External mastic for homes and businesses in Gatehead
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. We are often asked to deal with panel joints letting water in and damp patches traced to an open external joint, on façade panels, copings & trims and joints between brick and frames.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
You get a 12-month guarantee, the same in Gatehead as everywhere else we work.

Gatehead questions
Is Gatehead in your area for external mastic?

Is Gatehead within the area you cover?
Yes, Gatehead is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
What is a movement joint?
Walls move with heat, cold and moisture, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it doesn’t stand out.

What else we do in Gatehead
What happens if it’s left?
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 a place like Gatehead, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Do you need external mastic in Gatehead?
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
Rented homes near Kilmarnock station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before booking
- What product goes in the joint
- What preparation is included
- Whether they’re fully insured
- Whether they seal over old material or remove it
What external mastic looks like in Gatehead
The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. With historic houses such as Girgenti House (about 4.8 miles north) nearby, there’s older building stock in the area around Gatehead as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Grange Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Girgenti House, about 4.8 miles north, is one of the historic houses in the wider area around Gatehead.
