External mastic for homes and businesses in Locheport
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. We are often asked to deal with joints with sealant missing in places and weathered mastic that no longer stretches, across render & cladding joints, joints between brick and frames and brickwork movement joints.
In and around a place like Locheport, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
The work is covered for a year after we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

External mastic in Locheport: local notes
Locheport is within about 1 mile of 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. On the islands, wind and salt spray are hard on outside sealant.
For jobs in and around Locheport, choosing the right material for each joint is as important as a tidy finish.

How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it before the bead.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Locheport depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires 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 parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
Getting a quote
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.
Related advice
Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Around Locheport, 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.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Loose or hollow render, which needs re-rendering
- Cracked brickwork or render that needs a builder or plasterer
- Damp that is not coming from the joint
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.

Common problems we fix in Locheport
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
People generally contact us when they notice something like this:
- Moss and dirt in joints with no sealant left
- Sealant pulling away from one side of the joint
- Gaps where render, brick and frames meet
- Weathered mastic that no longer stretches
In and around Locheport, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Check the sealant is paintable before painting near it
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
DIY sealant or a professional job?
If you’re 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 does not work out, we can still put it right.
The difference is mostly in the preparation and the 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.
