Woolwich questions
Can you help a landlord with a rental near Woolwich Dockyard station?
Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Can worn sealant in a flat in Woolwich cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
About our regrouting in Woolwich
A grout colour change can freshen a room without retiling. Light grout can go darker to hide marks or back again. Tell us what you have in mind when you ask for a quote. Common call-outs are for cracked or crumbling grout lines and grout that stays dark however much it’s cleaned, across bathroom wall tiles, bathroom floors and kitchen splashbacks.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Woolwich, that’s a good reason to put tired sealant and grout right early.
Each job carries a 12-month guarantee.

Woolwich homes and their sealant
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. 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.
Woolwich is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a building such as Mulgrave Primary School, 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.

What sealant work can’t fix
A few problems are outside what sealant work can do:
- Tiles that have come away from the wall
- Water coming from plumbing rather than grout
- Damaged tiles that need replacing
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.
What we seal
- Bathroom wall tiles
- Kitchen splashbacks
- Tiled floors
- Shower walls
- Bathroom floors
- Wet rooms
What we do, step by step
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for a shower enclosure, longer for a whole room. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Woolwich. 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.
- We rake out the old grout to an even depth, taking care of the tile edges.
- The joints are vacuumed and cleaned.
- Fresh grout goes into the joints and the tile faces are wiped clean.
- The corners and edges get new silicone, because grout there would crack.
Before we arrive
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

Advice
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Different surfaces, different methods
Kitchen splashbacks
We can regroute a splashback with the kitchen left in place. The worktop edge is finished with silicone.
Bathroom wall tiles
Tiles away from the shower stay drier but still stain and crack. Regrouting brings them back in line.

More about regrouting
Signs you need regrouting in Woolwich
Grout that was put in corners cracks as the bath or tray moves. Those joints should be silicone, and if they’re grouted, a crack soon lets water in.
It’s worth asking for a quote if you see:
- Good tiles let down by tired grout
- Grout stained black or orange that won’t clean
- Corners filled with grout instead of silicone
- Splashback grout that has darkened
If you let a flat or house near Woolwich Dockyard station, a regrout while the flat is empty is quicker than working around a tenant.
What your quote should include
- Which colour the sealant will be
- What guarantee comes with the work
- What product goes in the joint
- When the joint can take water or movement
Why act early in Woolwich
Once grout cracks, water can get behind the tiling. Left alone, that water can loosen tiles or damage the wall, and then you are looking at retiling. Dealing with it now keeps it small. Converted houses in London often have a bathroom above someone else’s living room, 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.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
What you get with us
