About our washroom sealing in Letchmore Heath
Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on vanity units and basins, urinals and WCs and kitchens and tea points, and what we are called in for most is urinal joints that look unhygienic and a new bead over an old one coming away.

Common questions from Letchmore Heath clients
Is Letchmore Heath too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Must a hotel around Letchmore Heath close while you work?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Which silicone is right for commercial washrooms?
An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
Building owners, agents and FMs in Letchmore Heath
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Common problems we fix in Letchmore Heath
Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old so it peels away quickly.
Clients usually get in touch after noticing something like this:
- Stained or open joints at kitchen sinks and worktops
- Sealant stained black around basins and showers
- Open joints at the base of cubicle panels
- Users noticing mouldy joints
Customer toilets in retail centres such as Colne Valley Retail Park (2.5 miles south-west of Letchmore Heath) rarely close, so resealing is phased.
Questions to ask before you book
- Will RAMS and insurance details be available?
- Can the work be phased to keep areas open?
- How long is the guarantee, and what does it include?
- The named product and why it was chosen
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Failed tanking beneath a wet-room floor or behind tiles
- A dripping waste or valve behind a panel
- Mould caused by poor ventilation, which will return until the extract is fixed
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think.
Surfaces we seal
- Kitchens and tea points
- Showers, trays and wet room floors
- Vanity units and basins
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Urinals and WCs
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Letchmore Heath are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Preparing the site
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed

Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Clear standing water from shower floors where possible
- Tell us about infection-control or permit rules before we quote
- Respect the cure time before reopening each room
- Make sure washroom ventilation is running
Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.
Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Any access equipment needed
- Location, for remote and island sites
- Joint width, depth and condition
- Removal of failed or old sealant
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- The site address and postcode
- A wide shot and a close-up of the area
- Specification clauses that apply
- How the joints are reached, and at what height
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
