About our commercial sealant in Thamesmead
Mouldy or split sealant in a commercial building causes more than a bad impression. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. Common call-outs are for tired sealant in let properties and repeated reseals that don’t last, across retail & leisure sites, office washrooms & kitchens and rental portfolios.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Thamesmead needs to stay open, work can be planned outside normal hours.
Every job comes with a 12-month guarantee, wherever you are in Greater London.

Commercial buildings in Thamesmead
London’s water is hard, so limescale builds up on sealant, grout and fittings. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
As a London address, Thamesmead can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Jubilee Primary School, busy washrooms and kitchens can be resealed in phases so they stay open. Letting a property close to Abbey Wood station? Then several rental properties can be resealed on one programme.

Landlord and commercial work in Thamesmead
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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 does not work out, we can still put it right.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a single washroom, longer for a whole building, including the tidy-up. In Thamesmead, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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 we start.
- In each room, the old bead comes out and the joint is 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in

Thamesmead questions
Do you work for landlords with property near Abbey Wood station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Thamesmead in your area for commercial sealant?
Yes, Thamesmead is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
What should I tell you?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Can you work outside opening hours?
Early starts and out-of-hours work can be arranged. Tell us what you need when you ask for a quote.
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. We can always put it right if it fails.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- A broken extractor fan behind the mould problem
- Failed tanking or loose tiles behind the sealant
- Fire risk assessments or certification
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Hotel bathrooms
- Retail & leisure sites
- Rental portfolios
- Student & care accommodation
- Office washrooms & kitchens
- Welfare facilities
Why deal with it now?
First impressions are often made in the washroom. Black sealant makes a clean room look dirty, and scrubbing won’t fix it. New sealant does. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What the job involves on each surface
Office washrooms & kitchens
A row of basins on a vanity top has a long joint that collects water. We renew it in one tidy, continuous bead.
Hotel bathrooms
In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.
