About our external mastic in Lilliesleaf
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. Common call-outs are for joints pointed up with cement by mistake and hard, crazed mastic that has stopped moving, on render & cladding joints, joints between brick and frames and façade panels.
External sealant needs dry surfaces, so outdoor work around Lilliesleaf is planned around the weather. Let us know about access to every wall and roofline.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What the job involves on each surface
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.

Your questions about external mastic in Lilliesleaf
Is there a guarantee on external mastic in Lilliesleaf?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Lilliesleaf within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Outside joints around Lilliesleaf
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For jobs in and around Lilliesleaf, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are 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 doesn’t work out, we can still put it right.
What affects the quote in Lilliesleaf
We don’t publish a price list, because no two jobs are the same. What we look at:
- How much old sealant there is and how hard it is to remove
- How much there is to do
- How easy the joints are to reach
- The number of rooms or windows
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- Where the property is
- Access, such as stairs, a lift or height
- If someone has resealed it before
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
What we’re called out for in Lilliesleaf
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Most people get in touch when they notice one of these:
- Damp patches traced to an open external joint
- Failed seals between different materials
- Leaking joints around cladding and façade panels
- Movement joints filled with mortar instead of sealant
In and around Lilliesleaf, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

How the visit works
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work generally takes a few hours to a few days, depending on the length of joint and the access. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Tell us if parking is tricky

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Check external joints each spring
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
