How we handle remedial sealant in Duddingston
Two decades of sealant work means we recognise most failures quickly. We’re fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. We’re often asked to deal with black mould underneath the bead and sealant applied over old sealant that has lifted, across failed movement joints, mouldy bath & shower sealant and botched or over-sealed joints.
A bathroom in a place like Duddingston gets the same daily wear as one in a city flat. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
All our work comes with a one-year guarantee, wherever you are in Edinburgh.

Surface by surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Duddingston: your questions answered
Do you work for hotels and guest houses in Duddingston?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Will you come out to Duddingston?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Someone sealed over the old bead. Can you fix it?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Run the fan after every shower
- Always have old sealant cut out, not covered
- Check ceilings under showers for marks
- Keep movement joints clear of mortar and paint
Clean gently: no scraping, scouring pads or harsh chemicals.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.
Bathrooms and kitchens in Duddingston
Duddingston is within about 2 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
Managing a site like Holy Rood High School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. In the older streets around Duddingston Kirk, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

When to call us in Duddingston
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould. At that point it has to come out.
The problems people generally mention when they call are:
- Wide, uneven beads that look worse than the old ones
- Sealant peeling off a dusty or damp surface
- Torn expansion joints
- A shower that leaks however often it’s resealed
If you let a flat or house near Brunstane station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Duddingston may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
