About our washroom sealing in Maidstone

Whether it’s a single toilet block in Maidstone or a programme across several buildings, the route is the same: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. We work on showers, trays and wet room floors, vanity units and basins and kitchens and tea points, and what we are called in for most is failed sealant behind washroom basins and panel joints letting water behind. Most enquiries from Maidstone start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Healthcare washrooms in a town the size of Maidstone come with infection-control rules and permits. We plan the work with the estates team and follow the site’s estates and infection-control requirements.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Maidstone: questions and answers

Is hospital work, at somewhere like The Somerfield Hospital, something you do?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work around term dates at a campus such as University for the Creative Arts?

Yes. Education sites usually 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.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

What sealant do you use in washrooms?

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.

Do you work in hospitals, clinics and care homes?

Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote before we start.

How long before the toilets can reopen?

Cure times vary by product and temperature. You will get a reopening time for each area, and signs stay up until then.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Common problems we fix in Maidstone

Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.

Clients usually get in touch after noticing one or more of the following:

  • Discoloured joints around urinals and WC pans
  • Shower tray joints that have opened up
  • Washrooms that look worn because of the sealant
  • Failed sealant in a tea point or staff kitchen

Colleges such as MidKent College Maidstone Campus, 1.4 miles to the west of Maidstone, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

What to look for in a quote

  • How long is the guarantee, and what does it include?
  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: for example 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.

How a job runs

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. Bigger buildings in Maidstone are typically done in phases agreed with the site or facilities manager, so the building keeps working. Photos and drawings let us propose a sequence with the quote.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work
  • Confirm the product named in the specification

Advice

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Panel boards already damaged by water
  • Leaks through tanking or membranes below the finishes
  • Condensation from failed extract fans

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.

What we seal

  • Urinals and WCs
  • Accessible toilets and changing rooms
  • Showers, trays and wet room floors
  • Vanity units and basins
  • Kitchens and tea points
  • IPS panels and cubicles

What the job involves on each surface

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.

Busy facilities in and around Maidstone

Two care or nursing homes sit less than 2 miles from Maidstone. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. We plan the work with the manager so residents are disturbed as little as possible. Maidstone lies roughly 31 miles out from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.

At a hospital like The Somerfield Hospital, 1.1 miles north-west of Maidstone, patient and staff washrooms are best done in short phases agreed with the ward. Customer toilets in retail centres such as The Mall Maidstone, 0.5 miles to the north of Maidstone, rarely close, so resealing is phased.
