How we handle external mastic in Glencraig
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. We work on joints between brick and frames, brickwork movement joints and façade panels, and common reasons people get in touch are hard, crazed mastic that has stopped moving and sealant pulling away from one side of the joint.
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.
All our work comes with a 12-month guarantee, wherever you are in Fife.

Surface by surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.

Outside joints around Glencraig
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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.

How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. Outdoor work around Glencraig depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Clear the area around the work
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed

How to look after the new joints
After the cure time, these simple habits help:
- Fix overflowing gutters above sealed joints
- Show decorators and builders where the movement joints are
- Never let anyone fill a movement joint with mortar
- Get split or bare joints resealed while the damage is small
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
What we’re called out for in Glencraig
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint.
Most people get in touch when they notice something like this:
- Failed sealant between panels on a façade
- Movement joints with cracked, split or missing sealant
- Weathered mastic that no longer stretches
- Moss and dirt in joints with no sealant left
Schools such as Lochgelly High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

FAQs for Glencraig
Is Glencraig within the area you cover?
Yes, Glencraig is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Glencraig in your area for external mastic?
Yes. We work across all of Scotland, and Glencraig is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

Why act early in Glencraig
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
