External mastic in Buckhurst Hill
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. If you’re dealing with joints where the bead has come unstuck and cracked joints where brick meets render or frames, we can help.
In and around Buckhurst Hill, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Check external joints each spring
- Ask before painting over external sealant
- Fix overflowing gutters above sealed joints
- Never let anyone fill a movement joint with mortar
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.

Why act early in Buckhurst Hill
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Homes in smaller places like Buckhurst Hill can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before work begins.

Your questions about external mastic in Buckhurst Hill
Is Buckhurst Hill within the area you cover?
Yes. Buckhurst Hill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Chingford station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is there a guarantee?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we will confirm the access.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Damp that is not coming from the joint
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Surfaces we seal
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
- Concrete & block
- Façade panels
Common problems we fix in Buckhurst Hill
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Signs it’s time to call us include:
- Leaking joints around cladding and façade panels
- Water getting into walls through failed joints
- Hard, crazed mastic that has stopped moving
- Joints pointed up with cement by mistake
Homes close to St Stephen's include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before you book
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
- How hidden problems are handled
- Who does the work, and how experienced they are
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Surface by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on the building from start to finish. For a job in Buckhurst Hill, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

External mastic in Buckhurst Hill: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Valentines Mansion (about 3.9 miles south) nearby, there’s older building stock in the area around Buckhurst Hill 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.
If you look after a building such as Buckhurst Hill Community Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Chingford station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
