Remedial sealant in Longstone
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we will tell you rather than reseal something that will not fix it. Common call-outs are for a shower that leaks however often it’s resealed and thick, messy sealant smeared over tiles, across failed movement joints, leaking tray & enclosure joints and botched or over-sealed joints.
Longstone is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Space is tight and ventilation can be poor, and steam with nowhere to go is what turns sealant black and grout grey.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What affects the cost of remedial sealant
We do not publish a price list. The quote depends on:
- The type of sealant required
- When we can work, for business premises
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
Do you need remedial sealant in Longstone?
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
It’s worth asking for a quote if you see:
- Sealant applied over old sealant that has lifted
- Thick, messy sealant smeared over tiles
- A shower that leaks however often it’s resealed
- Worktop sealant that has shrunk and split
Managing a site like Merchiston Castle School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- Which colour the sealant will be
- Whether VAT is included
- Whether all the old sealant comes out first
- What the cure time is

How it works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Longstone, 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.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
Getting a quote

Remedial sealant around Longstone
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out. 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.
If you let a flat or house near Kingsknowe station, a joint that keeps failing is best fixed properly while the property is empty.
Longstone is about 3 miles south-west of Edinburgh, in Edinburgh. Longstone gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Across Edinburgh, we cover 175 places, and Longstone is one of them.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. In a tenement flat in Longstone, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
Why us?

FAQs for Longstone
Can a failed shower seal in a tenement flat in Longstone leak into the flat below?
Yes, it can. In a tenement, water that gets past failed sealant or cracked grout can run under the bath or tray and through to the ceiling below, and then the repair involves your neighbours too. Replacing tired sealant early is the simplest way to avoid that.
Is Longstone in your area for remedial sealant?
Yes. Our work covers the whole of Scotland, and Longstone is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Can landlords and businesses book you?
Yes, regularly. Several properties can go on one quote.
Different surfaces, different methods
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces.
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.
