Regrouting in Thornhill
Grout is the filler between your tiles, and sealant is what goes along the bath, tray or worktop. When grout cracks or washes out, water has a way in behind the tiling. We rake it out and replace it and renew the silicone at the edges. If you are dealing with crumbling grout between the tiles and floor grout that won’t come clean, we can help, whatever the surface.
A bathroom in a place like Thornhill gets the same daily wear as one in a city flat. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
All of our work is guaranteed for twelve months, in Thornhill and everywhere else we cover.

What affects the quote in Thornhill
The quote reflects the job in front of us. We take into account:
- The number of rooms or windows
- The number and length of the joints
- Any mould that needs treating
- Which sealant suits the joint
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
What to tell us when you ask for a quote:

Why it’s worth doing now in Thornhill
Grouting over old grout rarely lasts. A thin skin on top tends to break off. Removing the old grout to an even depth lets the new grout key in properly. Around Thornhill, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What you get with us
- Any old sealant cut out fully, not covered over
- 20+ years of sealant experience
- A 12-month guarantee on all work
- Full insurance on every job

What regrouting looks like in Thornhill
There are hotels and other places to stay in and around Thornhill. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that doesn’t dry out.
Around Thornhill, as everywhere, regrouting is only as good as the preparation behind it. If you look after a building such as Wallace Hall Academy, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
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.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Use a soft brush rather than a wire one
- Look at the sealant in the corners now and then
- Don’t ignore a tile that feels loose
- Keep harsh bleach and acid cleaners off the grout
Before we leave, you’ll know when the shower can be used. Stick to that time, and avoid scrubbing the new grout hard for the first few days.
Small problems with grout are quick to put right. Left for a few years, they can become a leak, so get it looked at when you notice it.
