About our washroom sealing in Blackfen
Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. Site teams most often ask us about failed sealant in a tea point or staff kitchen and open joints along basins and vanity units, on vanity units and basins, showers, trays and wet room floors and accessible toilets and changing rooms. A single leaking joint is often how a building in Blackfen first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building managers in Blackfen usually 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.
Our 12-month guarantee is about workmanship, not 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.

Cost factors for washrooms and wet areas
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Joint width, depth and condition
- Site requirements such as inductions and permits
- Travel to remote or island sites
- The product specified
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- The product your specification calls for
- Any dates the work must fit around
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email a schedule or drawings.
What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Swollen or delaminated boards behind panels or vanity tops
- Water from plumbing, not from a joint
- Failed tanking beneath a wet-room floor or behind tiles
If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Joints and surfaces we work on
- Urinals and WCs
- IPS panels and cubicles

Sanitary sealant for Blackfen buildings
There are seven care or nursing homes within about 2 miles of Blackfen. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. We plan the work with the manager so residents are disturbed as little as possible. London offices and hotels typically can’t close all their washrooms at once, which is why the work is split into phases agreed in advance.
Office washrooms on sites such as Green Lane Business Park (to the south-west of Blackfen) are in use all working day, so resealing is phased to keep some open. At a hospital like Eltham Community Hospital, which lies west of Blackfen, patient and staff washrooms are best done in short phases agreed with the ward.
Blackfen is about 2 miles east of Eltham, in Greater London. Anywhere in DA15, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places. Sites around London have their own page, about 9 miles away.
Postcode districts covered here: DA15, DA16 and SE9. We cover commercial and managed buildings on Days Lane, Gordon Road and Kent Avenue and the roads nearby. We also cover Falconwood (1 mile north), Avery Hill (1 mile west), East Wickham (1 mile north), New Eltham (1 mile south-west) and Longlands (1 mile south). Further afield, our area takes in London (9 miles north-west), City of Westminster (11 miles north-west), Marylebone (11 miles north-west), Kensington (13 miles west), St Pancras (10 miles north-west) and Shoreditch (9 miles north-west).
What’s near Blackfen
Locally, jobs take us to sites close to The George Staples pub, Harris Academy Falconwood and Shoulder of Mutton Green and the streets around them. For rail, the closest station is Falconwood station, roughly 0.8 miles north-west of the centre. A little further out are Broadway Shopping Centre (2.3 miles east) and Eltham Community Hospital (1.7 miles west). Green spaces nearby include Summer Hill and The Tarn.
What we are called out for in Blackfen
Panels and vanity units move slightly in use and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.
Clients typically get in touch after noticing one or more of the following:
- Failed joints along IPS and cubicle panels
- Sealant stained black around basins and showers
- Kitchen worktop joints that can’t be kept clean
- Washrooms that look worn because of the sealant
For a campus such as University of Greenwich Avery Hill Campus (0.7 miles south-west of Blackfen), showers in residences and washrooms in teaching blocks can be programmed around term dates.
What your quote should include
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed
- The named product and why it was chosen
What the job involves on each surface
Healthcare and care settings
Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Records you need can be confirmed with the quote.
IPS and cubicle panels
Cubicle and IPS panels move when leaned on or knocked, so the sealant has to take that movement. Loose panels are flagged before any sealant goes on.
Blackfen: questions and answers
Can work in a care setting near Blackfen go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Do you take on work at healthcare sites like Eltham Community Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
What sealant do you use in washrooms?
Sanitary silicone with anti-mould additives in most cases. We use neutral-cure versions on stone, some metals and near mirrors.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Is it possible to just clean mouldy silicone?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Blackfen can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We survey each room, count the joints and note anything behind them that needs another trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- The failed silicone is stripped and every face scraped clean of residue.
- 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.
- Rooms reopen after the product’s cure time, and we move to the next.
Preparing the site
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits
- Send your site hours and access windows
