About our washroom sealing in Lisson Grove
Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. Most enquiries involve shower tray joints that have opened up and a new bead over an old one coming away, across accessible toilets and changing rooms, kitchens and tea points and vanity units and basins. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Lisson Grove is the same: the right product in a properly prepared joint.
In a London area such as Lisson Grove, commercial washrooms in offices, hotels and leisure buildings see constant use. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

FAQs: Lisson Grove
Do you take on jobs in Lisson Grove where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough
Can you work around term dates at a campus such as Imperial College London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
What guarantee comes with washroom resealing?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
What will the job cost?
Each job is quoted on its own details. To get one, call 01277 525 020 or send photos by email.
Do you cover Lisson Grove?
Yes. We cover Lisson Grove, and the simplest way to start is to ring 01277 525 020 or send details through our quote form.
Is old silicone taken out first?
The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.
Busy facilities in and around Lisson Grove
In London buildings, toilets and showers generally need to stay partly open, so we take one block of facilities out of use at a time. There are plenty of hotels within about 2 miles of Lisson Grove. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.
Student showers at universities like Imperial College London, 0.6 miles to the south of Lisson Grove, see more use than most, and their silicone shows it. For a college such as City of Westminster College, 1 mile west of Lisson Grove, half-term and summer give the windows for washroom work. Office washrooms on sites such as The Quadrant Business Centre (1.9 miles north-west of Lisson Grove) are in use all working day, so resealing is phased to keep some open.
Lisson Grove is about 1 mile north-west of City of Westminster, in Greater London. Any commercial site in Lisson Grove is covered. We work across 764 places in Greater London, large and small.
Work on washrooms and wet areas is covered throughout NW8, W1H and W2. Buildings on Hall Road, Park Road and Lodge Road are within our area for washrooms and wet areas.

- The site’s rules and procedures

- When you need the work done
- Any specification or named product

On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. All of Greater London is in the ULEZ, and kerbside space in Lisson Grove can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Failed sealant and residue are stripped out.
- The right sanitary or food-safe sealant is applied.
- We confirm reopening times for each washroom.
Preparing the site
- Let us know about inductions and permits
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space
Quotes

Advice
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- A dripping waste or valve behind a panel
- Water escaping beneath the floor rather than through a joint
- Fittings that move too much to hold a bead
If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
