Mansfield: your questions answered
Is Mansfield in your area for external mastic?
Yes. We work across all of Scotland, and Mansfield is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is Mansfield within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
How do I get a quote for external mastic in Mansfield?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall. If it has already been filled, we can generally cut it out and reseal it.
How we handle external mastic in Mansfield
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 in a matching colour. Typical jobs include joints pointed up with cement by mistake and panel joints letting water in, on copings & trims, joints between brick and frames and concrete & block.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
A 12-month guarantee comes as standard, so you are covered after we have gone.

What happens if it’s left?
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Mansfield, water from a failed joint in an older stone home can soak into timber and plaster.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

How the visit works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Outside jobs in Mansfield need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

Signs you need external mastic in Mansfield
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
The most common problems we see are:
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
For landlords with property near New Cumnock station, outside joints that have cracked can let damp into a rental, so check them between lets.

Mansfield buildings and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. 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.
Around Mansfield, as everywhere, external mastic is only as good as the preparation behind it.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Get split or bare joints resealed while the damage is small
- Avoid pressure-washing directly into sealant joints
- Show decorators and builders where the movement joints are
- Ask before painting over external sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
What affects the cost of external mastic
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- The number of rooms or windows
- Access and height
- When we can work, for business premises

- Where the job is, and your postcode
- Whether it has been sealed before
- Access, such as stairs, a lift or height
