About our external mastic in Wormshill
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. Typical jobs include panel joints letting water in and sealant that has lost its bond to the brick or render, across concrete & block, brickwork movement joints and façade panels.
Older homes in small places like Wormshill may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How it works
Most of a good job is in the preparation, so that’s 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 Wormshill 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.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

External mastic in Wormshill: local notes
Historic houses like Leeds Castle (about 3.7 miles south-west) are a reminder that the area around Wormshill has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you let a flat or house near Harrietsham station, outside joints that have cracked can let damp into a rental, so check them between lets.
Wormshill is about 4 miles south-west of Sittingbourne, in Kent. Wormshill gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 922 towns and villages across Kent. We also work in Chelmsford, around 33 miles away.

What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Walls that need new movement joints cut into them
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
Joints and surfaces we work on
- Render & cladding joints

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Signs you need external mastic in Wormshill
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.
The problems people usually mention when they call are:
- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
- Failed seals between different materials
- Rigid filler in a joint that should flex
Homes close to St Giles include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Questions from Wormshill
Is Wormshill within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Wormshill in your area for external mastic?
Yes. Our work covers London and the South East, and Wormshill is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
How long before the joint can be used?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Are you insured?
Yes. We’re fully insured.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll give you a better idea when we quote.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
Why deal with it now?
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Wormshill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
