How the job changes by surface
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before any new sealant goes on.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned before backing and resealing.
Remedial sealant in Powderhall, done properly
Two decades of sealant work means we recognise most failures quickly. We are ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. Typical jobs include floor or wall movement joints that have failed and kitchen joints letting water behind the worktop, on failed movement joints, expansion joints and leaking tray & enclosure joints.
From stone-built tenements to new flats and suburban houses, Powderhall is in a city with every kind of home. Generally soft Scottish water means less limescale, but steam and poor ventilation still let mould into the sealant and grout.

Do you need remedial sealant in Powderhall?
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Look out for any of the following:
- Dark patches showing through the sealant
- Caulk or the wrong sealant used in a wet area
- A shower that leaks however often it’s resealed
- Over-sealed joints coming away
For landlords with property near Edinburgh Waverley station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
What your quote should include
- When the joint can take water or movement
- What insurance they hold
- The length of the guarantee
- Whether they seal over old material or remove it
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Why deal with it now?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

What remedial sealant looks like in Powderhall
Powderhall is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that does not dry out.
For an older house near a landmark such as St Philip's Church And Hall, walls and floors in older homes can move, and sealant and grout show it first. Schools such as Drummond Community High School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
