External mastic in Lane End
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for rain getting behind render or cladding at a joint and gaps where render, brick and frames meet, on concrete & block, copings & trims and joints between brick and frames.
Outbuildings, garages and conservatories around homes in places like Lane End add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Ask before painting over external sealant
- Tell anyone working on the walls about the movement joints
- Make sure movement joints are not pointed over
- Keep high-pressure jets off the joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
Other services in Lane End
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. Around Lane End, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Common questions in Lane End
Will you come out to Lane End?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near High Wycombe station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
How do I get a quote for external mastic in Lane End?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Outside joints around Lane End
Historic houses like West Wycombe Park House (about 1.9 miles north-east) are a reminder that the area around Lane End has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Lane End Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of the Holy Trinity, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near High Wycombe station, outside joints that have cracked can let damp into a rental, so check them between lets.

How the job changes by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the building. In a smaller place like Lane End, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
