External Mastic in Dury
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Dury. Fully insured, ARBOMaster approved and guaranteed for a year.
- Failed sealant between panels on a façade
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Around Dury, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.

External mastic for homes and businesses in Dury
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you are dealing with sealant that has lost its bond to the brick or render and failed seals between different materials, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Dury depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
There’s a 12-month guarantee on every job.

What we are called out for in Dury
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Any of these means the joints need attention:
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
- Gaps where render, brick and frames meet
- Moss and dirt in joints with no sealant left
Around Dury, as everywhere, external mastic is only as good as the preparation behind it.

How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- The size of the job
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Asking for a quote
When you contact us, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- If someone has resealed it before
Need a quote? Please email us at info@mrmastic.co.uk with a few details. You will know what we plan to do, and what it will cost, before any work begins.
When something else is needed
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.

We also work for property managers and facilities teams in Dury and across the Shetland Islands. We can quote a run of properties together, and we are fully insured.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Tell anyone working on the walls about the movement joints
- Check the sealant is paintable before painting near it
- Fix overflowing gutters above sealed joints
- Never let anyone fill a movement joint with mortar
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.

Your questions about external mastic in Dury
Is external mastic in a coastal place like Dury any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you cover smaller places like Dury?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Will the new joint stand out?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
Are you insured?
Yes. We are fully insured.
Do you guarantee your work?
Yes. All our work carries our 12-month guarantee.
What happens on the day
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for a handful of joints, longer for a whole elevation. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- Clear items away from the joints we are working on

Outside joints around Dury
Dury is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Island weather, with its wind and salt spray, is tough on movement joints and outside wall joints.
Whether the job is in Dury itself or nearby, the right material for each joint matters as much as a neat finish.
