Remedial sealant in Moffat, done properly
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. Common call-outs are for kitchen joints letting water behind the worktop and movement joints that have split or pulled away, on expansion joints, leaking tray & enclosure joints and mouldy bath & shower sealant.
In and around a place like Moffat, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are generally the first signs.

Different surfaces, different methods
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint is not the cause, we’ll say so.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
- Deal with small splits early
- Use a soft cloth, not a scourer, on silicone
Do not let anyone seal over it later. New silicone doesn’t bond to old.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. For a place like Moffat, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height

Why it’s worth doing now in Moffat
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. In a place like Moffat, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

What else we do in Moffat
Signs you need remedial sealant in Moffat
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. Then the only fix is removal and a new bead.
People usually contact us when they notice something like this:
- Floor or wall movement joints that have failed
- Leaks that keep coming back after resealing
- Mould trapped under a layer of silicone
- A second bead peeling off the first
Homes close to St John's Episcopal Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Moffat homes and their sealant
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. 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.
If you look after a building such as Moffat Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Can you fix a reseal that hasn’t worked?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long will it take to strip and reseal the joint?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. You’ll know the timing when we quote.
