Knightswood Regrouting
Raking out old, cracked or stained grout and regrouting tiled walls and floors for householders, landlords and businesses in Knightswood. Fully insured, ARBOMaster approved and guaranteed for a year.
- Shower grout that has worn away
- Corners filled with grout instead of silicone
- Grout that makes sound tiles look old
DIY versus a professional finish
If you do try it yourself, take your time over the 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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Regrouting for homes and businesses in Knightswood
Grout fills the gaps between tiles, while sealant goes where tiles meet a bath, tray or worktop. When grout cracks or washes out, water can get in behind the tiles. We rake it out and replace it, then reseal the corners and edges. If you have dirty, worn grout on a tiled floor and grout stained black or orange that won’t clean, we can help, whatever the surface.
Knightswood is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Space is tight and ventilation can be poor, and steam with nowhere to go is what turns sealant black and grout grey.
There’s a 12-month guarantee on every job, whatever its size.

Questions from Knightswood
Can you do regrouting in Knightswood?
Yes, Knightswood is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Could a leaking bath seal in my Knightswood flat reach the neighbours below?
Yes, it can. In a tenement, water that gets past failed sealant or cracked grout can run under the bath or tray and through to the ceiling below. Replacing tired sealant early is the simplest way to avoid that.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long does regrouting take?
Typically it takes a few hours for a shower enclosure, longer for a whole room. Larger jobs naturally take longer, and we’ll say how long yours will take.
When can I use the shower again?
We’ll tell you on the day. It depends on the grout and the sealant used so please stick to it.
When to call us in Knightswood
A poor original job is a common cause. If it was mixed too wet or not pressed in firmly tends to wash out early.
The problems people usually mention when they call are:
- Splashback grout that has darkened
- Grout in corners that has cracked
- Shower grout that has worn away
- Grout that makes sound tiles look old
Homes close to Knightswood St Margaret's Parish Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Quotes for regrouting in Knightswood
The price is agreed before any work begins. It’s based on:
- How easy the joints are to reach
- Any working-time requirements on site
- Mould in or behind the old joints
- The size of the job
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Bathrooms and kitchens in Knightswood
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 does not dry out. Sandstone tenements are a big part of Glasgow’s housing, where most bathrooms sit above another flat.
If you let a flat or house near Westerton station, a regrout while the flat is empty is quicker than working around a tenant. If you look after a building such as Knightswood Secondary School, 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.

The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours, or longer for a fully tiled room. Inside a flat in Knightswood, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- Every tile area is checked for hollow or loose tiles first.
- The old grout is removed to an even depth.
- The joints are vacuumed clean.
- We regrout the joints and clean the tile faces.
- We finish with silicone in the moving joints.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

Advice
How the job changes by surface
Shower walls
The grout in a shower takes the brunt of the water. We replace it, and reseal the corners.
Kitchen splashbacks
Kitchen grout collects grease and food splashes. Once it’s stained, new grout is often the only fix.
Landlords, agents and businesses in Knightswood
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
