What affects the quote in Bicknacre
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The number of rooms or windows
- The number and length of the joints
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before any work starts.

How we handle external mastic in Bicknacre
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall. We work on copings & trims, brickwork movement joints and façade panels, and people most often call us about gaps where render, brick and frames meet and movement joints with cracked, split or missing sealant.
Older homes in small places like Bicknacre may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Big or small, it’s backed by our 12-month guarantee in Bicknacre and across Essex.

External mastic in Bicknacre: local notes
Historic houses like Danbury Place (about 2 miles north-west) are a reminder that the area around Bicknacre has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as St Andrew's, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Priory Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
Bicknacre is about 5 miles south-west of Maldon, in Essex. Jobs in Bicknacre get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Our Essex coverage runs to 644 places, Bicknacre among them.

What’s near Bicknacre

Common problems we fix in Bicknacre
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
If you can see any of these, it’s time to have the joints looked at:
- Movement joints filled with mortar instead of sealant
- Plants rooting in failed movement joints
- Panel joints letting water in
- Rain getting behind render or cladding at a joint
For landlords with property near South Woodham Ferrers station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- How the colour is chosen

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. Somewhere like Bicknacre needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs 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.

Bicknacre questions
Is Bicknacre within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do external mastic in Bicknacre?
Yes, Bicknacre is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
What should I tell you?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
Why act early in Bicknacre
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Where a wall is exposed, as many are in small places like Bicknacre, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How the job changes by surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
