Crockhurst Street External Mastic
Professional external mastic in and around Crockhurst Street, with old sealant always removed completely and a 12-month guarantee.
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
- Sealant that has lost its bond to the brick or render
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How we handle external mastic in Crockhurst Street
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on joints between brick and frames, façade panels and copings & trims, and the jobs we see most are failed seals between different materials and weathered mastic that no longer stretches.
Outside joints can only be sealed when they’re dry, so work in Crockhurst Street is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months, in Crockhurst Street and everywhere else we cover.

FAQs for Crockhurst Street
Can you do external mastic in Crockhurst Street?
Yes, Crockhurst Street is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Will you come out to Crockhurst Street?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask before painting over external sealant
- Don’t let climbing plants root in the sealant
- Show decorators and builders where the movement joints are
- Never let anyone fill a movement joint with mortar
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Movement that’s more than a sealant joint can take
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

Crockhurst Street buildings and the weather
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.
In the older streets around Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Tonbridge station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Capel Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Around Crockhurst Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
