Bathroom resealing for homes and businesses in Greenwich
The secret of a lasting bead is the preparation. The old sealant is removed to the last smear, then the joint is cleaned, degreased and treated for mould. New silicone goes on only when the joint is fully dry. If you have failed sealant on the screen profile and cracked, shrunken or lifting silicone, we can help, on wet rooms, basins & vanity units and shower trays & enclosures alike.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Greenwich more than a cosmetic job.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Bathroom resealing in Greenwich: local notes
Greenwich 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 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.
Letting a property close to Maze Hill station? Then a reseal between tenants is a quick way to make the bathroom and kitchen look cared for. Greenwich is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Greenwich is about 4 miles east of London, in Greater London. Across the SE10 area, our applicators can take on bathroom resealing. Our Greater London coverage runs to 764 places, and Greenwich is one of them.
We work across the SE10, SE3 and SE8 postcode area for bathroom resealing and the streets around it. Local streets include Cade Road, Webb Road and Creek Road, and we cover them all.

Near you in Greenwich
Around Greenwich, our work takes us to homes and buildings near The Plume of Feathers pub, John Roan School and Royal School of Naval Architecture and Marine Engineering, among other places. Other local landmarks include Island Gardens (0.6 miles north-west) and St. Paul's (1.1 miles west). There’s a railway station in Greenwich itself: Maze Hill station. Nearby you’ll also find Greenwich Castle (under half a mile south-west) and Greenwich District Hospital (0.5 miles north-east). For a walk, there’s Tower Hill and Creekside Discovery Centre.
Why act early in Greenwich
Most of the work in a good reseal happens before any silicone goes on: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Without that preparation, the new bead won’t last. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Greenwich, the repair is bigger than a sealant job.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

What affects the cost of bathroom resealing
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The amount of work
- When we can work, for business premises
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.
What we need to know
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- If someone has resealed it before
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
For bathroom resealing in Greenwich, call 0345 464 0079 or email us. Tell us what the problem is and where, and we will agree the price before any work begins.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Dry worktop joints after washing up
- Let new sealant cure fully before it gets wet
- Avoid abrasive pads on the sealant
- Squeegee the walls and tray after use
Keep bottles and razors off the sealant line, because they trap water against the silicone. A quick squeegee after showering helps the joint dry.
Mould that starts as a few spots spreads through the bead. Once it’s deep in the silicone, cleaning generally will not remove it. Replacing the sealant early keeps the job small.
Greenwich: your questions answered
Can worn sealant in a flat in Greenwich 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.
Do you take on hotel work around Greenwich?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
My sealant has gone black. Can you sort it?
Yes, by replacing the sealant. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Good ventilation helps keep it away.
Is it OK to put new sealant on top of the old bead?
No. New silicone won’t bond to old silicone, so it lifts and traps water and mould underneath. All the old sealant comes out first.
What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. For a job in Greenwich, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We protect the area and cut out all of the old sealant, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We clear away and tell you when it can get wet, generally after around 24 hours.
How to prepare
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

How the job changes by surface
Basins & vanity units
On a basin, neatness shows: the bead is right in front of you, so it’s tooled cleanly and evenly, in white, clear or a colour to suit.
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, since cooking leaves a film that stops silicone sticking. Proper degreasing is what helps the new joint last.
What sealant work cannot fix
Sealant is not the answer to every problem, and we’ll tell you before any work starts. It won’t solve:
- A cracked shower tray or bath (that needs repair or replacement)
- Loose or hollow tiles, or failed tanking behind them
- Failed grout lines across the wall
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What we are called out for in Greenwich
The wrong product fails fast. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
Most people get in touch after spotting something like this:
- A joint torn by a bath that flexes
- Water escaping at the shower enclosure
- Water getting behind the bath panel
- Black mould in the silicone that won’t clean off
For site and facilities teams at buildings such as Meridian Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
