Bathroom Resealing in Edgware
We cover Edgware for bath, shower, basin, wet room, worktop and sink resealing. Old sealant removed completely, joints prepared properly.
- Mouldy sealant that has gone black
- Gaps where the bath or tray has moved
- A messy, uneven bead from a previous reseal
Why it’s worth doing now in Edgware
Bleach and mould sprays may lighten black marks for a while, but mould that has grown into the sealant tends to return. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Edgware, the repair is bigger than a sealant job.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Bathroom resealing in Edgware
A reseal only lasts if the joint is properly prepared. 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. We work on kitchen worktops & upstands, shower trays & enclosures and wet rooms, and the jobs we see most are cracked, shrunken or lifting silicone 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. A compact bathroom that steams up every day is hard on silicone and grout.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep bottles off the sealant line
- Do not leave water standing on kitchen joints
- Wait for the cure time we give you
- Look for lifting corners and small gaps now and then
Mould needs damp, so keep the room aired. Run the extractor fan during and after a shower, so the silicone gets a chance to dry.
A failed kitchen joint is easy to miss. Water gets behind the upstand and into the edge of a laminate worktop, and the board underneath can swell. A reseal in time can save the worktop.
What happens on the day
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work generally takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. In Edgware, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We cover the area around the joints we are working on.
- Old sealant is sliced away and the residue removed.
- Mould is treated, then the joint is left to dry thoroughly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- The joint is finished neatly and we explain when it can get wet.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

Do you need bathroom resealing in Edgware?
Silicone doesn’t last for ever. Daily water, heat and cleaning products take their toll over the years, and how long it lasts comes down to use, cleaning and ventilation.
These are the problems we’re asked about most:
- Smears of silicone across the tiles
- Gaps where the bath or tray has moved
- A reseal done over the top of the old bead
- Water escaping at the shower enclosure
Schools such as Beit Shvidler Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Edgware homes and their sealant
London’s water is hard, so limescale builds up on sealant, grout and fittings. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
For an older house near a landmark such as St Andrew, walls and floors in older homes can move, and sealant and grout show it first. Letting a property close to Mill Hill Broadway station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Common questions in Edgware
Can you help a landlord with a rental near Mill Hill Broadway station?
Yes. We work for landlords and agents as well as householders. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can worn sealant in a flat in Edgware 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.
How long will the resealing take?
Allow a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. You’ll know how long to expect before work begins.
What colours of sealant can you use?
There’s a choice: clear, white and colours chosen to suit the room. We can help you pick when we quote.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
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.
If you manage several properties in or around Edgware, several properties can go on one quote. Send us the addresses and the work at each.
