About our remedial sealant in Dumbiedykes
A joint that keeps failing normally has a reason. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will beat any new bead. Finding that cause comes before any new sealant. We’re often asked to deal with dark patches showing through the sealant and worktop sealant that has shrunk and split, across leaking tray & enclosure joints, expansion joints and shrunken worktop sealant.
Dumbiedykes is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Rooms like that are often small and slow to dry out, which is hard on sealant and grout.
Whatever the size of the job, you get the same 12-month guarantee.

Why act early in Dumbiedykes
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Wind-driven rain gets into any failed joint on the outside of a city building, and in Dumbiedykes, damp can spread through stone and plaster before anyone sees it.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Bathrooms and kitchens in Dumbiedykes
Dumbiedykes is close to 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. Edinburgh has a lot of tenement flats, in the Old and New Towns and well beyond, where a failed seal can soon reach the flat below.
If you look after a building such as Old Royal High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Edinburgh Waverley station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep movement joints clear of mortar and paint
- Check ceilings under showers for marks
- Keep bleach and abrasives off the bead
- Run the fan after every shower
Give the new sealant its full cure time: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.

The price is agreed before any work begins. It’s based on:
- Access and height
- Working hours on commercial sites

What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours, depending on how many layers have to come out. For a tenement in Dumbiedykes, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks

Common questions in Dumbiedykes
Do you take on hotel work around Dumbiedykes?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
I’m in a tenement in Dumbiedykes. Could worn sealant affect the flat downstairs?
It can. Tenement floors are usually timber, and water from a failed seal can find its way down to the flat below, and then the repair involves your neighbours too. Replacing tired sealant early is the simplest way to avoid that.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
What happens if the problem is the tray or the plumbing?
You will hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, so we won’t pretend it will.
Do you guarantee remedial jobs?
Yes, with our 12-month guarantee. Where we’ve flagged another fault, it needs fixing for the joint to last.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Can you take off two layers of silicone?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
