About our external mastic in Hardwick
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. We work on brickwork movement joints, copings & trims and joints between brick and frames, and common reasons people get in touch are sealant that has lost its bond to the brick or render and failed sealant between panels on a façade.
Older homes in small places like Hardwick may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Questions from Hardwick
Do you cover Hardwick for external mastic?
Yes. We work across London and the South East, and Hardwick is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Bicester North station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Can you seal joints between render and window frames?
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.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. We’ll reseal it with a flexible sealant.
How long does external mastic take?
That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll tell you when we quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
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.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check the sealant is paintable before painting near it
- Get split or bare joints resealed while the damage is small
- Do not let climbing plants root in the sealant
- Look over the joints every year, ideally after winter
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Hardwick needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.

Outside joints around Hardwick
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Bicester North station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

- Render that’s blown, hollow or coming away
- Cracking across the wall rather than at a joint

Surface by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
