Washroom sealing across Dounby

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

What happens if it’s left?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. For buildings near Dounby, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

  • A Constructionline member, so easy to vet
  • Colour options checked against the specified product
  • CHAS accredited contractor
  • Joints cleaned back to sound surfaces

How we handle washroom sealing in Dounby

You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. Site teams most often ask us about users noticing mouldy joints and kitchen worktop joints that can’t be kept clean, across showers, trays and wet room floors, kitchens and tea points and urinals and WCs. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Dounby it comes down to the same thing: the right product in a properly prepared joint.

Hotels and holiday accommodation in rural Scotland have busy and quiet seasons, so washroom work is often best planned for quieter months.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Toilets, showers and kitchens around Dounby

The sea is no more than about 3 miles from Dounby, and seaside hospitality typically has a peak season that works washrooms hard. Bathrooms turned round daily in the busy months need sound, cleanable joints, so resealing in the quieter months keeps rooms ready. Being in the east of Scotland, Dounby gets less rain than the west coast. Mould in sanitary sealant comes down to ventilation and use more than the weather outside.

For a hotel such as Smithfield Hotel, less than half a mile south-east of Dounby, resealing en suites a few rooms at a time keeps the rest available.

Dounby is about 12 miles north-west of Kirkwall, in the Orkney Islands. Across the KW17 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our the Orkney Islands coverage takes in 51 places, from busy centres to rural villages.

Commercial sites across KW17 are covered for washrooms and wet areas. Streets here include Flett's Park, Back Road and Hillside Road. Close to Dounby, our area also takes in Hourston (1 mile south), Skeabrae (1 mile west), Russland (2 miles south), Harray (3 miles south-east) and Tenston (3 miles south-west). Dounby is one of the busier places in the Orkney Islands, and its commercial and public buildings are all within our area. Where a site is remote or on an island, we plan travel and materials carefully, so include the location in your enquiry.

What sets the cost

We price every job individually. The main factors are:

  • Whether the work must be split into stages
  • Quantities, in metres or numbers
  • How accessible the joints are
  • Location, for remote and island sites

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Access details, including height
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available
  • When you need the work done

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, ring 01277 525 020 or email us.

Your questions answered

What paperwork can you provide for a job in Dounby?

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

Can you take on a job in Dounby, on the island?

Yes. Islands are part of our area, Dounby included. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.

What will the job cost?

Every job gets its own fixed quote. For yours, call 01277 525 020 or email drawings and photos.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Do you take on small jobs?

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

Different surfaces, different methods

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant, and any we come across will be pointed out.

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

Signs you need washroom sealing in Dounby

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 say if it needs a plumber or another trade.

What tends to prompt an enquiry:

  • Open joints along basins and vanity units
  • Complaints from staff, guests or users about tired washrooms
  • Open joints at the base of cubicle panels
  • Mould spotting along silicone joints

Around Dounby, washroom joints are resealed by removing the old silicone completely and laying anti-mould sanitary silicone on dry surfaces.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Their plan for phasing and protecting the area
  • Will CSCS-carded applicators be on site?
  • What site paperwork they can supply

How to choose a sealant contractor

Doing it in-house

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. For a building near Dounby, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  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. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.
