Washroom sealing in Grubb Street

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Washroom sealing in Grubb Street

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on urinals and WCs, vanity units and basins and showers, trays and wet room floors, and the usual reasons a site gets in touch are urinal joints that look unhygienic and washrooms that look worn because of the sealant. A single leaking joint is often how a building in Grubb Street first comes to us: we look at the rest while we’re there and tell you what we find.

Rural businesses near smaller places such as Grubb Street, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we’ll plan around them.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Leave it or put it right?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. Converted and older buildings near places like Grubb Street tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What the job involves on each surface

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Tell us your site hours and access windows and we’ll plan around them.

Wet-room floors and floor-to-wall joints

Floor edges in wet areas are where water most often escapes. We reseal the floor-to-wall junctions and around drains where sealant is used.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

FAQs: Grubb Street

Can work in a care setting near Grubb Street go ahead while residents are there?

Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.

Can work at a site such as University of Greenwich fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you guarantee washroom sealing?

There is a 12-month guarantee on our workmanship backed by public liability insurance.

Do you cover Grubb Street?

Yes. Grubb Street falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email drawings and photos.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

Is it OK to put new silicone on top of the old?

The whole of the old bead is removed and the surfaces cleaned before resealing. It’s the difference between a joint that lasts and one that peels.

Toilets, showers and kitchens around Grubb Street

Two care or nursing homes sit less than 2 miles from Grubb Street. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Rooms are done a few at a time at times agreed with the home. Grubb Street lies roughly 17 miles out from central London, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available.

For a campus such as University of Greenwich, 2.5 miles north of Grubb Street, showers in residences and washrooms in teaching blocks can be programmed around term dates. If you manage an office at a site such as Fawkham Business Park (0.8 miles south-east of Grubb Street), the washrooms and tea points can be done a floor at a time. Church halls and community buildings, such as those at Church of Saint Mary Magdalene, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Avoid scourers and harsh descalers on silicone
  • Respect the cure time before reopening each room
  • Photograph and log failed joints across the estate
  • Clear standing water from shower floors where possible

Each room goes back into use only when the sealant has cured enough. You’ll be told when showers and basins can be used again, and it helps if signs stay up until then.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Jobs in and around smaller places like Grubb Street are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

What we need from you

  • Let building users know which areas are affected
  • Tell us which areas need to stay in use
  • Make sure the joints can be reached

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
