Washroom sealing in Innermessan: the local picture

With the shore within about 1 mile, Innermessan counts as a coastal location, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Bathrooms turned round daily in the busy months need sound, cleanable joints, so we plan the work for quieter weeks where possible. The area within 2 miles of Innermessan holds a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.

Welfare facilities in units on estates such as Castle Kennedy Industrial Estate, 2.4 miles to the south-west of Innermessan, have showers, toilets and kitchens with sealant that works hard. Staff changing rooms and patient toilets at places like Galloway Community Hospital (to the south-west of Innermessan) need cleanable, sound silicone.

Innermessan is about 2 miles north-east of Stranraer, in Dumfries and Galloway. Commercial clients in Innermessan use us for work on washrooms and wet areas, as part of our coverage of Dumfries and Galloway. 139 places across Dumfries and Galloway fall within our area, including Innermessan.

How we handle washroom sealing in Innermessan

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. We work on kitchens and tea points, urinals and WCs and IPS panels and cubicles, and the failures we’re asked to look at most are failed sealant in a tea point or staff kitchen and sealant stained black around basins and showers. Facilities teams, main contractors and managing agents in Innermessan tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places such as Innermessan, washrooms and kitchens are found in hotels, pubs, schools, care homes and halls. Mould grows into sealant in any wet room that doesn’t dry out, and the answer is removal and a fresh bead of anti-mould silicone.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Report faulty extraction promptly
  • Act on the first split you see at a shower tray
  • Leave signs up until the cure time is over
  • Note failing joints building by building

Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well, so reseal when you first spot a split.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Tell us who will meet us and how to get in at your building near Innermessan. That goes into the plan alongside the quote.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  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.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings

Advice

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Water escaping beneath the floor rather than through a joint
  • Hollow tiles or loose panels behind the joint

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

What we seal

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

Different surfaces, different methods

Changing rooms and gyms

We phase work so not every changing area is closed at once. Tell us your site hours and access windows and we will plan around them.

IPS and cubicle panels

Swollen or delaminated boards need replacing, and any we come across will be pointed out.

What we’re called out for in Innermessan

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

If one of these sounds familiar, it’s time for a closer look:

  • Sealant lifting along a tray edge
  • Sealant laid over old silicone and now peeling
  • Black mould inside silicone joints that cleaning can’t shift
  • Washrooms that look worn because of the sealant

For a college such as Dumfries & Galloway College - Stranraer Campus, 2.1 miles south-west of Innermessan, half-term and summer give the windows for washroom work.

Our contractor checklist

Common questions from Innermessan clients

Is Innermessan too small for you to travel to?

No. Places such as Innermessan are covered as much as the big towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Can work at a site such as Dumfries & Galloway College - Stranraer Campus fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you phase washroom resealing?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured, then we move on.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you guarantee washroom sealing?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

Will cleaning remove black mould from sealant?

Not for long. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.

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.

Why deal with it now?

Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Innermessan before they leak.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
