- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take

External mastic for homes and businesses in Bolter End
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you have panel joints letting water in and joints with sealant missing in places, we can help, whatever the surface.
In a village or hamlet like Bolter End, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
There’s a 12-month guarantee on every job.

Bolter End questions
Is Bolter End within the area you cover?
Yes, Bolter End is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Bolter End for external mastic?
Yes. We work across London and the South East, and Bolter End is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
How long does the job take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
For landlords and businesses
Landlords and agents in Bolter End can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
When to call us in Bolter End
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Movement joints filled with mortar instead of sealant
- Joints where the bead has come unstuck
- Water getting into walls through failed joints
In the older streets around Church of the Holy Trinity, an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Act on the first splits you see
- Leave the joints unpainted unless we have said otherwise
- Point out the joints to other trades
- Look over the joints every year, ideally after winter
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
The process
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building for a typical job. Somewhere as small as Bolter End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Bolter End buildings and the weather
Historic houses like West Wycombe Park House (about 2.2 miles north-east) are a reminder that the area around Bolter End 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. 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.
Letting a property close to Saunderton station? Then split movement joints are easy to miss on a rental until damp shows inside. Schools such as Lane End Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Why act early in Bolter End
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. Around Bolter End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
