How we handle washroom sealing in Bonnyrigg

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day 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 showers, trays and wet room floors, vanity units and basins and kitchens and tea points, and the usual reasons a site gets in touch are resealing that didn’t last because the old bead stayed and complaints from staff, guests or users about tired washrooms. Whoever orders the work in Bonnyrigg, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Towns the size of Bonnyrigg typically have schools, leisure centres, care homes and hotels, all with washrooms. We replace mouldy or split sealant with anti-mould sanitary silicone, area by area.

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

Common questions from Bonnyrigg clients

Can you work around term dates at a campus such as University of Edinburgh Bioquarter?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a hospital such as Midlothian Community Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

How long does a job like this take?

It depends on the scope, but the work normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Site staff or a sealant specialist?

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.

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. Getting these wrong typically costs more in the end than doing them right.

How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes half a day to a day per washroom, depending on the number of fittings, and our waste is bagged and taken away as we go. If you manage more than one building in Bonnyrigg, they can be grouped, with one quote. Share your working hours and access arrangements and we’ll fit in.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Include joints in routine washroom inspections
  • Squeegee showers and trays after busy periods
  • Mention any site permits or estates rules at quote stage
  • Keep extract fans working and vents clear

Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

What the job involves on each surface

IPS and cubicle panels

Swollen or delaminated boards need replacing and we’ll point out any we see.

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.

Commercial washrooms in Bonnyrigg

Several hotels sit less than 2 miles from Bonnyrigg. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest. Bonnyrigg has two care or nursing homes no more than 2 miles away. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Work is agreed with the manager, around residents’ routines.

At a hospital like Midlothian Community Hospital (0.8 miles north-east of Bonnyrigg), patient and staff washrooms are best done in short phases agreed with the ward. At a university such as University of Edinburgh Bioquarter, which lies north of Bonnyrigg, summer is the usual window for resealing residence bathrooms. Customer toilets in retail centres such as Straiton Retail Park (to the west of Bonnyrigg) rarely close, so resealing is phased.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Condensation from failed extract fans
  • Fittings that move too much to hold a bead
  • Swollen or delaminated boards behind panels or vanity tops

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Surfaces we seal

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

Why act early in Bonnyrigg

Cleaning mouldy sealant only masks it, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. In Bonnyrigg, rain and frost work into any failed joint, so small failures grow. Catch it early and it stays a sealant job.

Pricing washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Call for a quote.
