Washroom sealing in Ashbank

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels, so we look at them closely. We work on accessible toilets and changing rooms, kitchens and tea points and showers, trays and wet room floors, and the usual reasons a site gets in touch are stained or open joints at kitchen sinks and worktops and shower tray joints that have opened up. Looking for mastic applicators who cover Ashbank? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Halls and community buildings near places like Ashbank are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Signs you need washroom sealing in Ashbank

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead so it peels away quickly.

Look out for the following:

  • Open joints at the base of cubicle panels
  • Sealant stained black around basins and showers
  • Shower tray joints that have opened up
  • Stained sealant around pans and urinals

Office washrooms on sites such as Roebuck Business Park (to the east of Ashbank) are in use all working day, so resealing is phased to keep some open.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Whether their applicators hold CSCS cards
  • Which product they’ll use, and why it suits the joint
  • How they’ll work around occupants

Our contractor checklist

General trades versus a specialist

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

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Different surfaces, different methods

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone, so the product is chosen to suit.

Ashbank: questions and answers

Does a hotel in Ashbank need to shut while its sealant is renewed?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Is hospital work, at somewhere like KIMS hospital, something you do?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

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.

Will all the toilets be closed at once?

We phase it so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Will you quote for a small job?

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

How long before the toilets can reopen?

The silicone needs time to cure before water reaches it. We plan the phasing around that so there are always rooms open.

Commercial clients in Ashbank

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

What happens if it’s left?

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. For buildings around smaller places like Ashbank, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. Rural sites near Ashbank may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  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.

What we need from you

  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance
  • Let us know about inductions and permits
