DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
External mastic in Lilyvale
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint does not stand out. We work on joints between brick and frames, brickwork movement joints and copings & trims, and the jobs we see most are cracked joints where brick meets render or frames and brick movement joints where the sealant has split.
External sealant needs dry, clean surfaces, so work around Lilyvale is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Why deal with it now?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Lilyvale can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
Why us?
- A 12-month guarantee on all work
- Anti-fungal silicone where joints get wet
- We leave the area clean and tidy
- Any old sealant cut out fully, not covered over

Questions from Lilyvale
Is Lilyvale within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Westenhanger station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can you reach joints on upper floors?
It depends on the building. Send us photos and a rough idea of the height.
Are you insured?
Yes. We’re fully insured for every job we do.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
External mastic in Lilyvale: local notes
With historic houses such as Westenhanger Castle (about 2.7 miles south-east) nearby, there’s older building stock in the area around Lilyvale as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
If you look after a building such as Smeeth Community Primary School, larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Westenhanger station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

When something else is needed
It helps to know what we cannot do too:
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Signs you need external mastic in Lilyvale
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Keep an eye out for any of the following:
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
- Sealant pulling away from one side of the joint
In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- Whether the sealant suits the joint
- What insurance they hold
- Whether all the old sealant comes out first
- How much experience the applicator has
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Act on the first splits you see
- Leave the joints unpainted unless we’ve said otherwise
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job.

- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs 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
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
