What sealant work can’t fix
In fairness, some problems need a different trade:
- Movement that is more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal

External mastic in New Deer, done properly
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. We work on joints between brick and frames, brickwork movement joints and render & cladding joints, and the jobs we see most are gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving.
In and around a place like New Deer, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep soil, plants and ivy away from the joints
- Make sure movement joints aren’t pointed over
- Look over the joints every year, ideally after winter
- Get split or bare joints resealed while the damage is small
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
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.
What the job involves on each surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
The process
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access. Outdoor work around New Deer depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

Questions from New Deer
Do you cover smaller places like New Deer?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do external mastic in New Deer?
Yes. Our work covers the whole of Scotland, and New Deer is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Are you insured?
Yes. Full insurance covers our work.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Walls and rooflines in New Deer
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
If you live in an older home near New Deer Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. In and around New Deer, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Should I try it myself 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, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a place like New Deer, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
