External & façade joints in Pitshanger, Greater London
We cover Pitshanger for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
- Joints where the bead has come unstuck
How we handle external mastic in Pitshanger
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. Common call-outs are for leaking joints around cladding and façade panels and sealant pulling away from one side of the joint, across concrete & block, render & cladding joints and copings & trims.
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. For a flat in Pitshanger, check the lease for who looks after the outside.
Big or small, you get the same 12-month guarantee in Pitshanger and across Greater London.

Outside joints around Pitshanger
Historic houses like Pitzhanger Manor (about 1.1 miles south) are a reminder that the area around Pitshanger 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. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
If you look after a building such as North Ealing Primary School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Church of St Barnabas, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Your questions about external mastic in Pitshanger
Can you do external mastic in Pitshanger?
Yes, Pitshanger is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Is parking a problem for a job in Pitshanger?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Can I do it myself?
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 does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. In a London area like Pitshanger, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We look at every joint and agree a colour to suit the wall.
- 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

Related advice
Landlords, agents and businesses in Pitshanger
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too in Pitshanger and across Greater London. Several sites can be quoted together, and we’re fully insured.
Surface by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so the movement is taken up.
Common problems we fix in Pitshanger
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
It’s worth asking for a quote if you see:
- Rain getting behind render or cladding at a joint
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
As a London address, Pitshanger can be tricky for parking: let us know about parking bays, permits or a driveway.
