Washroom sealing for Perth sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Leaks through tanking or membranes below the finishes
  • Fittings that move too much to hold a bead
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

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

Surfaces we seal

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

Washroom sealing in Perth, done properly

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. Most enquiries involve shower tray joints that have opened up and open joints along basins and vanity units, across accessible toilets and changing rooms, vanity units and basins and kitchens and tea points. One point of contact handles commercial sealant work in Perth from the first photos to the final walk-round, whether it’s one building or several.

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, so areas are closed in turn while it cures.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we’ll come back to it.

Cost factors for washrooms and wet areas

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Whether old sealant has to be cut out first
  • Location, for remote and island sites
  • Which sealant the job calls for
  • How much there is to seal

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • Any dates the work must fit around
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule

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 will arrange a site visit if anything is unclear.

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Your questions answered

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

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Do you take on work at healthcare sites like Perth Royal Infirmary?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

When can showers be used after new sealant?

Cure times vary by product and temperature. You’ll get a reopening time for each area, and signs stay up until then.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you guarantee washroom sealing?

There is a 12-month guarantee on our workmanship backed by public liability insurance.

Washroom sealing in Perth: the local picture

There are 13 care or nursing homes within about 2 miles of Perth. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Each room is kept out of use only as long as the sealant needs. Perth has plenty of hotels close by, all within 2 miles. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. The work can go floor by floor, agreed with housekeeping.

For a hotel such as The Lovat Hotel (under half a mile south of Perth), resealing en suites a few rooms at a time keeps the rest available. Healthcare washrooms on sites such as Perth Royal Infirmary, under half a mile south-west of Perth, are resealed area by area, under the site’s own infection-control rules. Toilets at places like St Catherine's Retail Park (less than half a mile east of Perth) are cleaned constantly, which is hard on silicone.

Perth is about 33 miles north of Edinburgh, in Perth and Kinross. Perth sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 114 places in Perth and Kinross, from busy centres to rural villages. There’s a separate page for Dundee, about 19 miles away.

We cover the PH1 and PH2 postcode districts. For a building on Simpson Square, High Street and Moredun Square or nearby, send details and we will quote for washrooms and wet areas. Main routes into Perth include the A9 and A85, which helps when planning parking and deliveries for the job. If your building is just outside Perth, we cover Oakbank (1 mile south-west), Scoonieburn (2 miles south-east), Tarsappie (2 miles south-east), Milltown of Aberdalgie (3 miles south-west) and Forgandenny (4 miles south). Nearby towns on our patch include Blairgowrie and Rattray (14 miles north), Crieff (15 miles west), Auchterarder (12 miles south-west), Kinross (13 miles south), Coupar Angus (12 miles north-east) and Rattray (14 miles north). Among the larger centres in Perth and Kinross is Perth, and its commercial and public buildings are all within our area.

Local landmarks in Perth

Other landmarks nearby include Murray Royal Hospital (1.2 miles east) and Balhousie Castle (0.6 miles north-east). The countryside around Perth includes St Magdalene's Hill.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Don’t leave an open joint at a basin or tray
  • Brief cleaning staff to treat joints gently
  • Keep extract fans working and vents clear
  • Respect the cure time before reopening each room

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.

Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Several buildings in and around Perth can be done on one programme. Share your working hours and access arrangements and we will fit in.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  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.

What we need from you

  • Tell us which areas need to stay in use
  • Tell staff and tenants when we will be in
  • Clear stock, furniture or equipment away from the joints

How the job changes by surface

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.
