External & façade joints in Lea Bridge, Greater London
Sealing brickwork movement joints, render, cladding and façade joints for Lea Bridge, backed by a 12-month guarantee. Call for a quick quote.
- Joints pointed up with cement by mistake
- Joints with sealant missing in places
- Moss and dirt in joints with no sealant left
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep soil, plants and ivy away from the joints
- Keep high-pressure jets off the joints
- Make sure movement joints aren’t pointed over
- Ask before painting over external sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
About our external mastic in Lea Bridge
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you have movement joints filled with mortar instead of sealant and weeds or debris growing in open joints, we can help.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Lea Bridge, it’s worth checking who is responsible for the outside before booking.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Lea Bridge buildings and the weather
With historic houses such as Sutton House (about 1 mile south) nearby, there’s older building stock in the area around Lea Bridge as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking.
In the older streets around St Matthew, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Clapton station, split movement joints are easy to miss on a rental until damp shows inside. As a London address, Lea Bridge can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

The process
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours to a few days, depending on the length of joint and the access. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Mention any tricky access

Advice
What we can’t put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Damp that isn’t coming from the joint
- Movement that’s more than a sealant joint can take
- Cracking across the wall rather than at a joint
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
- Copings & trims
- Render & cladding joints
- Concrete & block
What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and helps it last.
Why it’s worth doing now in Lea Bridge
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Lea Bridge.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Lea Bridge questions
I let a flat near Clapton station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Is Lea Bridge in your area for external mastic?
Yes, Lea Bridge is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
How long does external mastic take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including the preparation. We’ll confirm how long when we quote.
Why do you put foam in the joint first?
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.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
How much does external mastic cost in Lea Bridge?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
