How we handle commercial sealant in Gun Hill
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. Products include Arbo and Everbuild sealants, applied by ARBOMaster approved applicators. Common call-outs are for mouldy bathrooms flagged at a tenancy check and silicone laid over old silicone by a previous contractor, on welfare facilities, retail & leisure sites and hotel bathrooms.
Work in a small place like Gun Hill is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
You get a one-year guarantee, the same in Gun Hill as everywhere else we work.

Why deal with it now?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. New sealant does. Around Gun Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why us?
- More than 20 years in sealant work
- Arbo and Everbuild products
- 180+ five-star Google reviews
- Sanitary silicone with an anti-fungal additive in wet areas

Keeping the joints in good condition
So the new joints stay in good condition:
- Act on lifting sealant before it leaks
- Add sealant to your planned maintenance checks
- Put a squeegee in each shower
- Give housekeeping the cure time for every room
Ask staff to report splits or lifting sealant early. Catching one split early can save a leak later, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
Gun Hill: your questions answered
Is commercial sealant in Gun Hill guaranteed?
All our work, in Gun Hill and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Gun Hill?
Yes, Gun Hill is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is out-of-hours working possible?
It can be arranged for many jobs. The hours are agreed before work starts.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.

What else we do in Gun Hill
Common problems we fix in Gun Hill
A hotel shower or office washroom is used many times a day, and daily cleaning with strong chemicals wears sealant down. That’s why sealant fails sooner.
Common reasons people contact us are:
- Black, stained silicone in guest bathrooms
- Repeated reseals that don’t last
- Water marks on ceilings under bathrooms
- Too many rooms to reseal without closing the building
In and around Gun Hill, as anywhere, good commercial sealant starts with a clean, dry, properly prepared joint.

How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a morning for a small washroom, and a planned programme for bigger sites. For a village or hamlet like Gun Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
How to prepare
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Keep children and pets away from the work area
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Advice
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the job changes by surface
Rental portfolios
Between tenancies is a good time to reseal, so the next tenant moves in to clean, sound joints.
Welfare facilities
Before a health and safety visit or audit, tired sealant is easy to sort. Tell us your deadline and we will schedule around it, cure time included.
