External mastic for homes and businesses in Ratcliff
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We work on brickwork movement joints, copings & trims and joints between brick and frames, and common reasons people get in touch are cracked joints where brick meets render or frames and old sealant gone brittle and cracked.
Modern London flats rely on sealed movement joints and cladding joints. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall.
There’s a 12-month guarantee on every job, large or small.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for a handful of joints, longer for a whole elevation. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Ratcliff. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, the joints are inspected and the access agreed.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed

Advice
External mastic in Ratcliff: local notes
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Marion Richardson Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Limehouse station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Can you do external mastic in Ratcliff?

Are you insured?

What should I tell you?
A short description and the location, plus pictures if you have them. If we need more, we’ll ask.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long does external mastic last?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Aftercare tips
So the new joints stay in good condition:
- Act on the first splits you see
- Leave the joints unpainted unless we have said otherwise
- Point out the joints to other trades
- Wash walls gently around the sealant
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Signs you need external mastic in Ratcliff
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
Keep an eye out for any of the following:
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
- Weeds or debris growing in open joints
- Sealant pulling away from one side of the joint
Ratcliff is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Different surfaces, different methods
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
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.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What sealant work can’t fix
New sealant can’t fix everything, and we will tell you before any work starts. Sealant will not put right:
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
