External mastic for homes and businesses in Stoke Row
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. We work on copings & trims, joints between brick and frames and brickwork movement joints, and common reasons people get in touch are damp patches traced to an open external joint and sealant that has lost its bond to the brick or render.
Around Stoke Row, 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.
Whatever the size of the job, you get the same 12-month guarantee.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Show decorators and builders where the movement joints are
- Avoid pressure-washing directly into sealant joints
- Ask before painting over external sealant
- Make sure movement joints are not pointed over
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- How many rooms, windows or areas are involved
- Any mould that needs treating

Your questions about external mastic in Stoke Row
Can you do external mastic in Stoke Row?
Yes, Stoke Row is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Will you come out to Stoke Row?
Yes, Stoke Row is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you guarantee your work?
Yes. All our work carries a 12-month guarantee.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Somewhere like Stoke Row needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Outside joints around Stoke Row
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. Historic houses like Greys Court (about 2.7 miles east) are a reminder that the area around Stoke Row 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.
If you look after a building such as Stoke Row Church of England School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of St John the Evangelist include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it.
