About our regrouting in Botany Bay
Grout fills the gaps between tiles, and sealant is what goes along the bath, tray or worktop. Once grout starts to crack or wash away, water has a way in behind the tiling. Our job is to rake it out and put new grout in and renew the silicone at the edges. If you have kitchen splashback grout stained by grease and cracked or crumbling grout lines, we can put it right, whatever the surface.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Botany Bay, that is a good reason to put tired sealant and grout right early.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Leave it or put it right?
It’s tempting to fill a few cracks yourself, but the patches often do not match and the old grout carries on failing. Doing the full area gives you one colour and sound joints throughout. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Questions from Botany Bay
Can worn sealant in a flat in Botany Bay cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Can you help a landlord with a rental near Crews Hill station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you regrout part of a bathroom, like the shower?
Yes. We will look at the rest of the room too and let you know if more needs doing.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Do you guarantee regrouting?
Our one-year guarantee applies to all our work, and we’re fully insured.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Other services in Botany Bay
Surface by surface
Wet rooms
In a wet room, the whole floor gets wet, so sound grout really matters. We check the tiles first.
Corners and edges
The joint between tiles and a bath, tray or worktop gets silicone. Grout in that joint wouldn’t last.
Landlords, agents and businesses in Botany Bay
We also work for property managers and facilities teams in Botany Bay and across Greater London. We can quote a run of properties together, and we are fully insured.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Bathrooms and kitchens in Botany Bay
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
Botany Bay is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Schools such as St. John's Senior School are buildings too, and 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. If you let a flat or house near Crews Hill station, a regrout while the flat is empty is quicker than working around a tenant.

How we quote for regrouting
The quote reflects the job in front of us. We look at:
- Any working-time requirements on site
- The size of the job
- Whether the work is at height
- The type of sealant required
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- The problem you’ve noticed
- Where the property is
- Any access issues, like height or stairs
- Whether it has been sealed before
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
Looking after it afterwards
So the new joints stay in good condition:
- Give the walls a quick rinse after use
- Run the extractor fan during and after a shower
- Stick to mild products for cleaning grout
- Don’t use strong acidic cleaners on grout
A squeegee or cloth over the tiles after use stops soap and water sitting on the grout. Ventilate the room well to help it dry out.
Fixing grout early is a small job. Left, the same problem can let water through so it’s worth dealing with as soon as you spot it.
How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes anything from a few hours to a full day, depending on the area. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Botany Bay. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we agree what’s being done and flag any loose tiles.
- We remove the old grout carefully.
- Dust is cleared from every joint.
- The new grout goes in, then the tile faces are cleaned.
- We renew the silicone at the corners and edges.
Preparing for the visit
- Clear the area around the work
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
