Washroom sealing for South Malling sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Maintenance after handover

A few simple habits keep the new joints working:

  • Don’t leave trays and floors sitting wet
  • Inspect washroom sealant regularly
  • Share your site rules when you send details
  • Report split joints at trays and basins early

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.

In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

About our washroom sealing in South Malling

Whether it’s a single toilet block in South Malling or a programme across several buildings, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. 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 IPS panels and cubicles, accessible toilets and changing rooms and vanity units and basins, and the failures we are asked to look at most are failed joints along IPS and cubicle panels and resealing that didn’t last because the old bead stayed. A single leaking joint is often how a building in South Malling first comes to us: we look at the rest while we’re there and tell you what we find.

Around South Malling, washroom work usually comes one building at a time. A list and photos let us quote and plan so it’s done in one visit where possible.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Leave it or put it right?

A tired washroom says a lot about how a building is run. Visitors notice black sealant before they notice much else. Resealing is a modest task with a very visible payoff. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What you get with us

  • Fully insured
  • CHAS accredited
  • Constructionline member
  • Failed material removed, not covered up

Take a look at what affects the cost or our accreditations and insurance.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Common problems we fix in South Malling

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

It’s worth sending us details if you spot any of the following:

  • Users noticing mouldy joints
  • Discoloured joints around urinals and WC pans
  • Open joints at the base of cubicle panels
  • Sealant laid over old silicone and now peeling

Healthcare washrooms on sites such as Lewes Victoria Hospital (0.8 miles south-west of South Malling) are resealed area by area, under the site’s own infection-control rules.

Questions to ask before you book

  • Proof of insurance
  • How they’ll work around occupants
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How long is the guarantee, and what does it include?

Common questions from South Malling clients

Will our hotel in South Malling need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Will you plan work around the academic year at somewhere like University of Sussex?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How long does a typical visit take?

That varies with the scale of the job, but the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we will set out a timescale with the quote.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

What guarantee comes with washroom resealing?

There is a 12-month guarantee on our workmanship, and we carry public liability insurance.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Commercial clients in South Malling

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Keeping South Malling washrooms open while we work

Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.
