Bullsmoor buildings and the weather
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 Forty Hall (about 1 mile south-west) are a reminder that the area around Bullsmoor 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.
As a London address, Bullsmoor can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as St George's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Bullsmoor is about 2 miles north-east of Enfield, in Greater London. Bullsmoor gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 786 towns and villages across Greater London.

Whether your property is on Capel Road, Unity Road and Kempe Road or anywhere close by, our applicators can take on the job.

How we handle external mastic in Bullsmoor
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. If you’re dealing with sealant that has lost its bond to the brick or render and rain getting behind render or cladding at a joint, we can put it right, whatever the surface. Mr Mastic is a mastic company, not a general handyman, which means external mastic in Bullsmoor is done by people who seal joints every day.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Bullsmoor, tell us how high the joints are and how to reach the back of the building.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Common questions in Bullsmoor
Can you help a landlord with a rental near Turkey Street station?
Yes. We work for letting agents and landlords as well as householders. You can phone 07833 053749 or email us with the details for a clear quote.
Do you cover Bullsmoor for external mastic?
Yes. Our work covers London and the South East, and Bullsmoor is part of that. You can call 07833 053749 or drop us an email and let us know what needs doing.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
How long will you be here?
A typical job takes anything from a few hours to several days, depending on the building, including preparation and clearing up. Your quote will say how long we expect yours to take.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What happens on the day
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. In Bullsmoor, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many areas need sealing
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.
Helping us quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- Where the property is
- The rough size of the job
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
What we are called out for in Bullsmoor
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
People normally contact us when they notice something like this:
- Sealant pulling away from one side of the joint
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
- Rigid filler in a joint that should flex
Rented homes near Turkey Street station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Get split or bare joints resealed while the damage is small
- Check external joints each spring
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
