Duns Remedial Sealant
Remedial sealant in Duns from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Sealant peeling off a dusty or damp surface
- Wide, uneven beads that look worse than the old ones
- Worktop sealant that has shrunk and split
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Use a soft cloth, not a scourer, on silicone
- Report a tray that rocks or a worktop that lifts
- Keep movement joints clear of mortar and paint
- Ask why a joint failed before redoing it
Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just send an email to info@mrmastic.co.uk.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Remedial sealant in Duns
In Duns, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on shrunken worktop sealant, botched or over-sealed joints and failed movement joints, and the jobs we see most are torn expansion joints and mould trapped under a layer of silicone.
For a place like Duns, the job is the same as anywhere: old material out, joints cleaned and dried, and a fresh, even finish. We just plan the journey and access beforehand.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
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.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
- A cracked shower tray or bath (that needs repair or replacing)
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
What we seal
- Failed movement joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
When to call us in Duns
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
Common reasons people contact us include:
- Products that weren’t meant for the joint
- Movement joints that have split or pulled away
- Leaks that keep coming back after resealing
- Dark patches showing through the sealant
If you live in an older home near Old Parish Church, walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before you book
- Are they insured?
- When the joint can take water or movement
- What the quote includes, VAT included or not
- Is the old sealant removed completely?

How the job changes by surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
How it works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job generally takes a few hours for most joints, depending on how much old sealant has to come out. Outside jobs in Duns need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
