Remedial sealant & repairs in Greenhill, Edinburgh
Failed sealant joints in Greenhill need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Torn expansion joints
- Black mould underneath the bead
- Gaps opening along the back of the worktop
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
About our remedial sealant in Greenhill
Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out. Common call-outs are for thick, messy sealant smeared over tiles and black mould underneath the bead, on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant.
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, and that is as true in Greenhill as anywhere in the city.
All of our work is guaranteed for twelve months.

Quotes for remedial sealant in Greenhill
There’s no set price list, because jobs vary so much. The quote depends on:
- The old material and how stubborn it is
- Any working-time requirements on site
- Whether the work is at height
- The number and length of the joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- The rough size of the job
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Landlords, agents and businesses in Greenhill
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Keep movement joints clear of mortar and paint
- Always have old sealant cut out, not covered
- Act on a lifting corner straight away
- Clean sealant with mild products only
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start.
Don’t keep resealing the same joint. Have someone find out why, or the next bead will go the same way.
Signs you need remedial sealant in Greenhill
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
Any of these means the joints need attention:
- Black mould underneath the bead
- Sealant peeling off a dusty or damp surface
- Gaps opening along the back of the worktop
- Smears and lumps from a botched reseal
If you live in an older home near Morningside United Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What else we do in Greenhill
What remedial sealant looks like in Greenhill
Greenhill is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Edinburgh has a lot of tenement flats, in the Old and New Towns and well beyond, and in a tenement, a leaking seal can reach the neighbours below.
Rented homes near Haymarket station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Schools such as Iain Tomlin School of Music are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What the job involves on each surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Greenhill questions
I’m in a tenement in Greenhill. Could worn sealant affect the flat downstairs?
Yes. With flats above and below, a leak from a failed seal rarely stays in one flat. Cutting out the old sealant and laying a fresh bead puts a stop to it.
Do you take on hotel work around Greenhill?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Someone sealed over the old bead. Can you fix it?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Can you strip sealant from an acrylic tray safely?
Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. Any existing damage is pointed out before we start.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What we do, step by step
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for most joints, depending on how much old sealant has to come out. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Greenhill, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
