External & façade joints in Peel, Scottish Borders
External mastic in Peel from a team with over 20 years’ experience. 180+ five-star Google reviews and a 4.9 rating.
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
Keeping the joints in good condition
Aftercare is simple:
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
- Deal with leaking gutters that soak the joints below
- Make sure movement joints aren’t pointed over
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
External mastic for homes and businesses in Peel
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. We work on brickwork movement joints, concrete & block and joints between brick and frames, and people most often call us about hard, crazed mastic that has stopped moving and rigid filler in a joint that should flex.
External sealant needs dry surfaces, so outdoor work around Peel is planned around the weather. Tell us how to reach each wall, gutter and roofline.
All our work comes with a 12-month guarantee.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. 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.
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Cracked brickwork or render that needs a builder or plasterer
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
Where we work in Peel
- Concrete & block
- Façade panels
- Copings & trims
- Brickwork movement joints
- Joints between brick and frames
- Render & cladding joints
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.
When to call us in Peel
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.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
Peel House, about 0.1 miles south-west, is one of the historic houses in the wider area around Peel.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It usually takes anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we’re working on
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Surface by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.

Do you cover Peel for external mastic?

What information do you need?
Let us know what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Yes, we can. Several rooms, windows or areas can go on one quote.
What external mastic looks like in Peel
With historic houses such as Peel House (about 0.1 miles south-west) nearby, there’s older building stock in the area around Peel as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
If you let a flat or house near Galashiels station, split movement joints are easy to miss on a rental until damp shows inside.
