External mastic for homes and businesses in St Margaret's Hope
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. If you are dealing with failed seals between different materials and sealant pulling away from one side of the joint, we can put it right.
Outside joints can only be sealed when they’re dry, so work in St Margaret's Hope depends on the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Your job is guaranteed for a year, as with all our work.

What sealant work cannot fix
We will not take on work that will not last, so these are the limits:
- Damp that isn’t coming from the joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.

Walls and rooflines in St Margaret's Hope
St Margaret's Hope is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Whether the job is in St Margaret's Hope itself or nearby, the right material for each joint matters as much as a neat finish.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Wash walls gently around the sealant
- Tell anyone working on the walls about the movement joints
- Don’t let climbing plants root in the sealant
- Leave the joints unpainted unless we’ve said otherwise
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
What affects the cost of external mastic
We do not publish a price list. What we look at:
- How much old sealant there is and how hard it is to remove
- The amount of work
- Mould in or behind the old joints
- The type of sealant required
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height

Do you need external mastic in St Margaret's Hope?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Common reasons people contact us include:
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
- Joints pointed up with cement by mistake
Around St Margaret's Hope, as everywhere, external mastic is only as good as the preparation behind it.

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
St Margaret's Hope questions
Do you cover St Margaret's Hope for external mastic?
Yes, St Margaret's Hope is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Does living near the coast affect external mastic in St Margaret's Hope?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
How do I get a quote for external mastic in St Margaret's Hope?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
Is there a guarantee?
Yes. Every job comes with our one-year guarantee.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across the Orkney Islands.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

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.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. Somewhere like St Margaret's Hope may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
