Thurso Regrouting
Problem with your tiled areas in Thurso? We remove the old material, prepare the joints and seal them properly.
- Floor grout that has worn and darkened
- Gaps where the shower grout has gone
- Crumbling grout between the tiles
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on the area and we leave things clean and tidy. Parking around Thurso is rarely difficult, though older streets in the centre can be tight. If you are in a flat with a shared stair or a door entry system, let us know when you book.
- First, we check for loose or hollow tiles and point out any we find.
- Old grout is raked out to a consistent depth without chipping the tiles.
- Dust and debris are vacuumed out of every joint.
- Fresh grout goes into the joints and the tile faces are wiped clean.
- Corners and edges are resealed with flexible silicone, not grout.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

Regrouting in Thurso, done properly
Grout is the filler between your tiles, while sealant goes where tiles meet a bath, tray or worktop. Once grout starts to crack or wash away, water can get in behind the tiles. Our job is to rake it out and put new grout in, then reseal the corners and edges. If you’re dealing with crumbling grout between the tiles and grout stained black or orange that won’t clean, we can put it right, on shower walls, wet rooms and tiled floors alike.
Around Thurso, we see everything from older flats to family homes on newer estates. The jobs are much the same in all of them: mouldy beads, gaps where a bath has moved and grout that is cracked or stained.
Big or small, you get the same 12-month guarantee in Thurso and across Highland.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Why it’s worth doing now in Thurso
It’s tempting to fill a few cracks yourself, but patched grout rarely matches the rest, and the old grout keeps failing around them. Regrouting the whole area gives an even, lasting finish. Scottish weather finds any gap, and in a town like Thurso, failed outside joints soon let damp into walls. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Signs you need regrouting in Thurso
Hard water and soap leave a film on grout and stick to it. In time the grout under it darkens and breaks down, which is when replacing it makes sense.
Most people get in touch after spotting something like this:
- Grout washed out of a shower
- Corners filled with grout instead of silicone
- Discoloured grout on otherwise sound tiles
- Stained grout that cleaning won’t shift
If you let a flat or house near Thurso station, clean grout and fresh sealant between tenancies make a bathroom look cared for again.

Common questions in Thurso
Do you cover Thurso for regrouting?
Yes, Thurso is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Is regrouting in Thurso guaranteed?
All our work, in Thurso and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Should corners be grouted or sealed?
Internal corners and edges are sealed with flexible silicone. Grout in those joints cracks as the building moves.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Regrouting around Thurso
Thurso is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, 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. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
Schools such as Thurso High School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Run the extractor fan during and after a shower
- Check the corner silicone every few months
- Get any tile that moves checked promptly
- Skip wire brushes and scourers
A squeegee or cloth over the tiles after use keeps water off the grout. Run the extractor fan or open a window so the grout dries between uses.
Grout that is washing out of a shower shouldn’t be left. Every shower pushes more water into the gaps and it can end up in the wall or the ceiling below.
What we can’t put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- A leaking shower valve or waste
- Failed tanking or waterproofing under the tiles
- Tiles that are loose or hollow behind
