What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Movement that is more than a sealant joint can take
- Failed render or damaged cladding panels
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

External mastic in Denstroude, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on render & cladding joints, copings & trims and joints between brick and frames, and common reasons people get in touch are weathered mastic that no longer stretches and failed seals between different materials.
Somewhere as small as Denstroude, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, it’s backed by our one-year guarantee.

How the job changes by surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before the bead.
What affects the cost of external mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- Access and height
- The number and length of the joints
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What external mastic looks like in Denstroude
Denstroude is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Denstroude, as everywhere, external mastic is only as good as the preparation behind it. Letting a property close to Whitstable station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
Denstroude is about 3 miles south of Whitstable, in Kent.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Somewhere as small as Denstroude, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

Related advice
Common questions in Denstroude
Does the coastal weather in Denstroude affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Denstroude?
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.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Clear growth from the base of walls and joints
- Leave the joints unpainted unless we have said otherwise
- Walk round the building once a year and look at the joints
- Keep movement joints as flexible joints, not mortar
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. In a small place like Denstroude, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
