Remedial sealant for North Dell and the surrounding area: careful preparation, the right product and tidy work. Ask us for a quick quote.
- Smears and lumps from a botched reseal
- Beads that never stuck properly
- Over-sealed joints coming away
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours, depending on how many layers have to come out. Outside jobs in North Dell need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We look at how the sealant has failed and check for movement or a leak path.
- 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.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

Related advice
Remedial sealant in North Dell, done properly
Remedial jobs in North Dell usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. We work on leaking tray & enclosure joints, botched or over-sealed joints and failed movement joints, and people most often call us about decorators’ caulk around a bath or shower and sealant applied over old sealant that has lifted.
In and around a place like North Dell, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
Our work is backed for twelve months, in North Dell and everywhere else we cover.

Questions from North Dell
Is North Dell in your area for remedial sealant?
Yes. Our work covers the whole of Scotland, and North Dell is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Is North Dell within the area you cover?
Yes. North Dell is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you guarantee remedial jobs?
Yes, for 12 months. Where we have flagged another fault, it needs fixing for the joint to last.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, so we find that first.
How long does the work take?
The number of joints and layers decides it. You will have a timescale before any work begins.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. It will not solve:
- Plumbing leaks behind walls or under trays
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Tiles that have come away from the wall

What else we do in North Dell
DIY versus a professional finish
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. Everything old must be removed first.
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 fails, we can still redo it.
Bathrooms and kitchens in North Dell
North Dell 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. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
For an older house near a landmark such as Church of Scotland, walls and floors in older homes can move, and sealant and grout show it first. In and around North Dell, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

What the job involves on each surface
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned before backing and resealing.
How to look after the new joints
Aftercare is simple:
- Never fill a movement joint with mortar or grout
- Keep the room well ventilated
- Check trays and worktops do not move
- Check ceilings under showers for marks
Clean gently: no scraping, scouring pads or harsh chemicals.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
