How the visit works
At the end, we look at the finished work together. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere as small as Burmarsh, 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.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

About our external mastic in Burmarsh
On houses, flats and commercial buildings across Burmarsh, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you’re dealing with brick movement joints where the sealant has split and damp patches traced to an open external joint, we can help.
Older homes in small places like Burmarsh may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What else we do in Burmarsh
FAQs for Burmarsh
Does the coastal weather in Burmarsh affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Do you cover smaller places like Burmarsh?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it does not stand out.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How long should I leave it?
Cure times vary by product. Before we leave, we will tell you the cure time.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working. We’ll reseal it with a flexible sealant.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in Burmarsh.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Damp that isn’t coming from the joint
- Movement that’s more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.
Surfaces we seal
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
- Façade panels
- Copings & trims
What we’re called out for in Burmarsh
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The most common problems we see are:
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
If you live in an older home near Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before you book
- What product goes in the joint
- Is VAT in the price?
- Is the old sealant removed completely?
- What guarantee comes with the work
Burmarsh buildings and the weather
Burmarsh is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Westenhanger Castle (about 3.5 miles north-east) nearby, there’s older building stock in the area around Burmarsh as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Westenhanger station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Burmarsh is about 4 miles south-west of Hythe, in Kent. Every kind of property in Burmarsh can book us for external mastic. Every job comes with our one-year guarantee.

If you’re just outside Burmarsh, we cover Postling Green (3 miles north-west), St Mary's Bay (3 miles south), Newchurch (3 miles west), St Mary in the Marsh (3 miles south-west) and Aldington (4 miles north-west).

Around Burmarsh
We work in homes and buildings around The Shepherd And Crook Public House and the streets around them. The nearest railway station is Westenhanger station, about 3.7 miles north-east. A little further out are Hythe Museum (4 miles east) and Lympne Castle (2 miles north-east).
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Avoid pressure-washing directly into sealant joints
- Do not let climbing plants root in the sealant
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Different surfaces, different methods
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.
Why act early in Burmarsh
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Burmarsh, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

- Any working-time requirements on site
- Which sealant suits the joint
Doing several joints on one visit usually makes better use of the time than several visits. We will give you a clear quote for the lot.
