What we’re called out for in Wilsley Green
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
Most people get in touch after spotting something like this:
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
- Failed sealant between panels on a façade
- Failed seals between different materials
Homes close to Church of St Dunstan include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

External mastic in Wilsley Green
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint doesn’t stand out. We work on render & cladding joints, brickwork movement joints and joints between brick and frames, and people most often call us about hard, crazed mastic that has stopped moving and joints where the bead has come unstuck.
External sealant needs dry, clean surfaces, so work around Wilsley Green is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
We stand behind the work with a 12-month guarantee.

External mastic in Wilsley Green: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Staplehurst station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Cranbrook Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Questions from Wilsley Green
Can you do external mastic in Wilsley Green?
Yes. We work across London and the South East, and Wilsley Green is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Wilsley Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Is it worth trying 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.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the building from start to finish. Somewhere as small as Wilsley Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Mention any sign-in or site rules at work premises

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Landlord and commercial work in Wilsley Green
We also work for property managers and facilities teams. Several sites can go on one quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a small place like Wilsley Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.
