Common questions from South Harrow clients
Would you work within a site like Cygnet Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will our hotel in South Harrow need to close for the work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.
Is old silicone taken out first?
The failed bead is always removed. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.
Can you reseal washrooms in healthcare buildings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Washroom sealing for commercial buildings in South Harrow
Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. Most enquiries involve split or peeling sealant at shower trays and failed sealant behind washroom basins, on showers, trays and wet room floors, accessible toilets and changing rooms and IPS panels and cubicles. A specialist sealant contractor works differently from a general builder: on jobs in South Harrow, preparation and product choice get the time they need.
In South Harrow, 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.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Different surfaces, different methods
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
Changing rooms and gyms
Shower areas, wet floor edges and vanity areas all have sealant joints, and we survey them together.
Why act early in South Harrow
Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. Replacement deals with the cause in the joint and cleaners stop fighting a losing battle. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Hollow tiles or loose panels behind the joint
- Condensation from failed extract fans
- Panel boards already damaged by water
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Surfaces we seal
- Urinals and WCs
- Kitchens and tea points

Commercial washrooms in South Harrow
A London building with hundreds of occupants can’t lose every washroom for a day, which is why the work is split into phases agreed in advance. A good number of hotels sit less than 2 miles from South Harrow. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.
Office washrooms on sites such as Harrovian Business Village, 1.1 miles north-east of South Harrow, are in use all working day, so resealing is phased to keep some open. Customer toilets in retail centres such as St. George's Shopping Centre, 1.3 miles to the north-east of South Harrow, rarely close, so resealing is phased. Healthcare estates like Cygnet Hospital (to the east of South Harrow) expect contractors to follow their permits and cleaning rules in every washroom.

From enquiry to sign-off
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a job in South Harrow, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- 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.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- 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
- Tell us your opening times and when work is allowed
