Questions from Pentonville
Can parking be tricky for a visit in Pentonville?
Parking in Pentonville, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near Essex Road station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
What does regrouting cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Should corners be grouted or sealed?
Corners get silicone, not grout. They flex and grout can’t take that movement.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Can you change the grout colour?
Yes. It’s the ideal time to change it. Mention the colour you have in mind when you phone 0345 464 0079 or send us an email.
About our regrouting in Pentonville
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 can get in behind the tiles. We rake it out and replace it and renew the silicone at the edges. We are often asked to deal with discoloured grout on otherwise sound tiles and a grout colour that no longer suits the room, across kitchen splashbacks, tiled floors and shower walls.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Pentonville more than a cosmetic job.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Regrouting in Pentonville: local notes
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Essex Road station change hands often, and stained grout drags a rental down, and regrouting between lets puts that right. If you look after a building such as St John Evangelist RC Primary 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.

Common problems we fix in Pentonville
Some grout fails because it was mixed or laid badly. If it was mixed too wet or not pressed in firmly tends to wash out early.
It’s worth asking for a quote if you see:
- Grout washed out of a shower
- Grout stained black or orange that won’t clean
- Corners filled with grout instead of silicone
- Crumbling grout between the tiles
Pentonville is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

- What happens if the job turns out different
- Which colour the sealant will be
How to look after the new joints
After the cure time, these simple habits help:
- Do not use strong acidic cleaners on grout
- Wipe water off the walls when you’re done
- Rinse soap off the tiles after each shower
- Clean with a soft brush, not anything metal
Have any tile that moves checked right away. Movement will crack the new grout and open a path for water.
Leaving failed grout can mean tiles come loose. Once that happens, regrouting won’t fix it, so it’s worth acting early.
Why it’s worth doing now in Pentonville
Cleaning products may brighten grout for a time, but mould that has got into grout normally comes back. Replacing the grout and resealing the edges is a lasting fix. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Pentonville, the repair is bigger than the sealant job would have been.
Combining jobs into one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours, or longer for a fully tiled room. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Pentonville. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by checking the tiles for any that are loose or hollow.
- The old grout comes out to a consistent depth, without damaging the tiles.
- We vacuum the joints and clean out the dust.
- We fill the joints with new grout, then clean the tiles.
- We reseal the internal corners and edges with silicone.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
