Oakthorpe Park External Mastic
Our applicators work in Oakthorpe Park on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
- Failed seals between different materials
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
Where we work in Oakthorpe Park
- Brickwork movement joints
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Façade panels
How we handle external mastic in Oakthorpe Park
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. If you are dealing with joints where the bead has come unstuck and weathered mastic that no longer stretches, we can put it right.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so one failed joint can cause damp for more than one household. In a converted house in Oakthorpe Park, it’s worth checking who is responsible for the outside before booking.
All of our work is guaranteed for twelve months, in Oakthorpe Park and everywhere else we cover.

What happens on the day
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. In Oakthorpe Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Send us any details you have about the façade.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Common problems we fix in Oakthorpe Park
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.
People generally contact us when they notice one of these:
- Joints with sealant missing in places
- Weeds or debris growing in open joints
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
As a London address, Oakthorpe Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Quotes for external mastic in Oakthorpe Park
Your quote is based on your job. We take into account:
- Whether there’s mould to deal with
- The number of rooms or windows
- The product the joint needs
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Where the property is
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Why act early in Oakthorpe Park
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Oakthorpe Park, the repair is bigger than a sealant job.
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

FAQs for Oakthorpe Park
Is parking an issue for external mastic in Oakthorpe Park?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I let a flat near Palmers Green station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What should I tell you?
Let us know what needs doing and where. We will ask anything else we need to know.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Do you work in Oakthorpe Park?
Yes, we do. Oakthorpe Park is part of the area we cover, and the service is the same as everywhere else.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.

What external mastic looks like in Oakthorpe Park
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Bruce Castle (about 1.7 miles south-east) nearby, there’s older building stock in the area around Oakthorpe Park as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like St Anne's Catholic High School for Girls? Then larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Palmers Green station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
