Remedial sealant in Mail
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. If you have sealant applied over old sealant that has lifted and a shower that leaks however often it’s resealed, we can help.
In and around a place like Mail, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.
You’re covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What we’re called out for in Mail
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Look out for any of the following:
- Floor or wall movement joints that have failed
- Thick, messy sealant smeared over tiles
- Decorators’ caulk around a bath or shower
- Kitchen joints letting water behind the worktop
Around Mail, as everywhere, remedial sealant is only as good as the preparation behind it.
Before you book anyone
- What preparation is included
- Who does the work, and how experienced they are
- When the joint can take water or movement
- Is VAT in the price?
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours, depending on how many layers have to come out. Outside jobs in Mail need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
Getting ready for the visit
- Mention any parking rules near the property
- Clear the area around the work
- Mention any tricky access

Why it’s worth doing now in Mail
Another bead over the top will not fix a failed joint. It can’t bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In an older home around Mail, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why Mail customers choose us
- 20+ years of sealant experience
- We leave the area clean and tidy
- Old sealant always removed completely
- A choice of colours where the product allows

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Sealant in an older building that needs testing for asbestos first
- A tray or worktop that needs refixing first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
Where we work in Mail
- Shrunken worktop sealant
- Expansion joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Failed movement joints
- Mouldy bath & shower sealant
How to look after the new joints
A little care helps the new joints last. We recommend:
- Act on a lifting corner straight away
- Find out why the sealant failed first
- Have loose fittings fixed before resealing
- Clean sealant with mild products only
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
Questions from Mail
Is remedial sealant in Mail guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like Mail?
Yes. Mail is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Can you remove old sealant without damaging the bath?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.

Remedial sealant around Mail
Mail is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. 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.
Homes close to Mail Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
