How we handle remedial sealant in Swanston
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we will tell you rather than reseal something that will not fix it. We work on failed movement joints, expansion joints and mouldy bath & shower sealant, and the jobs we see most are smears and lumps from a botched reseal and caulk or the wrong sealant used in a wet area.
Being further from a city does not change the work: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. The journey and access are simply planned in advance.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Honest limits
In fairness, there are a few things sealant will not fix:
- A bath, tray or worktop that moves until it’s properly fixed
- A cracked shower tray or bath (that needs repair or replacing)
- Failed tanking or loose tiles behind the sealant
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal

What the job involves on each surface
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. We strip it back so we can see the joint, then reseal neatly.
What we do, step by step
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for most joints, depending on how much old sealant has to come out from start to finish. Outside jobs in Swanston need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can

Your questions about remedial sealant in Swanston
Do you work for landlords with property near Slateford station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Is Swanston within the area you cover?
Yes. Swanston is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Can you fix a reseal that hasn’t worked?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
How long does the work take?
Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours, and we confirm the time with your quote.
Leave it or put it right?
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Get the cause of a repeat leak found before resealing
- Report a tray that rocks or a worktop that lifts
- Act on a lifting corner right away
- Always have old sealant cut out, not covered
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies. 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 does not dry out.
For an older house near a landmark such as Fairmilehead Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to Slateford station? Then a joint that keeps failing is best fixed properly while the property is empty.
