- Shrunken sealant along the back of a worktop
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How we handle bathroom resealing in Hampstead
Before a bath is sealed, it’s filled with water. A full bath sits slightly lower than an empty one, so the bead is not stretched the first time someone gets in. Quick jobs often leave it out, and it makes a real difference. We work on wet rooms, baths and kitchen worktops & upstands, and common reasons people get in touch are gaps between the worktop and the wall and splits where the tray meets the wall.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Hampstead are no different.
All of our work is guaranteed for twelve months.

Aftercare tips
After the cure time, these simple habits help:
- Give the silicone its full cure time
- Check the joints every few months for splits or lifting
- Wipe up water along the back of the worktop
- Squeegee the walls and tray after use
Give the silicone time to cure before it gets wet, which is generally around 24 hours. Once it’s cured, wiping it down after use keeps it looking new.
Mould that starts as a few spots spreads through the bead. Once it’s deep in the silicone, cleaning normally will not remove it. Replacing the sealant early keeps the job small.
What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes half a day or less for one room, longer when the kitchen is included. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Hampstead. It helps if you can point us to a visitor permit or a bay close to the door.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- The joint is cleaned, degreased and treated for mould.
- We let it dry fully and fill the bath with water before sealing.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We tidy up and give you the cure time, normally around 24 hours.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Advice
Do you need bathroom resealing in Hampstead?
The wrong product fails fast. Acrylic caulk and general-purpose sealants aren’t designed for a joint that’s wet every day, so they crack, discolour or grow mould quickly. Wet areas call for a sanitary silicone with an anti-fungal additive.
Keep an eye out for any of the following:
- Gaps where the bath or tray has moved
- Lumpy, uneven sealant from a DIY attempt
- Black mould in the silicone that will not clean off
- New sealant laid over old sealant that is now lifting
Managing a site like Fitzjohn's Primary School? Then 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.

Why act early in Hampstead
Tired sealant is not a reason to replace a bath or shower. A new bead often brings the whole room back, as long as the fittings themselves are sound. If we find a deeper problem, you’ll hear it from us. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email.

Bathroom resealing around Hampstead
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. There are hotels and other places to stay in and around Hampstead. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
In the older streets around St John-at-Hampstead church, walls and floors in older homes can move, and sealant and grout show it first. As a London address, Hampstead can be tricky for parking: let us know about parking bays, permits or a driveway.

Questions from Hampstead
Can you help a landlord with a rental near Finchley Road & Frognal station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Do you work in hotels near Hampstead?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you do kitchens as well as bathrooms?
Yes. Where it’s needed by the sink, we use a food-safe sealant.
Can new silicone go straight over the old?
No, and it’s one of the main reasons reseals fail. We cut out all of the old sealant, clean the joint and start again.
How long does a bath or shower reseal take?
That depends on the number of joints and the state of the old sealant. For most single baths or showers, allow a couple of hours.
Is white the only colour available?
White, clear and a range of colours are available. On a worktop we colour-match where the joint shows.
How the job changes by surface
Kitchen worktops & upstands
The joint between worktop and wall takes splashes, crumbs and cleaning sprays. We seal them in a colour that suits the worktop.
Shower trays & enclosures
If a tray moves underfoot, new silicone won’t last. We check for movement before we reseal, and tell you if it needs re-bedding first.

We quote each job individually. This is what makes a difference:
