Smithfield: your questions answered
Do you work in hotels near Smithfield?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can you help a landlord with a rental near Farringdon station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you guarantee regrouting?
Our one-year guarantee covers every job.
About our regrouting in Smithfield
Across Smithfield, we regrout tiled showers, bathrooms and kitchens. The old grout is raked out, the joints cleaned and new grout laid, finished with new silicone at the edges. Typical jobs include grout that’s cracking and breaking up and grout that stays dark however much it’s cleaned, across kitchen splashbacks, bathroom wall tiles and tiled floors.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Smithfield more than a cosmetic job.
Each job carries a 12-month guarantee.

Surface by surface
Bathroom floors
Grout on a floor is walked on as well as wetted. It wears and darkens over time.
Bathroom wall tiles
Tiles away from the shower stay drier but still stain and crack. New grout freshens them up.
Common problems we fix in Smithfield
Grout that was put in corners cracks because those joints flex. Those joints should be silicone, and if they’re grouted, a crack soon lets water in.
Keep an eye out for any of the following:
- Corners filled with grout instead of silicone
- Old grout in a dated colour
- Splashback grout that has darkened
- Discoloured grout on otherwise sound tiles
Homes close to St Bartholomew-the-Less include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
Before you book anyone
- What happens if they find a problem under the old sealant
- Whether you can choose the colour
- What the quote includes, VAT included or not
- Whether the sealant suits the joint
The process
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours, or longer for a fully tiled room for a typical job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- 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.
- New grout is pressed into the joints and the tiles are cleaned.
- Silicone goes into the corners and along the edges.
Preparing for the visit
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Advice
Regrouting around Smithfield
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.
As a London address, Smithfield can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Farringdon station, stained grout drags a rental down, and regrouting between lets puts that right.
Smithfield is about 1 mile north of London, in Greater London. Whether you are in the middle of Smithfield or further out, regrouting is available for homes and businesses alike. Smithfield is one of 764 towns and villages in Greater London where we work.
Every address in EC1V, EC1P and EC1R is covered for regrouting, from the main roads to the quietest streets. If you need regrouting at a property on Oat Lane, Shoe Lane and Long Lane or anywhere close by, our applicators can take on the job. You will find Smithfield on the A1 and A4, so it’s easy for us to get to with everything needed for regrouting.

What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Water coming from plumbing rather than grout
- Failed tanking or waterproofing under the tiles
- Damaged tiles that need replacing
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Why deal with it now?
Grouting over old grout rarely lasts. It sits thinly on top and soon flakes away. Raking out to a consistent depth gives the new grout something to hold. In a flat in Smithfield, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Aftercare tips
After the cure time, these simple habits help:
- Clean grout with a mild bathroom cleaner
- Clean with a soft brush, not anything metal
- Keep an eye on the silicone along the edges
- Use a squeegee on the tiles after showering
Before we leave, you will know when the shower can be used. Please follow it, and go gently on the grout at first.
Once grout cracks, it tends to get worse. Water gets in behind and the tiles can start to loosen and early regrouting can avoid a much bigger job.
