How we handle regrouting in Streatham Hill
We work across Streatham Hill, regrouting bathrooms, showers and kitchens. Out comes the old grout, the joints are cleaned and new grout goes in, and we finish by resealing the edges. We work on tiled floors, bathroom wall tiles and kitchen splashbacks, and common reasons people get in touch are grout that’s cracking and breaking up and gaps where the shower grout has gone.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Streatham Hill, that’s a good reason to put tired sealant and grout right early.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why it’s worth doing now in Streatham Hill
If tiles are loose, regrouting alone isn’t the answer. We point that out first so you know what’s involved. Where the tiles are sound, regrouting is far less disruptive than retiling. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Streatham Hill.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Common questions in Streatham Hill
Do you take on hotel work around Streatham Hill?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can worn sealant in a flat in Streatham Hill 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.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. If we need more, we will ask.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.

Regrouting around Streatham Hill
Streatham Hill has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you live in an older home near Church of St Margaret, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Streatham Hill station change hands often, and a regrout while the flat is empty is quicker than working around a tenant.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Skip wire brushes and scourers
- Don’t use strong acidic cleaners on grout
- Have loose tiles looked at early
- Check the corner silicone every few months
A squeegee or cloth over the tiles after use keeps water off the grout. Ventilate the room well so the grout dries between uses.
Grout that’s washing out of a shower shouldn’t be left. Each shower drives water into the open joints, and that water can reach the wall or the floor below.

Other services in Streatham Hill
Do you need regrouting in Streatham Hill?
Most grout is porous, so water, soap and grime soak into it. Over time it stains, softens and starts to crumble, especially in a shower that’s used every day.
The problems people generally mention when they call include:
- Grout that makes sound tiles look old
- Greasy, stained grout behind the hob
- A grout colour that no longer suits the room
- Grout that stays dark however much it’s cleaned
As a London address, Streatham Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

How the job changes by surface
Kitchen splashbacks
Grout behind the hob and sink works hard. We renew the grout and the worktop sealant.
Corners and edges
We reseal edges at the same time as regrouting, so the whole area is finished together.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
