External Mastic in Enham Alamein
External mastic across Enham Alamein and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Plants rooting in failed movement joints
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
How we handle external mastic in Enham Alamein
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We are often asked to deal with old sealant gone brittle and cracked and joints with sealant missing in places, across copings & trims, brickwork movement joints and joints between brick and frames.
Around Enham Alamein, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
We stand behind the work with a 12-month guarantee.

Should I try it myself first?
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 fails, we can still redo it.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How the job changes by surface
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.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Enham Alamein: your questions answered
Is Enham Alamein within the area you cover?
Yes, Enham Alamein is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Enham Alamein in your area for external mastic?
Yes. We work across London and the South East, and Enham Alamein is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working and can lead to cracking. We’ll reseal it with a flexible sealant.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
How long does the job take?
A typical job takes a few hours to a few days, depending on the length of joint and the access. Your quote will say how long we expect yours to take.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels
- Movement that is more than a sealant joint can take
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Signs you need external mastic in Enham Alamein
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint.
Common reasons people contact us include:
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
- Gaps where render, brick and frames meet
For site and facilities teams at buildings such as Smannell and Enham Church of England (Aided) Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Act on the first splits you see
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
- Clear growth from the base of walls and joints
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.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
External mastic in Enham Alamein: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Saint George include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Andover station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere like Enham Alamein needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
