About our external mastic in Tottenham
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you are dealing with plants rooting in failed movement joints and movement joints with cracked, split or missing sealant, we can put it right.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Tottenham, it’s worth checking who is responsible for the outside before booking.
Big or small, you get the same 12-month guarantee.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel

- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.

External mastic in Tottenham: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Bruce Castle (about 0.3 miles west) are a reminder that the area around Tottenham 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 live in an older home near Church of St Mary the Virgin, old and new materials meet at the roofline and walls, which is where sealant earns its keep. As a London address, Tottenham can be tricky for parking: let us know about parking bays, permits or a driveway.
Tottenham is about 6 miles north-east of Marylebone, in Greater London. Jobs in Tottenham get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Tottenham is one of 764 places in Greater London we cover for external mastic. There’s also a page for London, roughly 7 miles from Tottenham.
Postcode districts we cover here for external mastic: N17, N15 and N18. Whether your property is on New Road, High Road and Reed Road or a nearby road, we can help. With the A10 close by, Tottenham is easy for our applicators to reach.

Within a short drive, we also cover London (7 miles south), City of Westminster (7 miles south-west), Marylebone (6 miles south-west), Kensington (9 miles south-west), St Pancras (5 miles south-west) and Shoreditch (5 miles south).

The countryside around Tottenham includes Highgate Hill and Railway Fields.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the sealant is paintable before painting near it
- Keep high-pressure jets off the joints
- Make sure movement joints are not pointed over
- Show decorators and builders where the movement joints are
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
What sealant work cannot fix
Sealant is not the answer to every problem, and we’ll tell you before any work starts. It won’t solve:
- Failed render or damaged cladding panels
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
Joints and surfaces we work on
- Render & cladding joints
- Copings & trims
- Concrete & block

Questions from Tottenham
I let a flat near Bruce Grove station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Is Tottenham in your area for external mastic?
Yes, Tottenham is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How long will you be here?
A typical job takes anything from a few hours to several days, depending on the building. We will confirm how long when we quote.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
What we are called out for in Tottenham
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Most people get in touch after spotting something like this:
- Movement joints filled with mortar instead of sealant
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Sealant pulling away from one side of the joint
For site and facilities teams at buildings such as The Mulberry Primary School, its movement joints, gutters and trims need looking after like any other building’s.
Before booking anyone
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
- Is VAT in the price?
- How long the guarantee is
