Building managers in Finsbury Park typically need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand, so staff and visitors can always find an open washroom.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Questions we’re asked in Finsbury Park
Do you take on jobs in Finsbury Park where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Do you work in occupied care homes around Finsbury Park?
Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.
Do you work in hospitals, clinics and care homes?
We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Cost factors for washrooms and wet areas
To price the job, we consider:
- Access and working height
- The site’s rules and procedures
- Removal of failed or old sealant
- Phasing around occupants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Details that help us quote
We can often quote from photos and a few details. It helps to include:
- Clear photographs of the problem areas
- Whether the building will be occupied during the work
- Anything awkward about access or site hours
- The asbestos register, for older buildings
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Signs you need washroom sealing in Finsbury Park
Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.
It’s worth sending us details if you spot any of the following:
- Complaints from staff, guests or users about tired washrooms
- Failed sealant behind washroom basins
- Sealant stained black around basins and showers
- A new bead over an old one coming away
En suites at hotels like Lanark Hotel (to the south-east of Finsbury Park) are cleaned daily, which wears silicone over time.
Questions to ask before you book
- How joint depth will be controlled
- What the guarantee covers, and for how long
- How the existing material will be dealt with
- Their pre-qualification and accreditations
From enquiry to sign-off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in Finsbury Park can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Each room is handed back once the sealant has had its cure time.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Agree which areas must stay open
- Share the asbestos register for older buildings
