Maldon External Mastic
Our applicators work in Maldon on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Moss and dirt in joints with no sealant left
- Leaking joints around cladding and façade panels
- Failed seals between different materials
External mastic in Maldon
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you are dealing with cracked joints where brick meets render or frames and leaking joints around cladding and façade panels, we can help, whatever the surface.
In a town like Maldon, older houses with traditional gutters sit alongside newer estates with uPVC rooflines and rendered walls. All of those joints move, so they need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you are covered after we have gone.
Why it’s worth doing now in Maldon
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Black mould and gaps in sealant don’t fix themselves, and in a busy home in Maldon they get worse with every use. Now is the easy time to put it right.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Why book with us
- Any old sealant cut out fully, not covered over
- White, clear, grey or another colour, product permitting

Signs you need external mastic in Maldon
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
- Sealant pulling away from one side of the joint
Homes close to Church of St Mary include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Walls and rooflines in Maldon
Maldon is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
Managing a site like Maldon Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Parking in a town like Maldon is generally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules

Advice
Your questions about external mastic in Maldon
Is there a guarantee on external mastic in Maldon?
All our work, in Maldon and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is external mastic in a coastal place like Maldon any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What affects the quote in Maldon
Every job gets its own quote. This is what makes a difference:
- The number and length of the joints
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- The type of sealant required
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
When you contact us, these details help:
- A few photos by email, if you can
- The type of property
- The rough size of the job

What else we do in Maldon
How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
What we cannot put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that’s more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
What we seal
- Façade panels
- Render & cladding joints
- Concrete & block
- Copings & trims
- Joints between brick and frames
- Brickwork movement joints
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Never let anyone fill a movement joint with mortar
- Act on the first splits you see
- Do not let climbing plants root in the sealant
- Keep high-pressure jets off the joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
