External mastic for homes and businesses in Bundalloch
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We work on joints between brick and frames, brickwork movement joints and render & cladding joints, and the jobs we see most are rigid filler in a joint that should flex and sealant that has lost its bond to the brick or render.
External sealant needs dry surfaces, so outdoor work around Bundalloch is planned around the weather. Tell us how to reach each wall, gutter and roofline.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Common problems we fix in Bundalloch
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
It’s worth asking for a quote if you see:
- Hard, crazed mastic that has stopped moving
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
- Sealant that has lost its bond to the brick or render
Rented homes near Stromeferry station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Common questions in Bundalloch
Do you work for landlords with property near Stromeferry station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Does living near the coast affect external mastic in Bundalloch?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Why it’s worth doing now in Bundalloch
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together. In an older home around Bundalloch, damp from a failed joint can get into timber and plaster.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Outside joints around Bundalloch
Bundalloch 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. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Homes close to St Duthuc's Roman Catholic Chapel include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Bundalloch is in Highland. Bundalloch gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Bundalloch is one of 253 towns and villages in Highland where we work for external mastic.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Walk round the building once a year and look at the joints
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we have said otherwise
- Keep high-pressure jets off the joints
Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants are not designed to be painted.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access.

- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- 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.

- Let us know if you’ve seen damp or leaks
