For landlords and businesses
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 that we can handle for you.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it 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 Cannon Hill. A visitor permit or a nearby bay makes the visit run more smoothly.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- 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.
- Rooms are handed back in order, each with its cure time.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

Advice
Workplaces and buildings in Cannon Hill
London’s water is hard, which leaves limescale on sealant, grout and taps. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Managing a site like Hillcross Primary School? Then washroom and kitchen sealant can be programmed around term times or opening hours. Cannon Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What we can’t put right
A few problems are outside what sealant work can do:
- Cracked trays or baths rather than failed joints
- Water damage behind the tiles that needs a tiler or builder
- Leaking pipework, valves or wastes (a plumber’s job)
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.
Joints and surfaces we work on

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Don’t leave a failed joint until the next refurbishment
- Check extract fans are actually running
- Pass on the cure time to whoever cleans the rooms
- Log resealing so you know what’s due
Strong chemicals and scourers wear silicone out faster. Ask cleaners to use mild products and soft cloths on the sealant.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
Should I try it myself first?
If you are set on DIY, put the effort into 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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Questions from Cannon Hill
Is parking a problem for a job in Cannon Hill?
Parking in Cannon Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Is Cannon Hill in your area for commercial sealant?
Yes, Cannon Hill is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear quote.
Which products do you use?
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.
How much does commercial sealant cost in Cannon Hill?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.
How long does commercial sealant take?
It depends on the size of the job, but most jobs take as long as the scope needs, from one welfare room to a full building. We’ll give you a better idea when we quote.
Can you reseal between tenancies?
Yes. Send us the addresses and what needs doing, and we will quote for the lot.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
Does commercial work come with a guarantee?
Yes, for 12 months. Mild cleaning and good ventilation help it last.
Why act early in Cannon Hill
Sealant is easy to forget until an audit or inspection is due. Booking it in good time leaves room for the cure time before the visit, without a last-minute rush. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Do you need commercial sealant in Cannon Hill?
Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading. A tray that isn’t fully supported soon tears its seal.
The problems people generally mention when they call include:
- Leaking joints in shower rooms and changing areas
- Whole floors of tired en suites
- Rental bathrooms that need resealing between tenants
- Water marks on ceilings under bathrooms
Rented homes near South Merton station change hands often, and we can quote for one property or a whole portfolio of rentals.
Questions to ask before booking
- How long the guarantee is
- How the colour is chosen
- How hidden problems are handled
- Is the old sealant removed completely?
