How we handle external mastic in Stonehaven
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. We work on joints between brick and frames, façade panels and copings & trims, and people most often call us about joints with sealant missing in places and panel joints letting water in.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
Each job carries a 12-month guarantee.

Is Stonehaven within the area you cover?

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 that we can handle for you.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never let anyone fill a movement joint with mortar
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
- Clear growth from the base of walls and joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Why act early in Stonehaven
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. In an older home around Stonehaven, damp from a failed joint can get into timber and plaster.
Doing several joints on one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
External mastic in Stonehaven: local notes
Stonehaven 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. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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 Fetteresso Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Stonehaven station, outside joints that have cracked can let damp into a rental, so check them between lets.

Signs you need external mastic in Stonehaven
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
People normally contact us when they notice one of these:
- Joints with sealant missing in places
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
- Hard, crazed mastic that has stopped moving
Schools such as Mackie Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
