Washroom sealing for businesses in Strathy

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Include joints in routine washroom inspections
  • Clean sealant with gentle products and a soft cloth
  • Make sure washroom ventilation is running
  • Tell us about infection-control or permit rules before we quote

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface over time.

A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well so failed joints are worth acting on quickly.

Signs you need washroom sealing in Strathy

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.

What tends to prompt an enquiry:

  • Failed sealant behind washroom basins
  • Failed joints along IPS and cubicle panels
  • Users noticing mouldy joints
  • Resealing that didn’t last because the old bead stayed

In any commercial washroom in or near Strathy, mouldy sealant is cut out rather than cleaned, and anti-mould sanitary silicone goes on clean, dry joints.

Comparing quotes

  • The terms of the workmanship guarantee
  • Will failed sealant be removed rather than covered?
  • Will RAMS and insurance details be available?
  • The named product and why it was chosen

Our contractor checklist

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Travel to smaller Scottish places like Strathy is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  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. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  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.

Getting the site ready

  • Flag any permit to work we will need
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

Leave it or put it right?

A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Strathy, a repair visit takes planning, so it’s better to act early.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Clear, fixed quotes
  • Work carried out by CSCS-carded applicators
  • RAL and finish matching where the product range allows
  • Coloured sealants to suit the setting, where available

Your questions answered

What documents will you need to give us for a job in Strathy?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Must every washroom in our Strathy building shut while you work?

Normally only some of them, for a short time. We work in phases so other facilities stay open. We’ll tell you the curing time for the product before we start.

How many days will you need on site?

It depends on the scope, though a typical visit typically takes half a day to a day per washroom, depending on the number of fittings. For bigger or phased jobs, we will set out a timescale with the quote.

Is colour matching possible?

It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Do you need to remove the old sealant?

The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

We work for building owners and managing agents on everything from one building to a spread of sites around Strathy. Several sites can go on one quote, which keeps the paperwork simple.

Busy facilities in and around Strathy

Strathy lies within about 1 mile of the sea, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Heavy seasonal use is hard on shower and basin sealant, and the quieter months are the natural time to reseal. Being in the west of Scotland, Strathy gets more rain than eastern areas. Where ventilation is poor, damp washrooms here tend to see black mould in the sealant sooner.

Phased work lets washrooms in and around Strathy stay partly open while sealant is renewed.

Strathy is about 17 miles west of Thurso, in Highland. Looking for washroom sealing in Strathy? We can help, as we do across Highland. 256 places across Highland fall within our area, including Strathy.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Joint width, depth and condition
  • How much there is to seal
  • Access and working height
  • Induction, permit and paperwork requirements

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

What we need to price the job

It doesn’t need to be a full survey. These details are enough to start:

  • When you need the work done
  • Photos of the joints, close up and from further back
  • Specification clauses that apply
  • The type of building and who uses it

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
