External mastic in Monkton
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on brickwork movement joints, concrete & block and façade panels, and people most often call us about joints pointed up with cement by mistake and damp patches traced to an open external joint.
External sealant needs dry, clean surfaces, so work around Monkton is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, large or small.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Looking after it afterwards
After the cure time, these simple habits help:
- Avoid pressure-washing directly into sealant joints
- Keep water from gutters off the wall
- Leave the joints unpainted unless we’ve said otherwise
- Walk round the building once a year and look at the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Outside joints around Monkton
Historic houses like Quex Park (about 2.6 miles north-east) are a reminder that the area around Monkton has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Minster station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Church of Saint Mary Magdalene, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Monkton Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
What affects the cost of external mastic
We quote each job individually. These are the things that affect it:
- The size of the job
- Any working-time requirements on site
- The product the joint needs
- Whether there’s mould to deal with
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.
What we need to know
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- If someone has resealed it before
- The address or postcode of the job
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or drop us an email.
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Monkton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:

- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
