About our external mastic in Flemings
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We work on copings & trims, joints between brick and frames and render & cladding joints, and common reasons people get in touch are sealant that has lost its bond to the brick or render and joints pointed up with cement by mistake.
Outside joints can only be sealed when they’re dry, so work in Flemings is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All our work is covered by a 12-month guarantee, wherever you are in Kent.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Cracked brickwork or render that needs a builder or plasterer
- Damp that isn’t coming from the joint
- Render that’s blown, hollow or coming away
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
What else we do in Flemings
The process
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the building from start to finish. For a village or hamlet like Flemings, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Flemings buildings and the weather
Historic houses like Goodnestone Park (about 2.7 miles south-west) are a reminder that the area around Flemings has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you live in an older home near Church of St Nicholas, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Ash Cartwright and Kelsey Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Flemings questions

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Yes, Flemings is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
How long does external mastic last?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
How long does the job take?
A typical job takes a few hours to a few days, depending on the length of joint and the access. We’ll confirm how long when we quote.
Why act early in Flemings
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. Around Flemings, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

What we’re called out for in Flemings
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
These are the problems we are asked about most:
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
- Sealant that has lost its bond to the brick or render
For landlords with property near Sandwich station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
