Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Leave squeegees in busy showers
- Do not leave a failed joint until the next refurbishment
- Plan resealing around quiet periods
- Note the date each area was done
Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.
Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.
Commercial sealant in Cadnam
Hotel bathrooms take hard daily use and constant cleaning, so sealant there has a hard life. We work through rooms in batches, so only a few are out of use at once. We work on welfare facilities, hotel bathrooms and rental portfolios, and people most often call us about failed floor-level joints in accessible wet rooms and silicone laid over old silicone by a previous contractor.
For holiday lets, converted business premises or a community building near Cadnam, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
All our work comes with our one-year guarantee, wherever you are in Hampshire.

When to call us in Cadnam
Internal washrooms and en suites without a window rely entirely on extraction, and where extraction is poor, damp hangs around. That’s when black mould sets into the bead.
Common reasons people contact us include:
- Rental bathrooms that need resealing between tenants
- Repeated reseals that do not last
- Washrooms that need sorting before an inspection
- Leaking joints in shower rooms and changing areas
Community buildings like Church of St Mary are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.
Before you book anyone
- What insurance they hold
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
- How long to leave it before use
How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take as long as the scope needs, from one welfare room to a full building. Somewhere as small as Cadnam, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We agree a programme with you: which rooms, in what order, at what times.
- Tell us what paperwork your site needs, and we confirm what we can supply 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
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Let us know about parking restrictions

- A broken extractor fan behind the mould problem
- Water coming from plumbing rather than sealant

Landlord and commercial work in Cadnam
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What the job involves on each surface
Hotel bathrooms
We work through hotel rooms in agreed batches, keeping most of the hotel open. Each room is handed back with its cure time for housekeeping.

Common questions in Cadnam
Can you help a landlord with a rental near Ashurst New Forest station?
Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Cadnam in your area for commercial sealant?
Yes. Our work covers London and the South East, and Cadnam is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
How long does commercial sealant take?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on the number of rooms. We’ll tell you when we quote.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Can you send RAMS and insurance details for our site?
We’re fully insured, so start by telling us what your site asks for. Send over your requirements and we’ll confirm what we can provide.
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.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Commercial buildings in Cadnam
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
