What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Cummingston 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.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on

About our external mastic in Cummingston
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 work on brickwork movement joints, façade panels and concrete & block, and people most often call us about sealant that has lost its bond to the brick or render and weathered mastic that no longer stretches.
External sealant needs dry surfaces, so outdoor work around Cummingston is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
Each job carries a 12-month guarantee.

Outside joints around Cummingston
Cummingston is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For jobs in and around Cummingston, choosing the right material for each joint is as important as a tidy finish. Around Cummingston, as everywhere, external mastic is only as good as the preparation behind it.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Leave the joints unpainted unless we’ve said otherwise
- Fix overflowing gutters above sealed joints
- Never let anyone fill a movement joint with mortar
- Walk round the building once a year and look at the joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Honest limits
A few problems are outside what sealant work can do:
- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
- Render that is blown, hollow or coming away
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.

What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Common questions in Cummingston
Is external mastic in a coastal place like Cummingston any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover Cummingston for external mastic?
Yes, Cummingston is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it does not stand out.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you have insurance?
Yes. We are fully insured.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
