How the job changes by surface
Healthcare and care settings
In healthcare, sealed joints are part of infection control. Your infection-control and estates rules are followed and any permits the site uses.
Kitchens and tea points
Kitchen joints need to be smooth and sealed so they can be cleaned properly. Where food contact is possible, we use a hygienic, food-safe sealant.
Washroom sealing in St Margarets
In a busy washroom, the sealant normally gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. We work on showers, trays and wet room floors, accessible toilets and changing rooms and IPS panels and cubicles, and the usual reasons a site gets in touch are discoloured joints around urinals and WC pans and open joints at the base of cubicle panels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in St Margarets is the same: the right product in a properly prepared joint.
Farm shops, cafés and venues in converted rural buildings around places like St Margarets have busy toilets and kitchens. Tell us your opening times and quiet periods and we’ll plan around them.

Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Report faulty extraction promptly
- Respect the cure time before reopening each room
- Avoid scourers and harsh descalers on silicone
- Inspect washroom sealant regularly
Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.
A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.
Questions we are asked in St Margarets
Is St Margarets too small for you to travel to?
Not at all. St Margarets is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can work at a site such as All Nations Christian College fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you need to remove the old sealant?
The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.
How do you deal with asbestos in old sealant?
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. Removing asbestos is a job for asbestos specialists, not us.
Is there a guarantee on the work?
Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
Can washrooms stay open while you work?
We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we’ll plan around them.
Can you reseal washrooms in healthcare buildings?
We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote.
What sets the cost
Before we quote, we look at:
- The size and state of each joint
- Any access equipment needed
- Location, for remote and island sites
- Removal of failed or old sealant
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
Details that help us quote
Good information means a firmer quote. Helpful details to send:
- Specification clauses that apply
- When you need the work done
- Where the site is, with the postcode
- Whether an asbestos survey exists
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or email drawings and photos with what you know.
Wet areas in St Margarets’s workplaces
Several hotels sit less than 2 miles from St Margarets. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest. St Margarets is about 20 miles from central London, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.
Customer toilets in retail centres such as Madford Retail Park, 3 miles to the west of St Margarets, rarely close, so resealing is phased. At a college such as All Nations Christian College, 1 mile to the north of St Margarets, washroom and kitchen sealant is best renewed in the holidays or in phases during term. Healthcare washrooms on sites such as Hertford County Hospital, 3.8 miles west of St Margarets, are resealed area by area, under the site’s own infection-control rules.

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Leaks through tanking or membranes below the finishes
- Hollow tiles or loose panels behind the joint
- Vanity carcasses that have swollen

Our process
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Smaller jobs around St Margarets can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- We agree which rooms close and when, so users always have somewhere to go.
- We strip out the old bead and clean off the residue left behind.
- 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 building users know which areas are affected
- Send any specification or drawings in advance
Getting a fixed quote
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 photos and a few notes.

Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
