Washroom sealing for commercial buildings in Gowkshill

In a commercial washroom, sealant is usually the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. The enquiries we see most involve failed sealant behind washroom basins and sealant stained black around basins and showers, across urinals and WCs, kitchens and tea points and showers, trays and wet room floors. Looking for mastic applicators who cover Gowkshill? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

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

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 spell out the cover before we begin.

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For work around Gowkshill, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  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. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Make sure the joints can be reached
  • Point out parking and an unloading spot
  • Point out any areas we must not close

Advice

Why act early in Gowkshill

Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. A full reseal deals with it and your cleaning team stops chasing it. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Gowkshill, a repair visit takes planning, so it’s better to act early.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

How the job changes by surface

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively so their sealant tends to fail sooner.

Wet-room floors and floor-to-wall joints

Floor edges in wet areas are where water most often escapes. We reseal the floor-to-wall junctions and around drains where sealant is used.

When something else is needed

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

  • Water escaping beneath the floor rather than through a joint
  • Panel boards already damaged by water
  • A room that stays damp because ventilation isn’t working

If you are not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Where we work in Gowkshill

  • Showers, trays and wet room floors
  • Vanity units and basins

Busy facilities in and around Gowkshill

The east of Scotland, where Gowkshill is, gets less rain than the west. Drier weather outside doesn’t help a washroom with poor extraction, where mould gets into silicone fast. There are a number of hotels within about 2 miles of Gowkshill. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.

Church halls and community buildings, such as those at Newtongrange Parish Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard. En suites at hotels like Kirkhill Hotel (1 mile south-west of Gowkshill) are cleaned daily, which wears silicone over time.

Gowkshill is about 2 miles south-east of Bonnyrigg, in Midlothian. Across the EH23 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Midlothian, 34 places are covered, Gowkshill among them. Edinburgh is covered too, some 8 miles away.

We take on washrooms and wet areas across the EH23 postcode area, for business premises of every kind. Streets here include The Crescent and Stobhill Road, and sites on any of them can send details for a fixed quote. Just outside Gowkshill, we also work in Newtongrange (1 mile north), Gorebridge (1 mile south), Mayfield (1 mile north-east), Birkenside (2 miles south) and Easthouses (2 miles north). Bigger towns within reach include Penicuik (7 miles west), Loanhead (4 miles west), Shawfair (5 miles north), Danderhall (4 miles north-west), Rosewell (3 miles west) and Roslin (4 miles west).

For managing agents and facilities managers

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Signs you need washroom sealing in Gowkshill

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting and they discolour and fail early.

Things that normally lead to an enquiry:

  • Kitchen worktop joints that can’t be kept clean
  • Split or peeling sealant at shower trays
  • A new bead over an old one coming away
  • Discoloured joints around urinals and WC pans

On a healthcare site such as Midlothian Community Hospital, which lies north-west of Gowkshill, washroom work starts with the infection-control team’s sign-off.

  • Whether their applicators hold CSCS cards

Choosing a commercial sealant contractor

Gowkshill: questions and answers

Can you work around term dates at a campus such as Newbattle Abbey College?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do hotels near Gowkshill have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Can you clean the mould off instead of resealing?

Not for long. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Do your applicators hold CSCS cards?

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