FAQs for Netherthird
Will you come out to Netherthird?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work in hotels near Netherthird?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you guarantee remedial jobs?
Yes, with our one-year guarantee. If we’ve pointed out another problem, getting it fixed helps the new joint last.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
How we handle remedial sealant in Netherthird
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. Common call-outs are for sealant applied over old sealant that has lifted and torn expansion joints, on mouldy bath & shower sealant, failed movement joints and shrunken worktop sealant.
Bathrooms in smaller places like Netherthird work just as hard as those in the cities. Generally soft Scottish water means less limescale, but steam still lets mould into sealant and grout.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Tiles that have come away from the wall
- Older mastics that may need an asbestos check before removal
- Plumbing leaks behind walls or under trays
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Outside jobs in Netherthird need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Different surfaces, different methods
Windows & doors
Some leaks around windows come from the wall or the window itself. If the frame joint is not the cause, we will say so.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.

Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.

Signs you need remedial sealant in Netherthird
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. Then the only fix is removal and a new bead.
Any of these means the joints need attention:
- Floor or wall movement joints that have failed
- Over-sealed joints coming away
- Worktop sealant that has shrunk and split
- Smears and lumps from a botched reseal
Homes close to Church of St. John include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Find out why the sealant failed first
- Check ceilings under showers for marks
- Run the fan after every shower
- Always have old sealant cut out, not covered
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
