About our commercial sealant in Lea Valley
Commercial work is planned around the building, not the other way round. We can work room by room, floor by floor or in batches, and early starts or out-of-hours working can be arranged where it helps. We work on retail & leisure sites, student & care accommodation and welfare facilities, and common reasons people get in touch are failed joints in office kitchens and tea points and failed floor-level joints in accessible wet rooms.
For a small place like Lea Valley, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
A 12-month guarantee comes as standard.

What the job involves on each surface
Hotel bathrooms
In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.
Welfare facilities
Before a health and safety visit or audit, tired sealant is easy to sort. Tell us your deadline and we’ll plan the work and cure time around it.

Will the old sealant be removed?

What else we do in Lea Valley
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep extractor fans working and serviced
- Add sealant to your planned maintenance checks
- Schedule work around occupancy
- Ask cleaners to go gently on the silicone
Extract fans need to work. Where a room has no window, the fan is what dries it out, and that is what keeps mould away.
Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a morning for a small washroom, and a planned programme for bigger sites, depending on the size of the job. For a village or hamlet like Lea Valley, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.

Advice
Honest limits
In fairness, there are a few things sealant will not fix:
- Cracked trays or baths rather than failed joints
- Extraction that isn’t working, which needs an electrician or ventilation contractor
- Assessing what fire stopping a building needs
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Leave it or put it right?
First impressions are often made in the washroom. Black sealant makes a clean room look dirty, and scrubbing will not fix it. New sealant does. In a small place like Lea Valley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

Common problems we fix in Lea Valley
Larger buildings move, and lightweight partitions flex more than masonry. Joints between different materials take the strain and eventually tear.
Common reasons people contact us include:
- Sealant failing again soon after quick repairs
- Worktop sealant that has shrunk and stained
- Water marks on ceilings under bathrooms
- Tired sealant in let properties
For site and facilities teams at buildings such as High Beeches Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.
