How the job changes by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one.
External mastic in Mud Row
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. We work on joints between brick and frames, concrete & block and render & cladding joints, and the jobs we see most are panel joints letting water in and joints pointed up with cement by mistake.
Around Mud Row, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
There’s a 12-month guarantee on every job, whatever its size.

FAQs for Mud Row
Do you cover smaller places like Mud Row?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is external mastic in a coastal place like Mud Row any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
How do I get a quote for external mastic in Mud Row?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How it works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. In a small place like Mud Row, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Let us know about parking restrictions

What else we do in Mud Row
Mud Row buildings and the weather
Mud Row is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Eastchurch Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.
Mud Row is about 3 miles east of Minster, in Kent. Whether you’re in the middle of Mud Row or further out, external mastic is available for homes and businesses alike. Our area takes in 922 places across Kent. Chelmsford is on our list too, about 28 miles from Mud Row.

Neighbouring places we cover for external mastic include Warden (1 mile east), Eastchurch (1 mile west), Bay View (1 mile south-east), Leysdown-on-Sea (2 miles south-east) and Minster (3 miles west).

Why act early in Mud Row
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. Around Mud Row, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Do not let climbing plants root in the sealant
- Act on the first splits you see
- Make sure movement joints aren’t pointed over
- Leave the joints unpainted unless we have said otherwise
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
When to call us in Mud Row
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
The most common problems we see are:
- Joints pointed up with cement by mistake
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
- Panel joints letting water in
For an older house near a landmark such as Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
