External & façade joints in Gorebridge, Midlothian
We cover Gorebridge for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
External mastic in Gorebridge, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. We work on render & cladding joints, concrete & block and façade panels, and people most often call us about plants rooting in failed movement joints and sealant that has lost its bond to the brick or render.
Outside joints can only be sealed when they’re dry, so work in Gorebridge depends on the weather. Tell us how to reach each wall, gutter and roofline.
There’s a 12-month guarantee on every job.

When to call us in Gorebridge
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Keep an eye out for any of the following:
- Weathered mastic that no longer stretches
- Leaking joints around cladding and façade panels
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
If you look after a building such as Newbattle Community High School, larger buildings have long runs of movement joint that eventually need resealing.

What sealant work cannot fix
A few problems are outside what sealant work can do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

FAQs for Gorebridge
Can you help a landlord with a rental near Gorebridge station?
Yes, we work for letting agents and landlords. Just email us at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Do you cover smaller places like Gorebridge?
Yes, Gorebridge is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How the visit works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building for a typical job. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us about any water getting in
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

Related advice
Looking after it afterwards
Looking after new joints is easy:
- Tell anyone working on the walls about the movement joints
- Clear growth from the base of walls and joints
- Wash walls gently around the sealant
- Walk round the building once a year and look at the joints
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.

What the job involves on each surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
Outside joints around Gorebridge
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. With historic houses such as Melville Castle (about 3.8 miles north-west) nearby, there’s older building stock in the area around Gorebridge as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Gorebridge station, split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Gorebridge Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why act early in Gorebridge
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Gorebridge, water from a failed joint in an older stone home can soak into timber and plaster.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
