How we handle washroom sealing in Strood
In a busy washroom, the sealant normally gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you’re dealing with stained or open joints at kitchen sinks and worktops and gaps where vanity tops meet the wall, we can put it right, on vanity units and basins, kitchens and tea points and accessible toilets and changing rooms alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Strood is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For hospitality businesses in towns like Strood, sealed joints in kitchens and toilets help keep surfaces easy to clean. Environmental health officers look at cleanability, and a sound sanitary or hygienic sealant is part of that.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes half a day to a day per washroom, depending on the number of fittings. Most work in Strood is one building at a time: a school, a unit, an office or a block. Your photographs, drawings or a site visit come first, followed by a fixed quote.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- The right sanitary or food-safe sealant is applied.
- We confirm reopening times for each washroom.
Preparing the site
- Point out parking and an unloading spot
- Make sure the joints can be reached
- Confirm the product named in the specification

Cost factors for washrooms and wet areas
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Travel to remote or island sites
- How accessible the joints are
- Whether the work must be split into stages
- Site requirements such as inductions and permits
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- Any specification or named product
- Photos of the joints, close up and from further back
- The postcode of the building
- Any dates the work must fit around
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or send photos by email.
Different surfaces, different methods
Basins and vanity tops
Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.
Showers and trays
Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Leave signs up until the cure time is over
- Clear standing water from shower floors where possible
- Act on the first split you see at a shower tray
- Include joints in routine washroom inspections
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Why deal with it now?
Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
A quote for washrooms and wet areas depends on how many there are, their condition and the access. Call for a quote.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- A room that stays damp because ventilation isn’t working
- Leaks through tanking or membranes below the finishes

Common questions from Strood clients
Would you work within a site like Medway Maritime Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you plan work around the academic year at somewhere like University for the Creative Arts - Rochester?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is old silicone taken out first?
We strip every bit of the failed bead and wipe away the residue before resealing. That’s what makes the new joint last.
Do you use special sealant for toilets and showers?
Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
Will all the toilets be closed at once?
We phase it so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we will plan around them.
Can you reseal washrooms in healthcare buildings?
We do. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.
Is Strood in your area?
Yes. We take on work across Strood, and the same phone number covers every area.
