Kew: questions and answers
Do hotels near Kew have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.
Can you take on a job at a hospital such as Clayponds Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will cleaning remove black mould from sealant?
Normally not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you guarantee washroom sealing?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Washroom sealing in Kew
In a busy washroom, the sealant usually 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. We work on showers, trays and wet room floors, IPS panels and cubicles and vanity units and basins, and the failures we’re asked to look at most are sealant lifting along a tray edge and discoloured joints around urinals and WC pans. A single leaking joint is often how a building in Kew first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In Kew, 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.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Washroom sealing in Kew: the local picture
Kew has a good number of hotels close by, all within 2 miles. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. Rooms are done in turn so most stay available. In London buildings, toilets and showers generally need to stay partly open, so we take one block of facilities out of use at a time.
Staff changing rooms and patient toilets at places like Clayponds Hospital, 1.2 miles to the north-west of Kew, need cleanable, sound silicone. At a college such as Ealing and West London College, 2.2 miles north-west of Kew, washroom and kitchen sealant is best renewed in the holidays or in phases during term. For a campus such as Richmond American University London, 0.7 miles north of Kew, showers in residences and washrooms in teaching blocks can be programmed around term dates.
Kew is about 2 miles south of Acton, in Greater London. We cover commercial sites throughout Kew. Across Greater London, 764 places are covered, including Kew. London is covered too, some 8 miles away.
Business premises anywhere in W4, TW9 and TW8 are within our area. Streets here include Kew Road, Maze Road and Kent Road, and sites on any of them can send details for a fixed quote. Access to Kew is via the A3000 among other routes. Just outside Kew, we also work in Strand-on-the-Green (1 mile north), Grove Park (1 mile east), North Sheen (1 mile south), Gunnersbury (1 mile north) and Turnham Green (1 mile east). A short drive away, we cover London (8 miles east), City of Westminster (6 miles east), Marylebone (6 miles north-east), Kensington (3 miles east), St Pancras (7 miles north-east) and Shoreditch (9 miles east).

What affects the price in Kew
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The size and state of each joint
- Phasing around occupants
- Removal of failed or old sealant
- The total length or number of joints
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What to include in your enquiry
However big the job, these details speed things up:
- A wide shot and a close-up of the area
- The asbestos register, for older buildings
- The postcode of the building
- Anything awkward about access or site hours
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Leave it or put it right?
Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How the job changes by surface
Basins and vanity tops
A failed joint along a vanity unit lets water into the carcass. Prompt resealing keeps the unit sound.
Healthcare and care settings
We phase washroom sealing so care areas are never left without facilities. Records you need can be confirmed with the quote.
Diagnose, treat, sign off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Planning a London job such as one in Kew starts with access. Send the building rules and access times with your enquiry.
- We survey each room, count the joints and note anything behind them that needs another trade.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- We clean and dry every surface so the new sealant can grip.
- 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
- Tell us what induction or permit system the site runs
- Warn occupants and staff about the work
- Agree which areas must stay open

Advice
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Swollen or delaminated boards behind panels or vanity tops
- Hollow tiles or loose panels behind the joint
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.
