Why it’s worth doing now in Feltham
Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

How we handle washroom sealing in Feltham
Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Every resealed washroom carries our 12-month guarantee. If you’re dealing with gaps where vanity tops meet the wall and failed sealant in a tea point or staff kitchen, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Feltham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a London area such as Feltham, commercial washrooms in offices, hotels and leisure buildings see constant use. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

What else we do in Feltham
Common questions from Feltham clients
Must a hotel around Feltham close while you work?
Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we will plan around them.
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them.
Does the weather affect the 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. Inside work is seldom held up.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Is there a guarantee on the work?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
Is it possible to just clean mouldy silicone?
Usually not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.
When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Loose panels, vanity units or tiles, which need fixing first
- Vanity carcasses that have swollen
- Water from plumbing, not from a joint
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we will tell you honestly.

How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re 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. Planning a London job such as one in Feltham starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- We survey each room, count the joints and note anything behind them that needs another trade.
- We agree which rooms close and when, so users always have somewhere to go.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- 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.
- You get a reopening time for every room, with signage left up until then.
Before we start on site
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Cost factors for washrooms and wet areas
These are the things that shape the price:
- The size and state of each joint
- Removal of failed or old sealant
- Site requirements such as inductions and permits
- The product specified
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Sending details for a quote
However big the job, the same details help:
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
- The product your specification calls for
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Maintenance after handover
A few simple habits keep the new joints working:
- Inspect washroom sealant regularly
- Tell us about infection-control or permit rules before we quote
- Keep a record of which washrooms need attention
- Keep washrooms out of use until we say the sealant has cured
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.
Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.
Sanitary sealant for Feltham buildings
There are plenty of hotels within about 2 miles of Feltham. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest. In London buildings, toilets and showers generally need to stay partly open, so we phase the work core by core or floor by floor with the building manager.
For an occupier at a site such as Maple Industrial Estate, 0.5 miles south of Feltham, the canteen and welfare facilities need cleanable joints as much as any office. For a site such as Ashford Hospital (2.6 miles west of Feltham), sanitary joints in clinical areas need sound, cleanable sealant and a careful method.
Feltham is about 6 miles south-west of Ealing, in Greater London. We cover commercial sites throughout Feltham, for single jobs and planned programmes alike. Feltham is one of 764 places we cover in Greater London. London is covered too, around 14 miles from Feltham.
If you need washroom sealing in TW14 and TW13, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. If your site is on High Street, Railway Terrace and Sandycombe Road or close by, send details and we will quote for washrooms and wet areas. Access to Feltham is via the A244 and B377 among other routes, so getting applicators and materials to site is simple. We also cover Bedfont (1 mile west), Hounslow (1 mile south-west), Hatton (1 mile north), Ashford Common (2 miles south-west) and Cranford (2 miles north) for washrooms and wet areas. A short drive away, we cover London (14 miles east), City of Westminster (12 miles east), Marylebone (12 miles north-east), Kensington (10 miles east), St Pancras (14 miles north-east) and Shoreditch (15 miles east).

Signs you need washroom sealing in Feltham
Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We check for that first and say if it needs a plumber or another trade.
Typical triggers for a call:
- Urinal joints that look unhygienic
- A new bead over an old one coming away
- Kitchen worktop joints that can’t be kept clean
- Open joints at the base of cubicle panels
Halls of residence and teaching buildings at universities such as St Mary's University (to the east of Feltham) are easiest to reseal during vacations.
What to look for in a quote

- Which product they’ll use, and why it suits the joint
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the existing material will be dealt with
