How we handle regrouting in Blackheath
When grout stays dark however much you clean it, the discolouration has generally soaked into the grout. Replacing it is the lasting answer, and it’s a chance to change the colour too. If you have cracked or crumbling grout lines and shower grout that has worn away, we can put it right, on kitchen splashbacks, shower walls and bathroom wall tiles alike.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.
You get a 12-month guarantee, the same in Blackheath as everywhere else we work.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Aftercare tips
Aftercare is simple:
- Run the extractor fan during and after a shower
- Do not ignore a tile that feels loose
- Look at the sealant in the corners now and then
- Skip wire brushes and scourers
Check the corner silicone now and then. It’s the part that moves, so the sealant there will need renewing in time, long before the grout does.
Tiles can come away if failed grout is left. Once that happens, regrouting will not fix it, so it’s worth acting early.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Damaged tiles that need replacing
- Tiles that are loose or hollow behind
- Water coming from plumbing rather than grout
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

How we quote for regrouting
Call for a quick quote. The main things that affect it are:
- The type of sealant required
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Whether it has been sealed before
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- Where the property is
We quote each job on its own. Just phone 0345 464 0079 or send us an email with the details.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes 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 Blackheath. 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.
- Old grout is raked out to a consistent depth without chipping the tiles.
- Dust and debris are vacuumed out of every joint.
- 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
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Regrouting around Blackheath
There are hotels and other places to stay in and around Blackheath. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
If you look after a building such as All Saints' Church of England Primary School Blackheath, we reseal washrooms and kitchens in schools and businesses as well as homes. If you let a flat or house near Blackheath station, a regrout while the flat is empty is quicker than working around a tenant. Homes close to Church of All Saints include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
Blackheath is about 1 mile south-east of Greenwich, in Greater London. We provide regrouting to homes and businesses in Blackheath and the surrounding area. Blackheath is one of 764 places in Greater London we cover.
Our applicators cover all of the SE3, SE13 and SE10 postcode area for regrouting and the streets around it. Whether your property is on Pond Road, Heath Lane and Wemyss Road or anywhere close by, our applicators can take on the job. Other places close to Blackheath include Vanbrugh Park Estate (1 mile north), Greenwich (1 mile north-west), Maze Hill (1 mile north), Lewisham (1 mile south-west) and Westcombe Park (1 mile north-east). We also work in nearby towns such as London (5 miles north-west), City of Westminster (8 miles north-west), Marylebone (7 miles north-west), Kensington (9 miles west), St Pancras (7 miles north-west) and Shoreditch (5 miles north-west).
Landmarks near Blackheath
We work in homes and buildings around The Princess Of Wales Pub, Blackheath Proprietary School and Manor House Gardens, among other places. Blackheath has its own railway station: Blackheath station. A little further out are Lewisham Shopping Centre (1.1 miles south-west) and Royal Observatory (0.7 miles north-west). Not far away are Tower Hill and Birdbrook Road Nature Reserve.
Why it’s worth doing now in Blackheath
It’s tempting to fill a few cracks yourself, but the patches often don’t match, and the old grout keeps failing around them. Doing the full area gives you one colour and sound joints throughout. 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 Blackheath, the repair is bigger than the sealant job would have been.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

Blackheath: your questions answered
Do you work for hotels and guest houses in Blackheath?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
I live in a flat in Blackheath. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Will regrouting fix loose tiles?
Tiles that have come away need sorting first. We’ll point them out at the start.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Is regrouting a chance to pick a new grout colour?
Yes, regrouting is the time to do it. Mention the colour you have in mind when you ring 0345 464 0079 or drop us an email.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
