Regrouting in Holywell, Greater London
We cover Holywell for raking out old, cracked or stained grout and regrouting tiled walls and floors. Old sealant removed completely, joints prepared properly.
- Grout that’s cracking and breaking up
- Kitchen splashback grout stained by grease
- Old grout in a dated colour
How we handle regrouting in Holywell
Grout fills the gaps between tiles, while sealant goes where tiles meet a bath, tray or worktop. Once grout starts to crack or wash away, water can get in behind the tiles. We rake it out and replace it and renew the silicone at the edges. If you are dealing with grout that stays dark however much it’s cleaned and old grout in a dated colour, we can help, on shower walls, bathroom floors and tiled floors alike.
Hard London water leaves limescale on sealant, grout and taps alike. In Holywell, regrouting is as much about a room looking cared for as about keeping water out.
Whatever the size of the job, it’s backed by our one-year guarantee in Holywell and across Greater London.

Holywell questions
Could a tired shower seal in my Holywell flat affect the neighbours below?
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.
I let a flat near Watford High Street station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Do you guarantee regrouting?
There’s a 12-month guarantee on every job.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
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 fails, we can still redo it.

- Loose tiles, which need refixing first
- A leaking shower valve or waste

Regrouting around Holywell
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London has hard water, so limescale builds up on sealant, grout and fittings.
Holywell is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Homes close to St Oswald's Parish Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Watford High Street station change hands often, and stained grout drags a rental down, and regrouting between lets puts that right.

What the job involves on each surface
Bathroom floors
Grout on a floor is walked on as well as wetted. It gets worn and dirty.
Kitchen splashbacks
A splashback can be regrouted without touching the worktop. The worktop edge is finished with silicone.
Why deal with it now?
Regrouting keeps the tiles you already have. Retiling is a much bigger job: stripping, making good, new tiles and new grout, and often a few days without a shower. If the tiles are sound, regrouting is the simpler fix. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Holywell, the repair is bigger than a sealant job.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
