City of London: questions and answers
Will you work in a care home in City of London without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Could you schedule work at a campus like Queen Mary's University West Smithfield Campus for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we will set out a timescale with the quote.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Washroom sealing for commercial buildings in City of London
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. Our workmanship is guaranteed for 12 months. We work on vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors, and the failures we are asked to look at most are open joints along basins and vanity units and kitchen worktop joints that can’t be kept clean. A single leaking joint is often how a building in City of London 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.
In City of London, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Swollen or delaminated boards behind panels or vanity tops
- Fittings that move too much to hold a bead
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.
Surfaces we seal
- Vanity units and basins
- IPS panels and cubicles
- Showers, trays and wet room floors
- Kitchens and tea points
- Urinals and WCs
- Accessible toilets and changing rooms
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Keep extract fans working and vents clear
- Act on the first split you see at a shower tray
- Respect the cure time before reopening each room
- Note failing joints building by building
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, a routine look catches failing joints early.
In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Cost factors for washrooms and wet areas
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Access and working height
- Quantities, in metres or numbers
- Removal of failed or old sealant
- Working within restricted access windows
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- Any specification or named product
- A wide shot and a close-up of the area
- The site address and postcode
- Asbestos survey details if the building is older
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. 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.
Before we start on site
- Tell us what induction or permit system the site runs
- Agree which areas must stay open
- For older buildings, check the asbestos register before work
Quotes
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or send details through our quote form.
