How we handle external mastic in Chadwell St Mary
For buildings in Chadwell St Mary, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have moss and dirt in joints with no sealant left and rain getting behind render or cladding at a joint, we can help.
Around Chadwell St Mary, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
All our work comes with our one-year guarantee, wherever you are in Thurrock.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
- Do not let climbing plants root in the sealant
- Have failed joints looked at early
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

What else we do in Chadwell St Mary
Common problems we fix in Chadwell St Mary
Some movement joints have been pointed up with mortar. The joint can’t move, so the wall cracks somewhere else instead.
Any of these means the joints need attention:
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Rigid filler in a joint that should flex
- Panel joints letting water in
Homes close to Emmanuel Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Chadwell St Mary questions
Do you cover smaller places like Chadwell St Mary?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

How long does external mastic last?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
DIY versus a professional finish
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Outside joints around Chadwell St Mary
Chadwell St Mary is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Herringham Primary Academy? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near East Tilbury station, outside joints that have cracked can let damp into a rental, so check them between lets.

How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. A visit to Chadwell St Mary is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- 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.
Getting ready for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Related advice
Why act early in Chadwell St Mary
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Around Chadwell St Mary, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
