Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
About our external mastic in Winchburgh
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. We are often asked to deal with brick movement joints where the sealant has split and water getting into walls through failed joints, on brickwork movement joints, render & cladding joints and copings & trims.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Around Winchburgh, water from a failed joint in an older stone home can soak into timber and plaster.
What you pay reflects the work, not guesswork. That is why we ask about the job first.

Walls and rooflines in Winchburgh
Winchburgh is within about 3 miles of 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. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
For landlords with property near Uphall station, split movement joints are easy to miss on a rental until damp shows inside.

What happens on the day
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. Outdoor work around Winchburgh depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at every joint and agree a colour to suit the wall.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can

Winchburgh: your questions answered
Will you come out to Winchburgh?
Yes, Winchburgh is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is external mastic in a coastal place like Winchburgh any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render. Exterior sealants come in a good range of colours.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you have insurance?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Common problems we fix in Winchburgh
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
It’s worth asking for a quote if you see:
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Joints pointed up with cement by mistake
- Failed sealant between panels on a façade
For site and facilities teams at buildings such as Winchburgh Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Honest limits
A few problems are outside what sealant work can do:
- Structural movement, which needs a surveyor or engineer
- Damp that is not coming from the joint
- Adding movement joints to masonry that has none
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.
