It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep movement joints as flexible joints, not mortar
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
- Wash walls gently around the sealant
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Leave it or put it right?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way. In a small place like Castle Hedingham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
