Leave it or put it right?
When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Halls, stores and units around places like Knapp may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What you get with us
- Coloured sealants to suit the setting, where available
- Colour agreed before work starts
- Workmanship guaranteed for 12 months
- Old sealant cut out, never sealed over

Washroom sealing in Knapp
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. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you are dealing with stained sealant around pans and urinals and split or peeling sealant at shower trays, we can put it right. Facilities teams, main contractors and managing agents in Knapp tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Knapp, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Building owners, agents and FMs in Knapp
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Knapp can sit alongside others in a wider programme.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
When to call us in Knapp
Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.
Site and facilities staff are often the first to spot these:
- Sealant lifting along a tray edge
- Sealant stained black around basins and showers
- Failed sealant in a tea point or staff kitchen
- A new bead over an old one coming away
Healthcare washrooms on sites such as Wessex Hospital, 2.9 miles east of Knapp, are resealed area by area, under the site’s own infection-control rules.

Advice
Washroom sealing around Knapp: how the place shapes the job
Knapp is about 67 miles from central London, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open. The area within 2 miles of Knapp holds a number of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.
If you manage an office at a site such as Sleepy Hollow Business Park, 0.7 miles to the west of Knapp, the washrooms and tea points can be done a floor at a time. At a hotel such as The Potters Heron Hotel (0.5 miles south-east of Knapp), the quieter weeks are the time to reseal bathrooms.

Knapp: questions and answers
Is a hospital such as Wessex Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Knapp off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you do washroom sealing in healthcare settings?
We do. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.
How much does the work cost?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
How the job changes by surface
Basins and vanity tops
Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.
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.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Water escaping beneath the floor rather than through a joint
- Condensation from failed extract fans
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think before you book.
