Washroom sealing in Lewisham
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. If you’re dealing with complaints from staff, guests or users about tired washrooms and gaps where vanity tops meet the wall, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lewisham is the same: the right product in a properly prepared joint.
In Lewisham, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
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’re clear about what is covered before work starts.

Wet areas in Lewisham’s workplaces
The 2 miles around Lewisham include five care or nursing homes. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Work is agreed with the manager, around residents’ routines. A 2-mile radius around Lewisham takes in plenty of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping.
Healthcare estates like University Hospital Lewisham, 0.6 miles south-west of Lewisham, expect contractors to follow their permits and cleaning rules in every washroom. At a college such as Christ the King Sixth Form College, which lies north-east of Lewisham, washroom and kitchen sealant is best renewed in the holidays or in phases during term. Customer toilets in retail centres such as Lewisham Shopping Centre, under half a mile north-west of Lewisham, rarely close, so resealing is phased.

Why act early in Lewisham
Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Getting scaffold, permits or access booked in Lewisham takes effort, so it makes sense to deal with every failing joint while access is in place.
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.

FAQs: Lewisham
Could you schedule work at a campus like University of Greenwich - Greenwich Campus for the vacation?
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.
Will you work in a care home in Lewisham without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Is it OK to put new silicone on top of the old?
We strip every bit of the failed bead and wipe away the residue before resealing. It’s the difference between a joint that lasts and one that peels.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Tell us about infection-control or permit rules before we quote
- Don’t leave trays and floors sitting wet
- Leave signs up until the cure time is over
- Report faulty extraction promptly
Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.
Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.
Owners, agents and contractors
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Surface by surface
IPS and cubicle panels
Panels flex slightly in use so the bead needs to cope with it. Loose panels are flagged before any sealant goes on.
Healthcare and care settings
Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Tell us what records you need and we’ll confirm with the quote.
How the quote is worked out
We price every job individually. The things that drive the figure:
- Whether old sealant has to be cut out first
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
- Travel to remote or island sites
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- Access details, including height
- Asbestos survey details if the building is older
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or use the quote form to discuss it first.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. In Lewisham, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Each room is handed back once the sealant has had its cure time.
Preparing the site
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space
- Tell us which areas need to stay in use
