How we handle washroom sealing in How Wood
You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you are dealing with complaints from staff, guests or users about tired washrooms and stained or open joints at kitchen sinks and worktops, we can help. A specialist sealant contractor works differently from a general builder: on jobs in How Wood, preparation and product choice get the time they need.
Around How Wood, washroom work normally comes one building at a time. Photos of each area help us plan the visit and bring the right sealant.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When something else is needed
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Swollen or delaminated boards behind panels or vanity tops
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Fittings that move too much to hold a bead
If you’re not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer.
What we seal
- IPS panels and cubicles
- Vanity units and basins
- Urinals and WCs
- Showers, trays and wet room floors
- Kitchens and tea points
- Accessible toilets and changing rooms

Your questions answered
Would you work within a site like Kingsley Green Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does a hotel in How Wood need to shut while its sealant is renewed?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Do you use special sealant for toilets and showers?
Each area gets the grade that suits it. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
When to call us in How Wood
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.
Site and facilities staff are often the first to spot these:
- Failed sealant behind washroom basins
- Resealing that didn’t last because the old bead stayed
- Mould spotting along silicone joints
- Failed joints along IPS and cubicle panels
Office washrooms on sites such as North Orbital Commercial Park, 1.8 miles to the north-east of How Wood, are in use all working day, so resealing is phased to keep some open.

Sanitary sealant for How Wood buildings
How Wood lies roughly 19 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time. How Wood has a 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. We work a handful of rooms at a time, so the hotel keeps letting the rest.
Pupil toilets at schools like How Wood Primary and Nursery School take heavy daily use, and the holidays give the window to reseal. Halls linked to places like Church of the Holy Trinity host groups all week, which is hard on kitchen and toilet sealant.

Doing it in-house
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Why act early in How Wood
Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
