External & façade joints in Langley, Hampshire
We cover Langley for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Rain getting behind render or cladding at a joint
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Act on the first splits you see
- Clear growth from the base of walls and joints
- Wash walls gently around the sealant
- Keep water from gutters off the wall
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
External mastic in Langley
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. Typical jobs include gaps where render, brick and frames meet and sealant pulling away from one side of the joint, across concrete & block, brickwork movement joints and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Langley is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
You get a 12-month guarantee, the same in Langley as everywhere else we work.

Questions from Langley
Will you come out to Langley?
Yes, smaller places are covered as well as towns. 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 Hamble station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Langley and across Hampshire. We can quote a run of properties together, and we’re fully insured for the work.
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
What we cannot put right
Sealant is not the answer to every problem, and we will tell you before any work starts. It won’t solve:
- Rising or penetrating damp from elsewhere in the wall
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.
Surfaces we seal
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Concrete & block
- Façade panels
Quotes for external mastic in Langley
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Any mould that needs treating
- The type of sealant required
- Access and height
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- What’s wrong with the joints now
- The type of property
- Any previous sealing or DIY work
- Any access issues, like height or stairs
Need a quote? Please call 0345 464 0079 or drop us an email with a few details. You will know what we plan to do, and what it will cost, before any work begins.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. In a small place like Langley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit

Related advice
Do you need external mastic in Langley?
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall.
The problems people generally mention when they call include:
- Panel joints letting water in
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Plants rooting in failed movement joints
Homes close to St Francis include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Langley buildings and the weather
Langley is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Beaulieu Palace House (about 3.5 miles west) are a reminder that the area around Langley has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Hamble station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Blackfield Primary School, larger buildings have long runs of movement joint that eventually need resealing.
