Worth questions
I let a flat near Sandwich station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Does the coastal weather in Worth affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
What is a movement joint?
A vertical gap in a long brick wall is normally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
When is the sealant fully cured?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
About our external mastic in Worth
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Common call-outs are for weathered mastic that no longer stretches and failed seals between different materials, across façade panels, joints between brick and frames and brickwork movement joints.
Around Worth, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Outside joints around Worth
Worth is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is 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.
Managing a site like Worth Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Church of St Peter and St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

When it is not the sealant
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Cracking across the wall rather than at a joint
- Walls that need new movement joints cut into them
- Render that’s blown, hollow or coming away
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Joints between brick and frames
- Copings & trims
- Concrete & block
- Brickwork movement joints
- Render & cladding joints
- Façade panels
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Leave it or put it right?
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 damage spreads beyond the joint. Older cottages and farmhouses around Worth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

What we are called out for in Worth
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Any of these means the joints need attention:
- Weathered mastic that no longer stretches
- Movement joints filled with mortar instead of sealant
- Moss and dirt in joints with no sealant left
- Sealant that has lost its bond to the brick or render
Letting a property close to Sandwich station? Then split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- Is VAT in the price?
- How the colour is chosen
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Worth needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
