Remedial Sealant in Biggar
We cover Biggar for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Products that weren’t meant for the joint
- A shower that leaks however often it’s resealed
- Sealant that came away because the surface wasn’t prepared
Should I try it myself first?
If you’re set on DIY, put the effort into 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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
About our remedial sealant in Biggar
In Biggar, as anywhere, remedial jobs tend to look alike: 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. Typical jobs include a shower that leaks however often it’s resealed and worktop sealant that has shrunk and split, on shrunken worktop sealant, failed movement joints and expansion joints.
For a place like Biggar, the job is the same as anywhere: old material out, joints cleaned and dried, and a fresh, even finish. The journey and access are simply planned in advance.
You get a one-year guarantee, the same in Biggar as everywhere else we work.

Questions from Biggar
Can you do remedial sealant in Biggar?
Yes. Our work covers the whole of Scotland, and Biggar is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Is Biggar within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Which products do you use?

Yes. Our 12-month guarantee covers the work, and we’re ARBOMaster approved.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
What happens if the problem is the tray or the plumbing?
We’ll tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we will not pretend it will.
Where do you work from?

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours, depending on how many layers have to come out. Somewhere like Biggar may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks

Remedial sealant in Biggar: local notes
Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of 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.
If you live in an older home near Biggar Church, walls and floors in older homes can move, and sealant and grout show it first.

How the job changes by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and tell you about any damage we find.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Run the fan after every shower
- Keep movement joints clear of mortar and paint
- Use a soft cloth, not a scourer, on silicone
- Never seal over old silicone
Keep the room ventilated: run the fan during and after showers, or open a window.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
Do you need remedial sealant in Biggar?
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould. Then the only fix is removal and a new bead.
These are the problems we are asked about most:
- Kitchen joints letting water behind the worktop
- Leaks that keep coming back after resealing
- Beads that never stuck properly
- A second bead peeling off the first
If you look after a building such as Biggar High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- What happens if the job turns out different
- Which sealant they’ll use, and why
- Are they insured?
- Whether all the old sealant comes out first
