Remedial sealant in Laggan, done properly
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. If you have dark patches showing through the sealant and worktop sealant that has shrunk and split, we can put it right, on leaking tray & enclosure joints, expansion joints and failed movement joints alike.
In and around a place like Laggan, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are generally the first signs.
There’s a 12-month guarantee on every job.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Do not point over movement joints
- Always have old sealant cut out, not covered
- Check ceilings under showers for marks
- Act on a lifting corner right away
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
Why deal with it now?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it, and the joint treated and dried before resealing. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Questions from Laggan

Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Laggan within the area you cover?
Yes, Laggan is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks generally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.

The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before we start. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Around Laggan, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- 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.
Preparing for the visit
- Tell us if parking is tricky
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can

What remedial sealant looks like in Laggan
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black. In Scotland, private landlords have to 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.
Around Laggan, as everywhere, remedial sealant is only as good as the preparation behind it. Homes close to South Laggan Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Laggan is about 37 miles south-west of Inverness, in Highland. Laggan gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee.

Surface by surface
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
