External mastic for homes and businesses in North Benfleet
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the line blends in. We work on render & cladding joints, façade panels and joints between brick and frames, and people most often call us about movement joints filled with mortar instead of sealant and sealant that has lost its bond to the brick or render.
Around North Benfleet, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee, large or small.

Questions from North Benfleet
I let a flat near Pitsea station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Can you do external mastic in North Benfleet?
Yes. We work across London and the South East, and North Benfleet is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
What is a movement joint?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces with primer where required.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Common problems we fix in North Benfleet
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
These are the problems we are asked about most:
- Joints with sealant missing in places
- Cracked joints where brick meets render or frames
- Rain getting behind render or cladding at a joint
- Plants rooting in failed movement joints
If you look after a building such as Montgomerie Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- Whether you can choose the colour
- Whether all the old sealant comes out first
- Whether VAT is included
- How the joint is cleaned and prepared
Surface by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. Somewhere as small as North Benfleet, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

What external mastic looks like in North Benfleet
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Pitsea station, split movement joints are easy to miss on a rental until damp shows inside.

Aftercare tips
Looking after new joints is easy:
- Keep movement joints as flexible joints, not mortar
- Check the sealant is paintable before painting near it
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
