Can I do it myself?
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 fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Plan resealing around quiet periods
- Use mild cleaners on sealant, not bleach or abrasives
- Don’t leave a failed joint until the next refurbishment
- Give housekeeping the cure time for every room
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and that’s what keeps mould away.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
Commercial sealant in Brockley: local notes
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
For site and facilities teams at buildings such as Beecroft Garden Primary, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. For buildings such as Church of St Hilda, any kitchen and washrooms need the same sealant care as any other building.

Brockley questions
Can parking be tricky for a visit in Brockley?
Parking in Brockley, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
I let a flat near Crofton Park station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is commercial work guaranteed?
Yes, for 12 months. Regular gentle cleaning and working extraction help the sealant last.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Can you reseal hotel rooms while we stay open?
Usually, yes. The order and timing are agreed with your team, and you will know when each room can be used.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What does commercial sealant cost?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or email us with a short description of the job.
How long does commercial sealant take?
That depends on the amount of work, but as a guide it takes a few hours for a single washroom, longer for a whole building. We will tell you when we quote.
Landlords, agents and businesses in Brockley
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Letting agents and landlords in Brockley can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
Do you need commercial sealant in Brockley?
Commercial bathrooms get far more use than domestic ones, and daily cleaning with strong chemicals wears sealant down. That is why sealant fails sooner.
These are the problems we’re asked about most:
- Shower leaks reaching the floor below
- Whole floors of tired en suites
- Tired sealant in let properties
- Failed joints in office kitchens and tea points
For landlords with property near Crofton Park station, sealant work can be quoted for a single flat or a whole portfolio.
