Your questions answered
Is a hospital such as Fairfield Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do hotels near Astwick have to close for sealant work?
Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What sealant do you use in washrooms?
An anti-mould sanitary silicone for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Is Astwick in your area?
Yes. We cover Astwick, and the simplest way to start is to call the office on 01277 525 020 or email a schedule or drawings.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
About our washroom sealing in Astwick
Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. The enquiries we see most involve open joints at the base of cubicle panels and stained or open joints at kitchen sinks and worktops, across kitchens and tea points, urinals and WCs and showers, trays and wet room floors. A single leaking joint is often how a building in Astwick first comes to us: we look at the rest while we are there and tell you what we find.
In and around smaller places like Astwick, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Don’t leave trays and floors sitting wet
- Tell us about infection-control or permit rules before we quote
- Report faulty extraction promptly
- Keep washrooms out of use until we say the sealant has cured
Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.
Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.

Keeping Astwick washrooms open while we work
There are several hotels within about 2 miles of Astwick. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest. Astwick is about 37 miles from central London. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.
At a school such as St Mary's CofE Academy Stotfold, changing rooms and kitchens need cleanable joints as much as the toilets. For a hall at a building such as Church of Saint Guthlac, resealing the kitchen and toilets can be fitted between bookings.
Astwick is about 1 mile north of Stotfold, in Hertfordshire. Astwick sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Astwick is one of 371 places we cover in Hertfordshire. For work in that direction, see our London page (37 miles or so).

Different surfaces, different methods
Showers and trays
Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.
Healthcare and care settings
Clinics, hospitals and care homes need joints that can be kept clean. Your infection-control and estates rules are followed as well as site permits.
How the quote is worked out
Before we quote, we look at:
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
- Access and working height
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 we’ll put a fixed figure on it.
What to include in your enquiry
A few photos plus some basic facts will normally do. Please tell us:
- Asbestos survey details if the building is older
- The site address and postcode
- When you need the work done
- Whether the building will be occupied during the work
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, call 01277 525 020 or email drawings and photos.
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Jobs in and around smaller places like Astwick are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We confirm reopening times for each washroom.
Preparing the site
- Tell us what induction or permit system the site runs
- Confirm the product named in the specification
- Clear stock, furniture or equipment away from the joints

Advice
Common problems we fix in Astwick
A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old so it peels away quickly.
Look out for the following:
- Urinal joints that look unhygienic
- Users noticing mouldy joints
- Sealant laid over old silicone and now peeling
- Open joints along basins and vanity units
At a hospital like Fairfield Hospital (2.2 miles south of Astwick), patient and staff washrooms are best done in short phases agreed with the ward.
What to look for in a quote
- How long is the guarantee, and what does it include?
- Whether primer will be used where the manufacturer specifies it
- Will RAMS and insurance details be available?
- Their pre-qualification and accreditations
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Loose panels, vanity units or tiles, which need fixing first
- Vanity carcasses that have swollen
- Condensation from failed extract fans
If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
