External mastic for homes and businesses in Kingswood
For buildings in Kingswood, 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. We work on copings & trims, concrete & block and brickwork movement joints, and the jobs we see most are leaking joints around cladding and façade panels and hard, crazed mastic that has stopped moving.
Around Kingswood, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
Each job carries a 12-month guarantee, large or small.

Why act early in Kingswood
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Kingswood, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

Walls and rooflines in Kingswood
Historic houses like Leeds Castle (about 1.5 miles north) are a reminder that the area around Kingswood has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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 look after a building such as Kingswood Primary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Harrietsham station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Kingswood Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.
What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building for a typical job. In a small place like Kingswood, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Let us know about parking restrictions

Advice
Your questions about external mastic in Kingswood
Will you come out to Kingswood?
Yes. Kingswood is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Kingswood in your area for external mastic?
Yes. Our work covers London and the South East, and Kingswood is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What is backing rod for?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.

Honest limits
We will always be straight with you, so here’s what sealant can’t fix:
