Dailly External Mastic
External mastic across Dailly and nearby, with old sealant always removed completely and a 12-month guarantee.
- Movement joints with cracked, split or missing sealant
- Plants rooting in failed movement joints
- Hard, crazed mastic that has stopped moving
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
External mastic in Dailly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we do not skip that step. We are often asked to deal with old sealant gone brittle and cracked and movement joints with cracked, split or missing sealant, across brickwork movement joints, render & cladding joints and concrete & block.
External sealant needs dry surfaces, so outdoor work around Dailly is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Whatever the size of the job, you get the same one-year guarantee.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Tell anyone working on the walls about the movement joints
- Look over the joints every year, ideally after winter
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
What external mastic looks like in Dailly
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Dailly is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
Around Dailly, as everywhere, external mastic is only as good as the preparation behind it.

Surface by surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use or an approved alternative. Send us any details you have about the façade.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. Around Dailly, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention any tricky access
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

Dailly questions
Will you come out to Dailly?
Yes. Dailly is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is there a guarantee on external mastic in Dailly?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
How much does external mastic cost in Dailly?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Honest limits
We will always be straight with you, so here’s what new sealant won’t do:
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Joints and surfaces we work on
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
- Copings & trims
Common problems we fix in Dailly
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Old sealant gone brittle and cracked
- Leaking joints around cladding and façade panels
- Gaps where render, brick and frames meet
- Rain getting behind render or cladding at a joint
For jobs in and around Dailly, choosing the right material for each joint is as important as a tidy finish.
