Washroom sealing for Galashiels sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What happens if it’s left?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. In Galashiels, rain and frost work into any failed joint, so small failures grow. Resealing early keeps it a simple job.

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

What you get with us

  • Clear, fixed quotes
  • CSCS-carded applicators
  • 12 months’ guarantee on every job
  • Failed material removed, not covered up

Washroom sealing in Galashiels, done properly

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Our workmanship is guaranteed for 12 months. The enquiries we see most involve washrooms that look worn because of the sealant and resealing that didn’t last because the old bead stayed, across showers, trays and wet room floors, urinals and WCs and vanity units and basins. Most enquiries from Galashiels start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Changing rooms and showers in Scottish town leisure buildings see heavy, wet use. Shower trays, wet room floors and panel joints are where sealant fails first, and they need dry surfaces before resealing.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Common problems we fix in Galashiels

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.

Typical triggers for a call:

  • Shower tray joints that have opened up
  • Open joints along basins and vanity units
  • Panel joints letting water behind
  • Failed sealant in a tea point or staff kitchen

On a healthcare site such as Borders General Hospital, 2.7 miles to the south-east of Galashiels, washroom work starts with the infection-control team’s sign-off.

Before you book anyone

  • How long is the guarantee, and what does it include?
  • Their approach to joint depth and backing
  • Whether primer will be used where the manufacturer specifies it
  • Who will actually carry out the work

Galashiels: questions and answers

Is a hospital such as Borders General Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will the toilets in our Galashiels building be out of use?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Is it possible to just clean mouldy silicone?

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

How soon can a washroom be used after resealing?

The silicone needs time to cure before water reaches it. We plan the phasing around that so facilities are never short.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do you phase washroom resealing?

We phase it so there are always facilities open. We work through the building a room or section at a time around your site hours and access windows.

Busy facilities in and around Galashiels

Galashiels is on Scotland’s drier eastern side. Inside, ventilation and use decide how fast washroom sealant moulds, whatever the weather.

For a college such as Borders College - Galashiels Campus, 0.9 miles south-east of Galashiels, half-term and summer give the windows for washroom work. En suites at hotels like Kingsknowes Hotel, 1.1 miles to the south-east of Galashiels, are cleaned daily, which wears silicone over time.

Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

General trades versus a specialist

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a unit on an estate in Galashiels, tell us about yard access and site rules. Central premises can need a little more planning for parking.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints
  • Warn occupants and staff about the work
