External Mastic in Spott
We cover Spott for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How we handle external mastic in Spott
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. Typical jobs include hard, crazed mastic that has stopped moving and moss and dirt in joints with no sealant left, across copings & trims, brickwork movement joints and joints between brick and frames.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Surface by 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.

Common questions in Spott
Will you come out to Spott?
Yes. Spott is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Spott affect outside sealant?
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.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
When will the joints need doing again?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins from the range available.
How do you reach high-level joints?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
What external mastic looks like in Spott
Spott is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In and around Spott, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints

Landlord and commercial work in Spott
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Have failed joints looked at early
- Point out the joints to other trades
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Common problems we fix in Spott
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
People generally contact us when they notice something like this:
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
- Water getting into walls through failed joints
For landlords with property near Dunbar station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
