About our external mastic in Lindford
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We work on façade panels, brickwork movement joints and concrete & block, and the jobs we see most are rain getting behind render or cladding at a joint and weeds or debris growing in open joints.
Around Lindford, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
There’s a 12-month guarantee on every job, large or small.

What external mastic looks like in Lindford
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.
For landlords with property near Liphook station, outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

Your questions about external mastic in Lindford
Do you work for landlords with property near Liphook station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Is Lindford within the area you cover?
Yes. Lindford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year.
Where are you based?
Mr Mastic is based in Crawley. We cover Lindford and the rest of Hampshire, along with the rest of our area.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

What else we do in Lindford
What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
- Render that’s blown, hollow or coming away
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.
What we seal
- Concrete & block
- Façade panels
- Copings & trims
- Brickwork movement joints
- Render & cladding joints
- Joints between brick and frames
Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Signs you need external mastic in Lindford
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
People usually contact us when they notice something like this:
- Sealant pulling away from one side of the joint
- Rain getting behind render or cladding at a joint
- Moss and dirt in joints with no sealant left
- Hard, crazed mastic that has stopped moving
Managing a site like Weyford Nursery and Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building. Parking around Lindford is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Advice
Looking after it afterwards
Looking after new joints is easy:
- Ask before painting over external sealant
- Avoid pressure-washing directly into sealant joints
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
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 work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.
