How we handle remedial sealant in New Town
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you email us at info@mrmastic.co.uk. We work on shrunken worktop sealant, expansion joints and mouldy bath & shower sealant, and people most often call us about dark patches showing through the sealant and gaps opening along the back of the worktop.
From stone-built tenements to new flats and suburban houses, New Town is in a city with every kind of home. Scottish water is generally soft, so limescale is less of a problem than in hard-water areas, but mould still grows into sealant and grout in a steamy bathroom.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Leave it or put it right?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. For landlords in New Town, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

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. It normally takes a few hours, depending on how many layers have to come out. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In New Town, 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.
- 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.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Move anything stored near the joints
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
How to get a quote

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the quote in New Town
Call for a quick quote. What matters most is:
- Mould in or behind the old joints
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- The size of the job
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Helping us quote
When you contact us, these details help:
- Whether it’s a home or a business
- The rough size of the job
- A few photos by email, if you can
- If someone has resealed it before
If you are in New Town and need remedial sealant, email us at info@mrmastic.co.uk. Tell us what the problem is and where, and we will agree the price before any work begins.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Don’t add new sealant on top of old
- Have loose fittings fixed before resealing
- Use a soft cloth, not a scourer, on silicone
- Run the fan after every shower
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
New Town homes and their sealant
New Town 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. Tenement flats are common across Edinburgh, where a failed seal can soon reach the flat below.
Letting a property close to Edinburgh Waverley station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as London Street Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. If you live in an older home near St Andrew's and St George's West Church, older homes can move a little, which is hard on rigid grout and tired sealant.
New Town is about 1 mile north of Edinburgh, in Edinburgh. Whether you are in the middle of New Town or further out, we cover remedial sealant for every kind of property, from flats and houses to offices and hotels. We cover 175 towns and villages across Edinburgh, large and small.
All of EH3, EH1 and EH2 is within our area for remedial sealant. If you need remedial sealant at a property on York Lane, Meuse Lane and Canon Lane or a nearby road, we can help. If you’re just outside New Town, we cover Bellevue (1 mile north-east), Broughton (1 mile east), Canonmills (1 mile north), Greenside (1 mile east) and Gayfield (1 mile east). We also work in nearby towns such as Queensferry (8 miles west), South Portobello (3 miles east), Southhouse (4 miles south-east), Gilmerton (4 miles south-east), Slateford (3 miles south-west) and Gracemount (4 miles south-east).
What’s near New Town

How the job changes by surface
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried ahead of a new anti-fungal bead.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Your questions about remedial sealant in New Town
Do you take on hotel work around New Town?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
I’m in a tenement in New Town. Could worn sealant affect the flat downstairs?
Yes. With flats above and below, a leak from a failed seal rarely stays in one flat. A proper reseal, with all the old sealant cut out, stops it at the source.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
How long does the work take?
It takes a few hours for most joints, depending on how much old sealant has to come out. We will give you a timescale when we quote.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
