Remedial sealant in Gilmerton
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 one-year guarantee. If you have black mould underneath the bead and sealant applied over old sealant that has lifted, we can put it right.
Tenement flats are common in all four of Scotland’s big cities, alongside suburban houses and modern blocks. In a tenement, most bathrooms sit above someone else’s ceiling, so failed sealant around a bath or shower can soon become a neighbour’s problem.
Big or small, it’s backed by our one-year guarantee.

How the job changes by surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. Where it can be raked out, we replace it with flexible sealant.
Worktops & kitchens
A loose worktop splits its sealant. It needs fixing down first, and we’ll tell you if we find it.
Why it’s worth doing now in Gilmerton
Mould under a bead can’t be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. Wind-driven rain gets into any failed joint on the outside of a city building, and in Gilmerton, damp can spread through stone and plaster before anyone sees it.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

- More than 20 years in sealant work
- White, clear, grey or coloured to suit, where the product allows

Do you need remedial sealant in Gilmerton?
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Common reasons people contact us are:
- Kitchen joints letting water behind the worktop
- Thick, messy sealant smeared over tiles
- Sealant applied over old sealant that has lifted
- Repeat leaks from the same joint
Managing a site like Gracemount High School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
Questions to ask before booking
- Is the old sealant removed completely?
- What insurance they hold
- How the surfaces are prepared before sealing
- When the joint can take water or movement
Remedial sealant in Gilmerton: local notes
In Scotland, private landlords have to meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that does not dry out.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look for stains below bathrooms now and then
- Deal with small splits early
- Do not add new sealant on top of old
- Air the bathroom so the sealant can dry
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Landlords, agents and businesses in Gilmerton
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. In a city area like Gilmerton, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
