Bath resealing in Mapesbury, done in place
Preparation is everything in a reseal: old silicone removed, mould treated, the joint cleaned and dried. Only then does the new sealant go on, in a neat, continuous bead. We regularly repair basins & vanity units, kitchen worktops & sinks and shower trays & enclosures, and people most frequently call us about gaps in the seal and discoloured, yellow sealant.
Whatever the size of the job, it’s backed by a one-year guarantee in Mapesbury and across Greater London.

Should I try a DIY kit first?
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
If you’ve already tried a DIY fix, that is fine. We remove the old filler and start again, so it will not stop us repairing it. It does add a little time, so tell us about it when you send photos.
For landlords and businesses
Landlords, letting agents and housing providers in Mapesbury use us as well as householders. Repairing between tenancies keeps void periods short, and it normally costs far less than a refit.
Builders, developers and site managers book us for snagging repairs, fixing chips and scratches before handover so nothing needs replacing. We’re CHAS, Constructionline and SafeContractor accredited.
Honest limits
Before booking, it’s worth knowing the limits too:
- Tiles that move, until they’re refixed
- Gaps too big for silicone alone
- A flexing bath
If in doubt, send photos and we’ll say what we think before you book.

What we do, step by step
On the day itself, there’s little for you to do. Let us in and show us the room, and we will get on with it. The job generally runs to around two hours.
- We cut out and remove all of the old sealant.
- Next we clean the joint and deal with mould.
- The joint is dried thoroughly.
- Baths are filled with water first, so the joint is at its widest.
- We run a new bead of mould-resistant silicone and smooth it neatly, including around the taps.
Getting ready for the visit
- Let the surface dry out before the visit
- Let us know if it has been repaired before
- Have a window or extractor fan available
Ask for a price
Pricing is simple: take a close-up of the damage and a picture from further back, send them over with your postcode, and you will get a fixed price back. There is no charge for the quote and no obligation.
Advice
Looking after it afterwards
Nothing complicated is needed:
- Give the seal a regular clean
- Keep the joints dry
- Keep bottles off the joints
- Reseal when black spots won’t clean off
Do not scrape the sealant with anything sharp, and do not stand bottles on the seal.
Mouldy sealant is more than a cosmetic problem. Resealing early keeps water out of the walls and floor.
What we are called out for in Mapesbury
In time, even good sealant discolours particularly in a well-used bathroom. Steam, soap and movement all wear it down.
The things customers typically mention when they call are:
- Gaps in the seal
- Water getting behind the bath or tray
- Discoloured, yellow sealant
- Black mould in the sealant
