Washroom sealing for commercial buildings in Throcking
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Site teams most often ask us about sealant laid over old silicone and now peeling and stained sealant around pans and urinals, across vanity units and basins, IPS panels and cubicles and kitchens and tea points. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Throcking, that means joint design, primers and backing rod as standard.
Farm shops, cafés and venues in converted rural buildings around places like Throcking have busy toilets and kitchens. We plan the work around bookings and opening times.

Keeping Throcking washrooms open while we work
At about 31 miles from central London, Throcking is within reach of the capital. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased.
Church halls and community buildings, such as those at Holy Trinity Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard. Schools such as Freman College have toilets, changing rooms and kitchens that are best resealed in the holidays. On an industrial estate such as Honeywood Industrial Centre, which lies west of Throcking, staff toilets, showers and canteens are where sanitary sealant takes the most wear.
Throcking is about 6 miles north-east of Stevenage, in Hertfordshire. We send applicators to Throcking for washrooms and wet areas. Our Hertfordshire coverage takes in 371 places, from busy centres to rural villages. For work in that direction, see our London page (31 miles or so).

General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
Why act early in Throcking
Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Around Throcking, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Questions about Throcking
Must every washroom in our Throcking building shut while you work?
Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.
What paperwork can you provide for a job in Throcking?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you guarantee washroom sealing?
Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Throcking, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- 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.
- 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.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Rooms reopen after the product’s cure time, and we move to the next.
Before we start on site
- Send any specification or drawings in advance
- Tell us which areas need to stay in use
- Let us know about inductions and permits

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Quantities, in metres or numbers
- Joint width, depth and condition
- Location, for remote and island sites
- Phasing around occupants
Pricing washrooms and wet areas depends on how many there are, their condition and the access. Ask us for a fixed quote.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Any specification or named product
- Where the site is, with the postcode
- Anything awkward about access or site hours
- When you need the work done
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, speak to us on 01277 525 020 or use the quote form.
What else we do in Throcking
When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Hollow tiles or loose panels behind the joint
- Mould caused by poor ventilation, which will return until the extract is fixed
- Leaks through tanking or membranes below the finishes
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
