Why act early in West Hendon
Guests and staff judge a building by its bathrooms. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing will not fix it. New sealant does. In a flat in West Hendon, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why book with us
- We never seal over old sealant
- We are fully insured
- Tidy, careful work
- ARBOMaster approved applicator

How we quote for commercial sealant
For a quick quote, just ask. The main things that affect it are:
- Access and height
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
What we need to know
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- How we’d reach the joints
- Where the property is
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Note the date each area was done
- Use mild cleaners on sealant, not bleach or abrasives
- Give housekeeping the cure time for every room
- Check extract fans are actually running
Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and mould comes back faster without it.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
What happens on the day
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours per area, with larger sites planned over several visits. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in West Hendon. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start with a site walk to agree the rooms and the timing.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- We check every room and give its cure time for housekeeping.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Clear the area around the work

More services for West Hendon
Do you need commercial sealant in West Hendon?
A hotel shower or office washroom is used many times a day, and daily cleaning with strong chemicals wears sealant down. That is why sealant fails sooner.
Look out for any of the following:
- Washroom sealant that looks dirty however often it’s cleaned
- Tired sealant ahead of a health and safety audit
- Large numbers of bathrooms needing the same work
- Repeated reseals that do not last
If you look after a church, hall or community building such as St Matthias the Apostle church, any kitchen and washrooms need the same sealant care as any other building.

FAQs for West Hendon
Can parking be tricky for a visit in West Hendon?
Parking in West Hendon, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near Hendon station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Is out-of-hours working possible?
That can be arranged for many jobs. We will confirm the working hours with your quote.
