Our process
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. In Angel, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Every room is surveyed and the failed joints listed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Each joint is cleaned and left dry.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Each area is handed back when ready.
Preparing the site
- Send any specification or drawings in advance
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or send photos by email.

Washroom sealing for commercial buildings in Angel
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. We work on accessible toilets and changing rooms, showers, trays and wet room floors and kitchens and tea points, and the usual reasons a site gets in touch are gaps where vanity tops meet the wall and stained sealant around pans and urinals. Looking for mastic applicators who cover Angel? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In Angel, 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 behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

FAQs: Angel
Will you work in a care home in Angel without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.
Can you take on a job at a hospital such as Moorfields Eye Hospital (City Road campus)?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Will cleaning remove black mould from sealant?
Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
What guarantee comes with washroom resealing?
Our workmanship has a 12-month guarantee backed by public liability insurance.
Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Owners, agents and contractors
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Busy facilities in and around Angel
A London building with hundreds of occupants can’t lose every washroom for a day, so we take one block of facilities out of use at a time. The area within 2 miles of Angel holds a good number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.
On a healthcare site such as Moorfields Eye Hospital (City Road campus), 0.8 miles south-east of Angel, washroom work starts with the infection-control team’s sign-off. Student showers at universities like Paris Dauphine University - London Campus (to the west of Angel) see more use than most, and their silicone shows it. Toilets at colleges like City and Islington College, less than half a mile to the south-east of Angel, take heavy use from students and staff alike.

What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Fittings that move too much to hold a bead
- Water from plumbing, not from a joint
- Leaks through tanking or membranes below the finishes
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think.
Where we work in Angel
- Vanity units and basins
- IPS panels and cubicles
- Showers, trays and wet room floors
- Kitchens and tea points
- Accessible toilets and changing rooms
- Urinals and WCs
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Inspect washroom sealant regularly
- Photograph and log failed joints across the estate
- Leave signs up until the cure time is over
- Report split joints at trays and basins early
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.
Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.
Cost factors for washrooms and wet areas
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Removal of failed or old sealant
- Location, for remote and island sites
- Any access equipment needed
- Backing rod, priming and other preparation
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- The site address and postcode
- Anything awkward about access or site hours
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
