Washroom sealing in Nob's Crook, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Site teams most often ask us about failed sealant behind washroom basins and open joints at the base of cubicle panels, on IPS panels and cubicles, accessible toilets and changing rooms and urinals and WCs. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Nob's Crook, that means joint design, primers and backing rod as standard.

Smaller places such as Nob's Crook still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Leave it or put it right?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Older rural buildings around Nob's Crook move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

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

Your questions answered

Could you schedule work at a campus like Eastleigh College - Desborough Campus for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Would you work within a site like Wessex Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Nob's Crook in your area?

Yes. Nob's Crook falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or send details through our quote form.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact.

Can washrooms stay open while you work?

We phase it so there are always facilities open. We work through the building a room or section at a time. Tell us your site hours and access windows and we’ll plan around them.

Is it possible to just clean mouldy silicone?

Usually not. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

Aftercare for building managers

After handover, these steps help:

  • Respect the cure time before reopening each room
  • Keep a record of which washrooms need attention
  • Make sure washroom ventilation is running
  • Act on the first split you see at a shower tray

Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.

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

Office washrooms on sites such as Wessex Business Park (to the north of Nob's Crook) are in use all working day, so resealing is phased to keep some open. For a hotel such as Marwell Hotel (1.1 miles east of Nob's Crook), resealing en suites a few rooms at a time keeps the rest available.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Leaks through tanking or membranes below the finishes
  • Panel boards already damaged by water
  • Water from plumbing, not from a joint

Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly before you book.

Where we work in Nob's Crook

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

Should maintenance staff do it?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Distance, for remote addresses
  • Any access equipment needed
  • Which sealant the job calls for
  • The site’s rules and procedures

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • Access details, including height
  • Where the site is, with the postcode
  • What the building is and how it’s used
  • When you need the work done

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call 01277 525 020 or email us.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Nob's Crook may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Before we start on site

  • Let building users know which areas are affected
  • Move anything stored against the joints
  • Tell us what induction or permit system the site runs

Getting a fixed quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
